FAQ

Are my spreadsheets uploaded?

No. CSV, JSON and XLSX files are parsed in your browser worker, and the download is generated locally.

Does it preserve Excel formulas and formatting?

No. This tool converts the visible values from the first worksheet into a clean table. It does not calculate formulas or preserve cell styling.

How is JSON converted to a table?

Arrays of objects become rows, object keys become columns, and nested object keys are flattened with dot paths. Arrays of arrays are kept as table rows.
