Convert CSV to Excel

This tool converts a CSV (or TSV) file into a proper Excel (.xlsx) workbook with LibreOffice, so your data opens cleanly in Excel with real columns instead of raw text.

When to use it

  • Open messy CSV data neatly in Excel.
  • Turn an export into a shareable workbook.
  • Prepare CSV data for formatting and formulas.

Private & secure

Your file is uploaded over an encrypted HTTPS connection, converted on our server and streamed straight back to your device. Each request runs in its own isolated workspace that is deleted the instant the result is returned, so nothing is ever stored or shared.

Frequently Asked Questions

Will my columns split correctly?

Yes — comma and tab separated values are parsed into real spreadsheet columns in the resulting .xlsx.

Are my files uploaded to a server?

Yes. Unlike our browser-based tools, the CSV to Excel runs on our secure server because it needs professional desktop-grade software to do the job well. Your file is processed in an isolated workspace and deleted automatically the moment the result is sent back — nothing is stored, logged or shared.

Is it free? Is there a watermark or size limit?

It is completely free with no sign-up and no watermark. Files up to 100 MB are supported per conversion.
