CSV to Excel
Convert CSV files into formatted Excel spreadsheets.
This tool runs entirely in your browser. Your file is never sent anywhere.
Handles quoted fields, commas inside values and auto-detected delimiters (semicolons, tabs) — the output has a bold header row and auto-sized columns.
Frequently asked questions
My CSV uses semicolons — supported?
Yes, the parser auto-detects commas, semicolons and tabs.
Is there a row limit?
No fixed limit — files with tens of thousands of rows convert fine; very large files just take a few seconds.
