Frequently asked questions
What happens to nested objects and formulas?+
Nested objects and arrays are serialized into individual CSV cells. Formula-like cells receive an apostrophe when spreadsheet protection is enabled; disable it only when literal CSV text is required.
Are my files uploaded?+
No. Processing happens on this device. The tool may download its own code, but source files and output are not sent to a processing server.
