CSV to XLSX FAQ
Does CSV to XLSX overwrite my original file?
No. ToolFlow processes a temporary server-side copy and returns a new result. Your original local file is not changed.
What powers CSV to XLSX?
This tool uses ToolFlow’s local Python document stack, including open-source document libraries installed on the hosting account. It does not send the document to a third-party conversion API.
Privacy and file handling
Uploaded files are processed in temporary server storage. ToolFlow attempts to delete temporary source and output files after processing or delivery. Do not upload material you are not authorized to process. See the Privadesa for details.
