Questions about data & document converters
Do I need Microsoft Office to convert Word or Excel files?
No. Word (.docx) and Excel (.xlsx) files are read and written directly in your browser.
What happens to nested JSON when converting to CSV or Excel?
Nested objects are flattened into dotted column names (address.city), and arrays are kept as JSON text in their cell.
Are my files uploaded?
No. All document and data conversions run locally in your browser.
