Mysql export to excel file

The typical way to achieve this is to export to CSV and then load the CSV into Excel.

TL;DR:

• For a server-side Excel-friendly CSV file from a SELECT query, run this:

  SELECT ... FROM someTable WHERE etc
  INTO OUTFILE 'someTableExport.csv' CHARACTER SET utf8mb4
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY ''
  LINES TERMINATED BY 'rn';
  

• For a server-side Excel-friendly CSV file use mysqldump like so:

  mysqldump -h serverHostName -u mysqlUserName -p --tab="someTableExport.csv" --fields-optionally-enclosed-by=0x22 --fields-escaped-by='' --fields-terminated-by=0x2C --lines-terminated-by=0x0D0A --databases databaseName --tables table1 table2 table3
  

• For a client-side Excel-friendly CSV file using mysqlsh (MySQL Shell) like so:

  mysqlsh --user="mysqlUserName" --host="serverHostName" --port=3306 --schema="databaseName"
  # Once connected, run this:
  util.exportTable("tableName", "file:///C:/Users/You/Desktop/test.csv", { dialect: "csv", fieldsEscapedBy: ""})
  

First, a caution about Excel:

Excel’s vs. MySQL’s default CSV formats:

Remember that Excel has its own _{underdocumented} ideas about how CSV files should be formatted and these stand in-contrast to MySQL’s own ideas about CSV files; though Excel is largely compliant with RFC 4180 you still need to prod and poke MySQL and its associated tooling to generate CSV files that Excel won’t misinterpret:

As per the table above, MySQL can generate Excel-friendly CSV files, excepting that SQL NULLs will always be interpreted by Excel as literal text, though it’s trivial to use PowerQuery or even just Find-and-Replace in Excel to replace them with empty cells.

Excel and special CSV text markers

• If any of your text values start with = then you’ll need to manually fudge those as even when quoted Excel will interpret the text following = as a formula instead of literal text.
• Also watch out for leading text like sep= too.

Excel and UTF-8 encoding:

Surprisingly, it wasn’t until Excel was 31 years old (Excel 2016) when Excel added built-in support for UTF-8 encoding in files without needing a BOM, but it still defaults to importing and exporting CSV files using your system-default non-Unicode encoding (e.g. Windows-1252).

• When importing CSV into Excel, be sure to select Codepage 65001 for correct UTF-8 handling as Excel still defaults to non-Unicode-based codepages for some reason.

  • Note that opening a CSV file in Excel won’t display the Text Import Wizard. (As of Excel 2021) you need to copy-and-paste CSV text into Excel and use the popup menu to use the legacy (frozen-in-1994) wizard, or use Data > From Text/CSV on the ribbon to use the newer (but less flexible, imo) PowerQuery-based CSV import wizard:

Your options:

Option 1: Exporting an Excel-friendly CSV using INTO OUTFILE:

• You can do a server-side CSV export by using the INTO OUTFILE clause of a SELECT query.
  • Because this is «normal» SQL that’s executed by the MySQL server this works regardless of whatever MySQL client tool you’re using, so you don’t need to install MySQL Workbench.
  • …but because this is a server-side export you need to have permission to write to the server’s filesystem which you might not have, in which case consider using specialty export tools like mysqldump (see below).
• MySQL’s OUTFILE clause has a number of optional subclauses that must be specified for some-level of compatibility with Excel’s own CSV reader:
  • FIELDS...
    • TERMINATED BY (default: 't', for Excel use ',')
    • [OPTIONALLY] ENCLOSED BY (default: '', should be '"' with the OPTIONALLY keyword)
    • ESCAPED BY (default: '\', for Excel use '')
  • LINES...
    • TERMINATED BY (default: 'n', for Excel use 'rn')
    • STARTING BY (default: '', for Excel you can omit this or use the MySQL default).
  • Do not use ENCLOSED BY (without the preceding OPTIONALLY keyword) as that will enquote all values, regardless of type (i.e. it will enquote int values which will cause Excel (by default) to interpret them as text (strings) instead of numbers).
• Note that there is no option to instruct MySQL to output SQL NULLs as empty-fields, and so Excel will interpet them as unquoted strings of text (i.e. as "NULL"), so you’ll want to do a Find-and-Replace in Excel after importing the file.
• If your INTO OUTFILE <fileName> filename (e.g. 'someTableExport.csv' above) is not an absolute path then it will be saved into your database’s datadir directory. Run SHOW VARIABLES LIKE 'datadir'; to get the path. Note that you might not necessarily have read/write permission for new files under that directory.

