Questions about xlsx to csv
Does XLSX to CSV change my original file?
No. The original stays untouched; the tool creates a separate result for you to download.
Are my files uploaded to WeCommit?
This tool processes selected files in your browser. Your file contents are not sent to the WeCommit server.
Can I review the result before downloading?
Yes. Tabular tools show a row preview and processing summary. File tools show generated-file details and any limitations.
