Csv delimiters in excel

Although CSV stands for comma-separated values, it has become a common file type to define simple text files including delimiter-separated data. Thus, a CSV file can use a semicolon or tab character as a delimiter as well. In this guide, we’re going to show you how to change CSV delimiter in Excel.

Changing the delimiter in Excel Options

The first approach in our article is about changing how Excel evaluates CSV files including saving. You can make Excel using semicolon (;) as the delimiter.

1. Open Advanced Options by following File > Options > Advanced.
2. In the Editing options section, find Use system operators
3. Uncheck it to override the system settings.
4. Set Decimal separator to comma (,) and Thousands separator to period (.).
5. Clicking OK ensures that Excel uses semicolon (;) as the delimiter.
   

This setting allows Excel to save CSV files with semicolons (;).

Changing the CSV delimiter when importing files

Excel also allows you to change the delimiter while opening files. This is a more convenient way if you do not want to alter Excel’s entire behavior. Because Excel’s data import features have been updated vastly beginning with 2016, we divided this section into two parts.

Power Query — Excel 2016 and newer

Power Query allows you to choose the delimiter when creating a connection. You can find the option in the Preview dialog. You can create the connection by using From Text/CSV command in Data > Get & Transform Data.

Selecting the file opens the Preview window. Probably, the Power Query guessed the delimiter correctly. However, you can change CSV delimiter easily at a dropdown option.

Use Load or Transform Data buttons to load the data directly into your workbook or modify it in the Power Query window respectively.

Excel 2013 or older

If you are using Excel 2013 or a previous version without the Power Query add-in, you can use Text Import Wizard which shares a similar user interface with Text to Columns wizard.

1. Click Data > Get External Data > From Text to select a file and open the Text Import Wizard.
2. In the first step of the wizard, make sure to select Delimited
3. Click Next button to continue.
   
4. Select one or more delimiters that fits your data. You can see if the data is separated correctly in the Data preview section.
   
5. You can modify data types for columns at the next step. Click Next to continue the third step or click the Finish button to populate the separated data in your worksheet.

Solution

1. Make sure Microsoft Excel is closed before trying to change the CSV delimiter.
2. Open Control Panel.
3. Next, you need to access Regional Settings.
4. Click the “Additional Settings” -button.
5. Find the “List separator” and change it to your preferred delimiter such as a pipe (“|”).

Can a CSV have a different delimiter?

Although the file is defined as Comma Separated Values, the delimiter could be anything. The most common delimiters are: a comma (,), a semicolon (;), a tab (t), a space ( ) and a pipe (|). But theoretically anything can be a delimiter as long as it is consistent.

Where should you add a delimiter?

When designing a data file format, use delimiters that will not appear in the data or padding, or use CSV or SSV forms. When copying from a table into a file, you can insert delimiters independently of columns. For example, to insert a newline character at the end of a line, specify nl=d1 at the end of the column list.

This article will explain how you can change the Excel list delimiter for your CSV (or other) file exports. Because it isn’t always a comma. And setting the delimiter won’t escape or strip the same characters in the values, so it’ll mess up your data quite easily.

Background

If you’re still here, let’s delve into the background of the issue a bit deeper.

I needed to wrangle data stored in a .xlsx file into another form, that another application could read. This file format happened to be CSV. Which brought me into the beautiful world of CSV delimiter configuration in Windows.

What’s a “CSV” -file ?

Stands for “comma-separated values” – A text file that uses a comma to separate values.

Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The use of the comma as a field separator (Delimiter) is the source of the name for this file format.

Normally, that’s simple – just “save as” with a different file format. However, this time I was posed with an issue: the data included both commas (“,”) and semicolons (“;”), both of which are typical delimiters in CSV files. Additionally, I couldn’t wrap the values inside quotes due to limitations in both the export and the import functionality. So I needed to use another character – such as pipe (“|”).

Instead of being able to configure the delimiter in the export (like in any sensible spreadsheet editor, if you ask me!), Excel is just going to use your regional settings and grab the list separator from there. Nice and automatic – probably someone thought this to be user friendly, but instead it makes edge cases a pain.

This means that in English, CSV is going to be values limited by commas, like this:

Value1,Value2,Value3,Value4...

But in Finnish, for example, we’ll be using the semicolon – like so:

Value1;Value2;Value3;Value4...

And I could imagine there are plenty of other locales where you might need to tell the values apart with a semicolon instead of a comma. Or you might even need something totally different!

But simply changing my region to something else isn’t a solution this time. The data I had been supplied had both colons and semicolons in cell values. The data would be incorrectly split and parsed due to that.

However, we can luckily override the delimiter to be almost anything – and it’s all done through the regional settings. Read on to see for yourself!

Solution

So, I started googling. And naturally, I found a couple of examples on how to save a csv file with a different delimiter in Windows 7… Obviously, that’ll help you eventually find your way in Windows 10 or Windows 11 as well, even though the user interfaces are a bit different. But I thought it’s always useful to also document the exact steps!

The guide below should be accurate for Windows 10 and 11, and be “close enough” for Windows 7.

Here are the steps for saving a csv in Excel with a different delimiter, in writing – and see some useful screenshots further below!

So now you know how to save (or export, if you prefer that term) a CSV file with a custom delimiter (anything different than a comma or semicolon, depending on your machine configuration) in Microsoft Office Excel on Windows. If you run into any questions, drop them in the comments-section below!

As an interesting side note, you can use completely nonsensical characters as delimiters! Take the picture below as an example – I actually needed this delimiter for a work project once. A project, that’s probably still running in production…

Big kudos to Barry Stevens for his blog post on the topic! And also to Sami Laiho, for noticing you can’t use the same character as both decimal and list separator 😬..

I don’t see an option immediately in Excel, but I can offer some advice.

Remember that CSV files are Comma Separated Values, which follows a standard: Data, a comma, data, a comma, etc. To break this means it will not follow the specification.

What happens if you have a comma in your data though? Excel will automatically surround that cell’s content with quotation marks ("), so the program importing the file will know when that cell actually ends.

If you do not want a comma as a separator, you can save the file as a CSV still, then edit it manually. Open a text editor like Notepad or Notepad++. Do a search for whatever character you want to use (i.e. in Notepad, go to Edit->Find). If you want a pipe, search for a pipe (|). If you hit any results, do not use this character. To search for a tab easily, I’d recommend using Notepad++.

Once you find that the character you want to use isn’t being used elsewhere in your document, then you can do a Search and Replace. In Notepad, go to Edit->Replace…. In ‘Find what:’, type a comma. In ‘Replace with:’, type the character you want to use for the separator. The next part is to hit Find Next. The reason for this, is that if there are commas in your data as well, this will break your file. Only replace the commas that are delimiters of the data, and nothing in quotation marks.

Once this is done, you can save the file. If you want to import it, I’d recommend renaming it to a .TXT file, so Excel will ask you what the Field Delimiter Character is. If you choose to open a .CSV file, it will automatically use a comma as the delimiter, which is what you don’t want.
