Turn the GST return JSON exported from the GST portal or the GST offline tool into clean CSV files. Upload your GSTR-1, GSTR-2A, GSTR-2B or GSTR-3B file and download the data ready to open in any spreadsheet, database or accounting tool.

Which GST returns are supported?

  • GSTR-1 - outward supplies (B2B, B2C Large, B2C Small, Credit/Debit Notes, Exports, HSN Summary, Documents Issued).
  • GSTR-2A and GSTR-2B - inward supplies and purchase reconciliation.
  • GSTR-3B - the summary return.

The return type is detected automatically, so you do not need to choose the form.

How are the CSV files organised?

A GST return holds several sections, and a single CSV cannot hold them all, so the result is a .zip with one CSV file per section. Each CSV has one row per invoice line and clear column headers (Counterparty GSTIN, Invoice No, Invoice Date, Taxable Value, IGST, CGST, SGST/UTGST, Cess), with Place of Supply shown as the state name and amounts kept as numbers.

Prefer a single workbook with a tab per section? Use our GSTR JSON to Excel converter instead.

Convert many returns at once

Put the return files into a single .zip (or .tar.gz) and upload it - each file inside is converted. Converting an archive of multiple files needs a free account, so sign up and confirm your email first. To convert a single return, upload the .json directly.

Is my GST data kept private?

Yes. Every file uploaded to our service is encrypted and automatically deleted after 24 hours. Your tax data is never shared.
