Excel to CSV Converter

Convert Excel .xlsx spreadsheets into plain CSV files.

What Does the Excel to CSV Converter Do?

This converter extracts data from Excel workbooks (.xlsx) into plain CSV files. Pick which worksheet to convert (first through fourth), and formulas are exported as their calculated values — what you see in Excel is what lands in the CSV. The download includes a UTF-8 BOM so accented text re-opens correctly in Excel, and your workbook is deleted from the server the moment conversion finishes.

How to Convert XLSX to CSV

  1. Upload your .xlsx workbook (up to 20 MB).
  2. Select the worksheet if the data isn't on the first sheet.
  3. Click Convert to CSV — the file downloads named after your workbook.

Why Convert Excel to CSV?

  • Universal imports — CRMs, e-commerce platforms, mailing tools and databases almost universally accept CSV, while XLSX support is hit-or-miss.
  • Programming — every language reads CSV in a couple of lines; parsing XLSX needs libraries.
  • Version control — CSV is diffable text, so data changes are reviewable in Git.
  • Longevity — CSV is the closest thing to an eternal data format; no vendor required.
  • Size — plain text is often dramatically smaller than the equivalent workbook.

Frequently Asked Questions

What happens to my Excel formulas?

They are evaluated and their results exported — a cell showing =SUM(A1:A10) contributes the computed total to the CSV, exactly as displayed in Excel.

Does formatting survive the conversion?

No — CSV is pure data. Colors, fonts, merged cells, charts and multiple sheets have no CSV equivalent. That is the point: clean data, no baggage. Convert each sheet separately if you need more than one.

Can I convert password-protected workbooks?

No — encrypted workbooks cannot be read. Remove the password in Excel (File → Info → Protect Workbook) and re-save first.

Why do dates look different in the CSV?

Dates are exported in the format Excel displays. Note that Excel stores dates as serial numbers internally — if a column was formatted as General, you may see those numbers; format the column as a date in Excel before converting.