So your query (SELECT * FROM document WHERE documentid...) would look something like this:

SELECT
    *
FROM
    document 
WHERE
    documentid IN ( SELECT documentid FROM TaskResult WHERE taskResult = 2429 )
INTO
    OUTFILE 'someTableExport.csv'
    FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"', ESCAPED BY ''
    LINES TERMINATED BY 'rn';

Option 2: Exporting an Excel-friendly CSV using mysqldump:

• To store dump into CSV file using the --tab command-line option, as per mysqldump‘s documentation.
• Unfortunately mysqldump‘s --tab= option won’t work for remote MySQL servers: this is because --tab="fileName.csv" can only represent a path on the server.
  • While you can use stdout redirection to generate a local file (i.e. mysqldump --etc > output.csv) you cannot use the --fields-terminated-by and other format options with stdout, making it useless for Excel-compatible output. So if you’re remote and cannot ssh-in then you will need to use MySQL Shell (mysqlsh) instead (see below).
• Note that mysqldump does not support SELECT queries for dumping data: it does support simple WHERE-style filters with the --where=<expr> option but this doesn’t support things like filtering using an INNER JOIN (though as a workaround you could SELECT into a new table, then run mysqldump on that new table. Note that you cannot use TEMPORARY TABLE with mysqldump as Temporary Tables are connection-scoped).

In the OP’s case, due to limitations inherent in how the --where= command-line option works, they’ll want to export both tables (document and TaskResult) and apply their filter logic in Excel PowerQuery or similar. Perform the export like so:

mysqldump -h serverHostName -u mysqlUserName -p --tab="someTableExport.csv" --fields-optionally-enclosed-by=0x22 --fields-escaped-by='' --fields-terminated-by=0x2C --lines-terminated-by=0x0D0A --databases databaseName --tables document TaskResult

• The above command-line should work without modification in Windows’ cmd.exe, macOS’s zsh, and bash on Linux — provided mysqldump is in your PATH.

• The use of hex-encoded chars means sidestepping the hassle of figurig out how to pass double-quotes and line-breaks as literals in your shell and terminal (0x22 is ", 0x2C is ,, and 0x0D0A is rn).

• Avoid using the --password=<value> (aka -p<value>) option on
  the mysqldump command-line, as it will mean your password will be saved in plaintext to your terminal or console history file, which is an obvious massive security risk.

  • So if you’re in an interactive command-line session need to specify a password then mysqldump will prompt you for the password immediately when the program runs so it won’t be saved to your history file.
  • If you want to run mysqldump in a non-interactive context (e.g. from within a web-application, daemon, or other process) then there’s (normally) no history file to worry about, but you should still consider alternative approaches before resorting to handling passwords in an insecure way.

• If you don’t specify an absolute path but use a short (unqualified) filename like INTO OUTFILE 'output.csv' or INTO OUTFILE './output.csv' theb it will store the output file to the directory specified by SHOW VARIABLES LIKE 'datadir';.

Option 3: Exporting an Excel-friendly CSV using MySQL Workbench:

Unfortunately, you can’t (unless you don’t have any double-quotes anywhere in your data): As of late 2022 MySQL Workbench has an open bug regarding its own CSV export feature: output files never escape double-quote characters in text, so pretty much all CSV-handling software out there will report a malformed CSV file or import data to the wrong columns — so this makes it completely unsuitable for use with Excel.

