Difference Between Excel Worksheet & Workbook

If you use Microsoft Excel at all to make and edit spreadsheets, you have probably heard of Excel worksheets and workbooks. An Excel workbook is an Excel file that can contain multiple, somewhat independent spreadsheets called Excel worksheets. If you see multiple tabs in Excel files, each of those is an Excel worksheet. Businesses often organize related spreadsheets into a single workbook.

Understanding Microsoft Excel

Microsoft Excel is the most popular spreadsheet program currently in use. Businesses use it for everything from accounting to keeping track of attendance, and home users find a variety of uses for it as well, from tracking schedules to organizing records for tax time.

Excel, part of the Microsoft Office suite of programs, saves data in files called workbooks with the extension .xls or, in more recent editions, .xlsx. These files have become de facto standards in the spreadsheet world, and competing tools such as LibreOffice Calc, Google Sheets and Apple Numbers can open and save Microsoft Excel workbook files.

Note that if you use files from one spreadsheet program in another program, they may not function identically.

Using Excel Worksheets and Workbooks

When creating spreadsheets, you often need to use only a single worksheet inside a workbook to represent data. If you want to create a new workbook in Excel, click Blank workbook when you first open the program or if it is already open, go to the File menu and click New to open a new file.

Even a single worksheet is contained in a workbook. When you have a workbook with more than one worksheet, a set of tabs at the bottom of the screen represent the worksheets in the workbook. To add a new tab and worksheet, click the + button at the bottom of the screen or click the Home tab on the ribbon menu, choose Insert and select Insert Sheet.

Click the tabs to move back and forth between worksheets as you work. You can also drag the tabs with your mouse to reorder them.

Renaming a Worksheet in Excel

When you add a tab, you may want to give it a more evocative name than Excel’s default, which is usually something like Sheet2. To do so, double-click on its name on its tab or right-click on its tab and select Rename.

Type a descriptive name for the worksheet and press the Enter key.

Deleting a Worksheet

If you want to delete a sheet from your workbook, right-click on its tab and select Delete.

You can also click a sheet’s tab to open it, click the Home tab on the ribbon menu, choose Delete and select Delete Sheet.

Whichever method you use to delete a worksheet, you lose any data in that sheet.

Have Excel Duplicate a Sheet

Sometimes it’s useful to duplicate an existing worksheet in a workbook. For example, you may use an Excel spreadsheet as a time sheet or some other type of log and want to add a new sheet for a different time period.

Duplicate an Excel worksheet by right-clicking its tab and selecting Move or Copy. Select the Create a copy check box and select the tab the copy should precede in the Before sheet section. Then, click OK.

References Between Worksheets

Worksheets within a workbook don’t have to be completely independent. You can have cells in one worksheet reference another. To do so, precede the cell column and row with the sheet name, separated by an exclamation point.

That is, to refer to cell A5 on the sheet named Sheet3, use the notation Sheet3!A5 in your Excel formula. This allows you to update the data in one sheet based on changing figures in another sheet.

How to read data from multiple Excel files with SQL Server Integration Services

Problem

I have data in multiple Excel files and all my Excel files are placed in the same folder. I want to create a SQL Server Integration Services (SSIS) Package which can read data from multiple Excel files and load the data into a SQL Server destination table. How can I achieve this using SSIS?

Solution

This tip explains how we can read data from multiple Excel files using SSIS and load the data into a SQL Server destination table. Please follow all the steps below to understand the solution.

Step 1 — Folder Creation

Please create a folder named Excel_Exercise on the C: Drive, and then please create a child folder named Excel_Source. Let’s create three excel files inside the Excel_Source folder. Please refer to the image below as a reference.

We will add data these three Excel files and then we will read data from all these Excel files using SSIS.

Step 2 — Sample Files

I have already created three empty Excel source files in my previous step. Let’s add data into sheet1 of each Excel file as shown below.

Step 3 — SQL Server Destination Table

Let’s create a destination table in which we will load the data after reading from all three Excel files. Please use the below SQL code to create the table.

Step 4 — SSIS Package Creation

Create a package and name it as ImportMultipleExcelFiles, please refer to the image below.

Step 5 — SSIS Package Variables

Please create a variable named FileName, scope of this variable is ImportMultipleExcelFiles, Data type is String. Please refer to the image below.

Step 6 — SSIS Foreach Loop Container

Add a Foreach Loop Container in the Control Flow Task, please refer to the image below.

Step 7 — SSIS Foreach Loop Container Collection

Edit the Foreach Loop Container, in the Collection section change the Enumerator value to «Foreach File Enumerator». Please refer to the image below.

We have to change the Enumerator configuration as shown below.

• Folder: Provide a complete folder path location where all our Excel source files are stored. We have all Excel files stored in C:Excel_ExerciseExcel_Source.
• Files: We need to read the Excel files from our source folder, so please enter *.xls in the Files section, this will make sure our SSIS package will read all available .xls files from the source folder. Here * indicates that the Excel file name can be anything, but file extension will be .xls. If we need to read data from a specific Excel file name then we have to configure it accordingly.
• Retrieve File Name: Please select the Fully Qualified radio button. Please refer to the below image for your reference.

To create variable mappings for the Foreach Loop container, select the «User::FileName» variable and set the Index value to 0 in the Variable Mappings section. Please refer to the image below.

Step 8 — SSIS Data Flow Task

Add a Data Flow Task inside the Foreach Loop Container, please refer to the image below.

