How to Convert Excel to CSV Online (Free, No Upload)

Convert Excel to CSV in seconds, right in your browser, with no install and no account.

Databases, scripts and import tools usually want CSV, not Excel. Saving from Excel by hand also risks the wrong delimiter or encoding.

The converter reads the first sheet of your .xlsx file and writes a clean CSV. Dates become standard ISO dates, so other tools can read them without guessing.

Your file is processed in your browser and is not uploaded to a server, so it is safe to use with customer or business data.

When to use the Excel to CSV converter

• Importing a spreadsheet into a database

Tip: Only the first sheet is read, and old .xls files are not supported. Save as .xlsx first.