Option 4: Exporting an Excel-friendly CSV using MySQL Shell (aka mysqlsh):

• This is probably the simplest option, but you might need to install the MySQL Shell as it doesn’t come in-box in most MySQL installations.
• MySQL Shell supports connecting to MySQL Server 5.7 and later (but not older versions). If you’re still using MySQL Server 5.6 or earlier (then you really should update to 5.7 or later anyway) you’ll have to stick with mysqldump run locally on the MySQL Server itself (but you can use an ssh session, of course).
  • The new «MySQL X» protocol (mysqlx://user@host/schema) is not supported by MySQL 5.7, but mysqlsh supports non-X connections with old-style command-line parameters.

1. Install MySQL Shell if it isn’t already installed.
2. If you start MySQL Shell without any command-line arguments (e.g. because you use the Start Menu shortcut on Windows)) then use the connect command to connect.

   • For MySQL 5.7 use connect mysql://username@hostname

   • For MySQL 8.0+ there are a variety of ways to connect, including the «MySQL X» protocol as well as «Classic» connections. Consult the docs for more info.

   • If your username contains literal @ characters then you need to percent-encode them (e.g. if you’re using Azure MySQL then your full username will be like username%40servername@servername.mysql.database.azure.com).

   • Immediately after you submit the connect command you will be prompted for your password interactively.

3. If you can start mysqlsh with arguments, then you can run mysqlsh --user="userName" --host="hostName" --port=3306 --schema="dbName" directly without using the connect command.
4. Once connected, run the util.exportTable(tableName, outputUri, options) command with the following arguments:
   • tableName: your table name.
     • Unfortunately there doesn’t seem to be a way to apply a WHERE filter or export the results of a SELECT query, (though as with mysqldump you could always save your query results to a new TABLE, then export that table, then DROP TABLE when you’re done with it. Remember that TEMPORARY TABLE won’t work here as tables created in one session aren’t visible from any other session — and mysqlsh will have its own session.
   • outputUri: To save the file locally use a file:/// URI.
     • On Windows you can use a forward-slash as a directory-name separator instead of a backslash. e.g. file:///C:/Users/Me/Desktop/export.csv.
   • options: To ensure compatibility with Excel specify { dialect: "csv", fieldsEscapedBy: ""}.
     • The dialect: "csv" option sets Excel-compatible defaults for all-but-one of the OUTFILE parameters, so you must also specify fieldsEscapedBy: "", otherwise SQL NULL will be be rendered as N (literally) while double-quotes and line-breaks inside text values will be backslash-escaped, which Excel doesn’t support.

Если нужно быстро и единоразово выгрузить данные из таблицы MySQL в Exel файл, то помогут следующие способы:

$dbh = new PDO('mysql:dbname=db_name;host=localhost', 'логин', 'пароль');
$sth = $dbh->prepare("SELECT * FROM `test`");
$sth->execute();

Recently I published an article How to Read CSV and Excel File in PHP Using PhpSpreadsheet.  One of the readers asked how to use PhpSpreadsheet to export MySQL database records to the Excel file. The user may need their MySQL data in the Excel or CSV file to read or share it easily. In this article, we discussed how one can export data from a database to Excel and CSV files. In addition to this, we will also study how one can send this exported file as an attachment in the email.

Getting Started

For getting started, you first need to install the PhpSpreadsheet library. I recommend using Composer for the installation of the library. Open the terminal in your project root directory and run the command:

composer require phpoffice/phpspreadsheet

PhpSpreadsheet is the library that provides support for reading and writing different types of file formats. Below is the screenshot of supported file formats.

Our end goal is exporting database table records to the Excel/CSV file. For this, we require a few entries in our database. As an example, I am creating the ‘products’ table by running the below SQL query.

CREATE TABLE `products` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `product_name` varchar(255) NOT NULL,
 `product_sku` varchar(255) NOT NULL,
 `product_price` varchar(255) NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Next, add some dummy entries in the table so you will see a few records in the exported file.

