How to Create a Comma-Delimited File From Excel

By /

If you’re working with Excel and need to share data with another program—like a database, accounting software, or an online service—you’ll often need a comma-delimited file, also known as a CSV (Comma-Separated Values) file. Creating a CSV from Excel is straightforward, but there are some key steps and tips to ensure your data stays intact. In this guide, we’ll show you exactly how to create a comma-delimited file from Excel, step by step.

What Is a Comma-Delimited File?

A comma-delimited file is a plain text file where each piece of data is separated by a comma. For example:

Name,Email,Phone
John Doe,john@example.com,123-456-7890
Jane Smith,jane@example.com,987-654-3210

Each line represents a row from Excel, and each comma separates individual columns.

Why Use a CSV Instead of Excel’s XLSX Format?

CSV files are useful because:

  • They are universal: Most applications support CSV import/export.

  • They are lightweight: Text files are smaller than Excel’s XLSX files.

  • They simplify data sharing: Easier for databases, websites, and scripts.

  • They avoid formatting issues: Only raw data is exported, no formulas or styles.

Note: CSV files do not store formatting, formulas, or multiple worksheets.

Step 1: Open Your Excel File

  1. Launch Microsoft Excel.

  2. Open the workbook containing the data you want to export.

Make sure your data is clean and organized in columns and rows, with headers if needed.

Step 2: Prepare Your Data

Before saving as CSV:

  • Remove extra blank rows or columns.

  • Ensure no commas exist in your data (or enclose the values in quotes).

  • Keep only one worksheet if possible; CSV saves only the active sheet.

Example: If a column contains “New York, NY”, wrap it in quotes: "New York, NY" to preserve the comma.

Step 3: Save As Comma-Delimited File

  1. Click File → Save As.

  2. Choose the location where you want to save the file.

Step 4: Choose CSV Format

  1. In the Save as type dropdown, select CSV (Comma delimited) (*.csv).

  2. Give your file a descriptive name.

  3. Click Save.

Tip: Excel may warn that only the active sheet will be saved. Click OK if that’s what you want.

Step 5: Verify Your CSV File

After saving:

  1. Locate the CSV file in your folder.

  2. Open it using Notepad or another text editor.

  3. Check that each column is separated by a comma, and data looks correct.

Optional: Open it in Excel again to ensure everything imported correctly.

Tips for Creating Accurate CSV Files

  • Avoid special characters that may break CSV formatting (like quotes or line breaks).

  • Check regional settings: Some systems use semicolons instead of commas as separators.

  • Keep consistent column headers for easier importing.

  • Back up your Excel file before exporting, in case you need formulas or formatting later.

Common Issues and How to Fix Them

Issue Cause Solution
Extra quotes in CSV Text values contain commas Wrap text in quotes or remove commas
Only one sheet exported CSV supports one sheet only Save each sheet as a separate CSV
Data misalignment Incorrect delimiter based on regional settings Change delimiter in Control Panel (Windows) or use quotes
Special characters not showing Encoding issue Save as CSV UTF-8 (Comma delimited) in Excel

FAQs About CSV Files from Excel

1. Can I save multiple sheets in one CSV?
No, CSV files support only one sheet per file. Save each sheet separately.

2. Will formulas work in CSV?
No, CSV stores values only, not formulas or formatting.

3. How do I preserve special characters like accents?
Use CSV UTF-8 (Comma delimited) when saving in Excel.

4. Can I open a CSV in Excel later?
Yes, Excel can open CSV files, but formatting and formulas will not be restored.

5. Is CSV the same as TXT?
Not exactly—TXT is plain text without a required separator, while CSV uses commas to separate columns.

Summary of Key Takeaways

  • CSV files are comma-delimited plain text files widely used for data import/export.
