How the Converter Works
The tool runs a simple, transparent pipeline entirely on your device:
- Load — drop a CSV, TSV, XLSX, XLS or JSON file, or paste CSV/JSON text directly.
- Parse — SheetJS reads the file in your browser. For Excel workbooks, only the first sheet is read, which keeps output predictable for single-sheet rate lists and registers.
- Preview — the first rows are shown as a table so you can verify nothing was mangled before exporting.
- Export — the data is re-encoded as Excel, CSV, TSV or JSON and downloaded. CSV/TSV output applies proper quoting and UTF-8 encoding; JSON output is written as an array of objects using the first row as headers.
Because every step happens in your browser, your data never touches a server — making this safe for rate lists, bank files and commercial registers.
Move Data Between Formats Instantly
Exporters juggle rate lists, shipment registers and portal downloads in CSV, Excel and JSON every day. This tool reads all three — plus TSV — shows you the first rows so you can verify nothing was mangled, then writes the file back out in whichever format you need. Powered by SheetJS, running entirely on your device.
Combine it with the Shipment Tracker to keep registers in your browser, or the HS Code Search to enrich product data before conversion.
How This Converter Is Different From Other Tools
Most online converters ask you to upload a file to their server, then email you a download link. This tool is built differently — for Indian exporters and importers who handle sensitive commercial data. Here’s what makes it different:
- Your data never leaves your device: parsing and conversion run in your browser with SheetJS. No upload, no server, no email link — nothing to leak.
- Built for EXIM workflows: turn portal CSV downloads into neat Excel files, convert rate lists for bulk uploads, and re-format shipment data as JSON for your own systems.
- Instant preview: see the first rows before you export, so you can catch mangled columns or wrong delimiters early.
- Paste or upload: no file handy? Paste CSV or JSON text directly, or load a sample to try it out.
- No signup, no ads, no limits: free forever for personal and commercial use.
- Integrated with EXIM tools: pairs with the Shipment Tracker and HS Code Search for a complete documentation workflow.
