Free XLS to CSV converter

AnyConv365 helps you convert XLS files to CSV without installing software. Open this page, choose your file, and download the result.

CSV is the lingua franca for imports and scripts. Export from Excel when a pipeline needs plain rows; convert back to XLSX when you need filters and formatting again.

How it works

Is XLS to CSV conversion free?

Yes. AnyConv365 lets you convert XLS to CSV online for free with no account required.

Will my file quality be preserved?

We aim for the best practical fidelity for each pair. Preview the download before sharing when quality is critical.

Do you store my files?

Server-side source files are deleted immediately after a successful conversion. If conversion fails, the source file is retained for up to one hour for error diagnosis and then deleted automatically.

Do CSV files keep Excel formulas?

No. CSV stores values only. Keep an XLSX/ODS copy when calculations still matter.

Which sheet exports from .xls?

CSV is one table. Export usually uses the first sheet — split multi-sheet workbooks if needed.

What to check

Privacy: Server-side source files are deleted immediately after a successful conversion. If conversion fails, the source file is retained for up to one hour for error diagnosis and then deleted automatically.

  1. 1 Compare the result with the original before deleting or sharing anything.
  2. 2 Check content, layout, timing, fonts, or folder structure that matters to your workflow.
  3. 3 Keep the source file as a backup because some format-specific features cannot transfer.
