Excel to CSV / JSON

XLSX / XLS

Excel to CSV / JSON converts MS Excel worksheets (.xlsx, .xls) into clean CSV data sheets or JSON array nodes. The client-side parser uses SheetJS to decode binary spreadsheets, extract cell matrices, and format tabular rows offline.

Frequently Asked Questions

Can I convert multi-sheet Excel files?

By default, the tool converts the first sheet of the uploaded workbook. You can export it as a clean CSV table or a structured JSON array.

Are Excel formulas preserved?

The parser reads the computed static values of cells rather than dynamic cell equations, ensuring output CSV/JSON has correct content.
