What to expect

XML tables use repeated flat records. JSON to XML preserves types using a typed root/item schema; XML attributes use @ and text uses #text in JSON. Spreadsheet formulas are not evaluated; the first sheet is used by default. Review schema and values after conversion.

Do my files leave my device?

No. Thanks to advanced file-processing technology, your files are processed directly on your device, inside your browser. OneKit does not receive your input files or results. Required public processing libraries may download when you first use the tool.
