No. ToolFlow processes a temporary server-side copy and returns a new result. Your original local file is not changed.

What powers JSON 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.
