DataForge is a browser-based spreadsheet and data converter. It transforms data between CSV, TSV, XLSX, XLS, JSON, and XML formats with a live data preview. All processing is client-side.

1. Upload a data file (CSV, TSV, XLSX, JSON, XML) 2. Preview the data in the table view 3. Select an output format 4. Click Convert/Download

CSV → XLSX, TSV, JSON, XML
TSV → XLSX, CSV, JSON, XML
XLSX/XLS → CSV, TSV, JSON, XML
JSON → CSV, TSV, XLSX, XML
XML → CSV, TSV, XLSX, JSON

• Data preview table after upload
• Multi-sheet support for Excel files
• Auto-detect input format
• One-click convert and download
• File info display (name, size)

• JSON should be an array of objects for best CSV conversion
• Use TSV instead of CSV if your data contains commas
• XLSX output preserves data types (numbers, dates, text)
• Preview helps catch data issues before converting

Preview empty: The file may be empty or in an unsupported encoding.
Wrong columns: CSV files with inconsistent delimiters may parse incorrectly.
Large file slow: Files over 20MB may take time. Processing is local.
