How the Converter Works

The tool runs a simple, transparent pipeline entirely on your device:

  1. Load — drop a CSV, TSV, XLSX, XLS or JSON file, or paste CSV/JSON text directly.
  2. 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.
  3. Preview — the first rows are shown as a table so you can verify nothing was mangled before exporting.
  4. 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:

Frequently Asked Questions

Which file types can I convert?
CSV, TSV, Excel (XLSX and older XLS) and JSON. Output options are Excel, CSV, TSV and JSON. Multiple sheets: only the first sheet is converted.
Is my data uploaded anywhere?
No. All parsing and conversion happens in your browser with SheetJS. Files never leave your device, making this safe for sensitive commercial data.
Can I paste data instead of uploading a file?
Yes. Paste CSV text or JSON into the paste box and click Parse Pasted Text — the same preview and export options then apply.
How does the converter handle Excel files with multiple sheets?
Only the first sheet of an Excel workbook is read and converted. This keeps the output predictable for rate lists and shipment registers, which are usually single-sheet files.
Is the CSV, Excel & JSON Converter free to use?
Yes. The CSV, Excel & JSON Converter is 100% free for personal and commercial use — no registration, login or payment required.