INSERT INTO `products` (`product_name`, `product_sku`, `product_price`) VALUES
('Apple', 'app_111', '$1000'),
('Lenovo', 'len_222', '$999'),
('Samsung', 'sam_689', '$1200'),
('Acer', 'ace_620', '$900');

After this create a config.php file where we write the code for database connection.

config.php

<?php
$db_host = 'DATABASE_HOST';
$db_username = 'DATABASE_USERNAME';
$db_password = 'DATABASE_PASSWORD';
$db_name = 'DATABASE_NAME';
 
$db = new mysqli($db_host, $db_username, $db_password, $db_name);
 
if($db->connect_error){
    die("Unable to connect database: " . $db->connect_error);
}

Make sure to replace the placeholders with the actual values in the above code. This file will be included later to fetch records from the ‘products’ table.

In the next part of the tutorial, I am allocating a separate section for exporting data to Excel, exporting data to CSV, and sending the email with an exported file as an attachment.

Export MySQL Database Data to Excel Using PHP

You have installed the library and also have a database table with few entries. Now you can go ahead and write the actual code which will export an Excel file with data filled in it.

Create a <code>export-to-excel.php</code> file in the root directory. In this file, I will write a SQL query to fetch data from the database, write this data to Excel, and finally send the Excel file to the browser to download automatically.

export-to-excel.php

<?php
require_once "vendor/autoload.php";
require_once "config.php";
 
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterXlsx;
 
$spreadsheet = new Spreadsheet();
$Excel_writer = new Xlsx($spreadsheet);
 
$spreadsheet->setActiveSheetIndex(0);
$activeSheet = $spreadsheet->getActiveSheet();
 
$activeSheet->setCellValue('A1', 'Product Name');
$activeSheet->setCellValue('B1', 'Product SKU');
$activeSheet->setCellValue('C1', 'Product Price');
 
$query = $db->query("SELECT * FROM products");
 
if($query->num_rows > 0) {
    $i = 2;
    while($row = $query->fetch_assoc()) {
        $activeSheet->setCellValue('A'.$i , $row['product_name']);
        $activeSheet->setCellValue('B'.$i , $row['product_sku']);
        $activeSheet->setCellValue('C'.$i , $row['product_price']);
        $i++;
    }
}
 
$filename = 'products.xlsx';
 
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename='. $filename);
header('Cache-Control: max-age=0');
$Excel_writer->save('php://output');

When you run this code on the browser, an Excel file will be downloaded automatically and the Excel sheet will have the following entries.

Export MySQL Database Data to CSV Using PHP

In the previous section, we exported data to an Excel file. If someone is looking to export data in a CSV file then you need to change a few lines in the above code.

export-to-csv.php

<?php
require_once "vendor/autoload.php";
require_once "config.php";
 
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterCsv;
 
$spreadsheet = new Spreadsheet();
$Excel_writer = new Csv($spreadsheet);
 
$spreadsheet->setActiveSheetIndex(0);
$activeSheet = $spreadsheet->getActiveSheet();
 
$activeSheet->setCellValue('A1', 'Product Name');
$activeSheet->setCellValue('B1', 'Product SKU');
$activeSheet->setCellValue('C1', 'Product Price');
 
$query = $db->query("SELECT * FROM products");
 
if($query->num_rows > 0) {
    $i = 2;
    while($row = $query->fetch_assoc()) {
        $activeSheet->setCellValue('A'.$i , $row['product_name']);
        $activeSheet->setCellValue('B'.$i , $row['product_sku']);
        $activeSheet->setCellValue('C'.$i , $row['product_price']);
        $i++;
    }
}
 
$filename = 'products.csv';
 
header('Content-Type: application/text-csv');
header('Content-Disposition: attachment;filename='. $filename);
header('Cache-Control: max-age=0');
$Excel_writer->save('php://output');

Send an Email with File as an Attachment

We have seen how to download the file with data in Excel/CSV format. Some users may want to send the exported file as an attachment in the email. Let’s see how to achieve it.

