CSV stores values only — keep XLSX when formulas and formatting still matter.
How it works
Is XLSX to CSV conversion free?
Yes. AnyConv365 lets you convert XLSX 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 is exported to CSV?
CSV is a single table. Export usually focuses on the active/first sheet — split workbooks first if you need every sheet.
