Convert Excel to CSV
Turn a spreadsheet into a plain CSV file any other tool can import.
How it works
- Drag and drop your Excel (.xlsx or .xls) file below.
- Click Convert to download as a CSV file.
What this tool does to your file
The sheet is written out as comma-separated values, ready to import anywhere. Three details make the difference between a file that opens cleanly and one that does not. A UTF-8 byte-order mark is written ahead of the first row, because Excel on Windows does not detect UTF-8 and would otherwise read the file in the machine’s local code page — which turns Hungarian’s ő and ű into mojibake in the very program you are most likely to open it with. Every other common reader skips or tolerates it. Rows are padded to the width of the widest row, because CSV consumers index by column position and a ragged file silently shifts values into the wrong column. Line endings are CRLF. Formulas are written as their last calculated value, and only one sheet becomes one CSV — the format has no way to hold more.
What happens to your files
- No account needed — Every tool works as a guest. Signing in raises the limits and keeps your files together, but nothing asks you to register before you get a result.
- It runs in your browser — There is nothing to install and nothing to keep up to date. Files travel to our servers over an encrypted connection, and come back the same way.
- Your files stay yours — Files and results stay in your account until you delete them. Files from a guest session that is never linked to an account are removed automatically after a period of inactivity.
- Size limits, stated up front — Up to 10 MB per file as a guest, and up to 25 MB signed in. You see the limit before you upload, not after.