First, install the PHPMailer library using the command:

composer require phpmailer/phpmailer

After installing the library, you can use any SMTP server to send an email. It’s up to you. You may use your hosting SMTP server, AWS SES, or Gmail SMTP server. If you are going with the Gmail SMTP server read our article Send Email Using Gmail SMTP Server from PHP Script which explains the configuration needed for it.

The previous code download Excel/CSV file automatically. But now, instead of making it downloadable, we will save the file in the directory and then send it as an attachment. In short, we will write the code below for saving the file.

...
...
$filename = 'products.csv';
 
if (!file_exists('files')) {
    mkdir('files', 0755);
}
$Excel_writer->save('files/'.$filename);

Our final code to send the attachment in an email will be as follows:

<?php
require_once "vendor/autoload.php";
require_once "config.php";
 
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterCsv;
 
//Import PHPMailer classes into the global namespace
use PHPMailerPHPMailerPHPMailer;
use PHPMailerPHPMailerException;
 
$spreadsheet = new Spreadsheet();
$Excel_writer = new Csv($spreadsheet);
 
$spreadsheet->setActiveSheetIndex(0);
$activeSheet = $spreadsheet->getActiveSheet();
 
$activeSheet->setCellValue('A1', 'Product Name');
$activeSheet->setCellValue('B1', 'Product SKU');
$activeSheet->setCellValue('C1', 'Product Price');
 
$query = $db->query("SELECT * FROM products");
 
if($query->num_rows > 0) {
    $i = 2;
    while($row = $query->fetch_assoc()) {
        $activeSheet->setCellValue('A'.$i , $row['product_name']);
        $activeSheet->setCellValue('B'.$i , $row['product_sku']);
        $activeSheet->setCellValue('C'.$i , $row['product_price']);
        $i++;
    }
}
 
$filename = 'products.csv';
 
if (!file_exists('files')) {
    mkdir('files', 0755);
}
$Excel_writer->save('files/'.$filename);
 
// send as an attachment
$mail = new PHPMailer(true);
try {
    $mail->isSMTP();
    $mail->Host = 'SMTP_HOST';
    $mail->SMTPAuth = true;
    $mail->Username = 'SMTP_USERNAME';   //username
    $mail->Password = 'SMTP_PASSWORD';   //password
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;
 
    $mail->setFrom('FROM_EMAIL_ADDRESS', 'FROM_NAME');
    $mail->addAddress('RECEPIENT_EMAIL_ADDRESS', 'RECEPIENT_NAME');
 
    $mail->addAttachment('files/'.$filename);
 
    $mail->isHTML(true);
    $mail->Subject = 'Products Sheet';
    $mail->Body    = 'Products Sheet';
 
    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: '. $mail->ErrorInfo;
}

Replace the placeholders with the actual values and an email will be sent with an attachment to the recipient’s email address.

Export MySQL Data To Excel in PHP

Because Excel is the finest format for storing data in a file, exporting data in Excel format is a very important tool that allows users to save data for offline use. You’ll learn how to use PHP and MySQL to export data to Excel.

So the file structure for this example is the following:

• index.php: This is the entry file.
• connection.php: This file is used to connect MySQL with PHP
• generate_excel.php: This is the main PHP file that’ll have an export method to export data into the excel.

Create MySQL Database Table

Let’s create a tasks table that ll all tasks records which will export later on in excel format.

CREATE TABLE `tasks` (
  `id` int(11) NOT NULL,
  `Name` varchar(255) NOT NULL,
  `Status` varchar(255) NOT NULL,
  `Priority` varchar(255) NOT NULL,
  `Date` date NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

--
-- Indexes for table `tasks`
--
ALTER TABLE `tasks`
  ADD PRIMARY KEY (`id`);
--
-- AUTO_INCREMENT for table `tasks`
--
ALTER TABLE `tasks`
  MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=5;
COMMIT;

Now, I’ll insert some sample data into the tasks table.

