常见问题解答

Does this handle large spreadsheets?
It works well for typical spreadsheets, but very large files (tens of thousands of rows) may take longer to process since everything runs in your browser rather than on a server.
What happens to formulas in an Excel file?
Only the calculated values are preserved — formulas themselves are not carried over to CSV or JSON output.
Can I convert JSON that isn't a flat list of objects?
Best results come from a JSON array of similarly-shaped objects (like API responses or database exports) — deeply nested JSON will be simplified when flattened into rows.