Right click on the recently added Data Flow task and click on Properties, please refer to image below.

Please mark the DelayValidation property to True, please refer to the image below.

Step 9 — Excel Source in Data Flow Task

Add an Excel Source in the Data Flow Task and create a new connection to any of the Excel source files.

In my case I used the First_Excel_Souce.xls, please refer to the image below.

Open the Excel Source Connection and make sure it is configured as the shown below.

Step 10 — OLEDB Destination in Data Flow Task

Add an OLE DB Destination task in the Data Flow Task and create a connection to the destination database. Select the destination table (ImportMultipleExcelFiles) and map the available input source columns to the available destination columns. Please refer to the image below.

After adding the OLE DB Destination task, your Data Flow Task should look like the image below.

Step 11 — Configure Dynamic Excel Source Connection

As of now our Excel source connection is fixed to one file named as First_Excel_Source.xls. We have to make the Excel connection dynamic so that it can connect to each Excel file in the source folder. To make the Excel source connection dynamic, please right click on Excel Source Connection and then click on Properties. You can refer to the image below.

Please expand the Expression Properties, then select the Connection String property and then click on the expression icon. Please refer to the image below.

Please copy the below code and paste it in the expression window.

Click on the Evaluate Expression button to sure it doesn’t throw an error then click on the OK button. Please refer to the below image.

Step 12 — Execute SSIS Package

Let’s execute the SSIS package, as you can see from the image below the SSIS package was executed successfully.

Step 13 — Review Final Data

Let’s preview the data in the destination table. As you can see from the image below, the data from all three Excel files is loaded per our requirement.

I am a bit late to this, but I set this up as detailed and it worked fine for the first run. Thereafter the package would stop after the first file, but the loop & data flow tasks were still showing the yellow spinning cog. I eventually seem to have fixed this as follows. 1) Created template file with no records, just headers. I then set the full path and filename of this template file as the FileName variable’s default value. 2) As suggested by Abhilash I set the excel connection’s expression for the ExcelFilePath property rather than for the ConnectionString property. It now appears to be working correctly every time, so just posting here to help anyone else that might be experiencing the same issues. FYI, this is on SQL Server 2017.

The above solution is step by step and to the point and correct

those getting the problem of datatype conversion of a particular column, try to replace null values to blank in excel sheet, again try to run your package in SSIS.

write your own file path in expression, goto expression drag user file path to below box and click evaluate expression it will fetch the location given while

creating variable file-path and value (file path of the excel folder in the value) in the values box.

Step 11: edit properties of excel connection and change expression to «excelfilepath» to evaluate for User::FileName instead of «connectionstring» this much will be enough no need to change connection string value.

Hi Ghanesh. Thanks for the well written instructions. I followed everything but unfortunately, my Excel Source object does not seem to be respecting the delayValidation = True setting in the data flow task. I am getting a validation error when I try to run it. In fact, a red X persists in the Excel Source object. Have you seen this before? Thanks so much.

While this post has been out there for a while, I’ve been running into the same issue over and over and was hoping this would be the solution, but unfortunately it isn’t. I’m running Visual Studio 15 and SQL 16. When attempting to pull data from multiple Excel files (even with the directions posted on this blog), it works perfectly when I test it in VS, pulling from a total of 24 Excel files (all set up identical, naming scheme and columns/data type). When I convert to Package Deployment, then Project Deployment, and finally Deploy, all goes well.

But once I deploy and go to execute the package within SSMS, it only pulls from the first file. Again, even when starting the package over and following the steps here, all works well in VS but once it’s deployed, SSMS only grabs the first file.

Have any of you experienced something like this and if so, would you happen to recall how you corrected it?

Thanks in advance for any help!

Keep in mind about this step ‘Provider=Microsoft.Jet.OLEDB.4.0;Data Source=;Extended Properties=»Excel 8.0;HDR=YES»;’. Donot just copy and paste. first what connectionString appeared in properties when you hardcoded it for initiate it. than change it accordlingly in step 11. I was working on Visual Studio 2013 with excel version 2010 so I had to change like this

‘Provider=Microsoft.ACE.OLEDB.12.0;Data Source= ;Extended Properties=»Excel 12.0 XML;HDR=YES»;’

not like step 11 which is ‘Provider=Microsoft.Jet.OLEDB.4.0;Data Source=;Extended Properties=»Excel 8.0;HDR=YES»;’

We only use SQL Server 2008 at work and it don’t have the option ‘Source Assistant — Add New Source’ (step 9).

Looks like the Source Assistant is a new option in SQL2012 so will not be available in the versions we are using.

Do you have a work around for this step 9?

another option would be to use SSIS.
You can fetch the different Product Categories and store them in an SSIS object variable (a recordset destination in the data flow).
Then you can loop over the different product categories using a for each loop.

Inside the for each loop, you have a simple data flow extracting the data for the current product category and writing it to an Excel file. If you put an expression on the Excel connection manager, you can write to a different Excel file each time.

Visual Studio is a 32-bit application, that’s why you need the 32-bit ACE OLE DB drivers to load Excel files with SSIS in Visual Studio.
However, if you want to run your packages on a server, you still need to have the 64-bit ACE OLE DB drivers.

You can install them side-by-side, by forcing the install through the command line.

You should mention a few of the limitations of SSIS when looping over Excel files:

* all of the Excel files should have the same metadata, e.g. having the same amount of columns with the same column names and the same data types

* the names of the Excel sheet with the data should always be the same