INSERT INTO `tasks` (`id`, `Name`, `Status`, `Priority`, `Date`) VALUES
(1, 'Task1', 'Completed', 'Low', '2021-09-01'),
(2, 'Task2', 'InProgress', 'High', '2021-03-17'),
(3, 'Mysql', 'Hold', 'Low', '2021-09-22'),
(4, 'API', 'Pending', 'Low', '2021-09-06');

Create MySQL Connection With PHP

We’ll create a connection.php file and add the below code. in this file, We’ll pass the database hostname, database username, database password, and database name.

<?php
Class dbObj{
	/* Database connection start */
	var $dbhost = "localhost";
	var $username = "root";
	var $password = "";
	var $dbname = "test";
	var $conn;
	function getConnstring() {
		$con = mysqli_connect($this->dbhost, $this->username, $this->password, $this->dbname) or die("Connection failed: " . mysqli_connect_error());

		/* check connection */
		if (mysqli_connect_errno()) {
			printf("Connect failed: %sn", mysqli_connect_error());
			exit();
		} else {
			$this->conn = $con;
		}
		return $this->conn;
	}
}
?>

Get the Tasks Data from MySQL Database Table

We’ll receive entries from a MySQL database table tasks and put them in an array so we can show them and export them to an excel file. Added below code into the top of the generate_excel.php file.

include_once("connection.php");
$db = new dbObj();
$connString =  $db->getConnstring();

$sql_query = "SELECT * FROM tasks";
$resultset = mysqli_query($connString, $sql_query) or die("database error:". mysqli_error($conn));
$tasks = array();
while( $rows = mysqli_fetch_assoc($resultset) ) {
	$tasks[] = $rows;
}

Export Data to Excel

Let’s create export features using PHP and export data into excel. We’ll also force the to browser download the file instead of display it. We’ll add the below code into the generate_excel.php file.

if(isset($_POST["ExportType"]))
{
	 
    switch($_POST["ExportType"])
    {
        case "export-to-excel" :
            // Submission from
			$filename = "phpflow_data_export_".date('Ymd') . ".xls";		 
            header("Content-Type: application/vnd.ms-excel");
			header("Content-Disposition: attachment; filename="$filename"");
			ExportFile($tasks);
			//$_POST["ExportType"] = '';
            exit();
        default :
            die("Unknown action : ".$_POST["action"]);
            break;
    }
}
function ExportFile($records) {
	$heading = false;
		if(!empty($records))
		  foreach($records as $row) {
			if(!$heading) {
			  // display field/column names as a first row
			  echo implode("t", array_keys($row)) . "n";
			  $heading = true;
			}
			echo implode("t", array_values($row)) . "n";
		  }
		exit;
}

the code shown above, The switch case block will execute based on the parameter value and the method invoked.
Browsers are being forced to download an excel file.

Create HTML and Display Records with Export Button

Define html layout for display data in table and button to fire export-to-csv action. Added below code into the index.php file.

<?php 
include_once("generate_excel.php");
?>

                <?php endforeach; ?>
            </tbody>
        </table>
    </div>
</div>

We’ve imported the ‘generate_excel.php’ file at the top of the code, which will yield task data for display in the HTML table. We’ve established a dropwodn with a ‘export to excel’ option. All task data will be displayed in an HTML table.

Submit Form Using jQuery

We’ve included a dropdown and need to catch and fire events so that when a user selects an option, the form is submitted. We’ll paste the code below at the bottom of the index.php file.

<script type="text/javascript">
$(document).ready(function() {
jQuery('#Export to excel').bind("click", function() {
var target = $(this).attr('id');
switch(target) {
	case 'export-to-excel' :
	$('#hidden-type').val(target);
	//alert($('#hidden-type').val());
	$('#export-form').submit();
	$('#hidden-type').val('');
	break
}
});
    });
</script>

Result:

I hope its help you!.
