Common questions

Is this CSV to Excel converter free?

Yes. The local converter is available without an account or per-file charge.

Are my files uploaded?

No. Supported conversions run locally on your device using browser APIs and WebAssembly.

Will complex formatting look identical?

Text and document structure are preserved where possible. PDFs use layout-aware reconstruction and automatic local OCR for scanned pages, though very unusual fonts or visual layouts can still differ.
