Is my GST data uploaded to a server?

No. The conversion runs entirely in your browser using client-side code, so your GST JSON never leaves your device and we never receive or store a copy of it.

Does it work with GSTR-2A and GSTR-2B JSON files?

Yes. Any standard JSON downloaded from the GST portal - including GSTR-2A, GSTR-2B, and GSTR-1 - can be pasted or uploaded and converted to an Excel spreadsheet. The tool reads the JSON structure and lays the records out as rows and columns.

Yes, it is completely free with no signup and no payment. You can convert as many GST JSON files to Excel as you need.

What if my JSON file is large?

Each file can be up to 15 MB, which comfortably covers typical monthly GST return downloads. Long values such as GSTINs and invoice numbers are preserved exactly, with no rounding or scientific-notation corruption. If a period spans several JSON files, convert each one and combine the resulting sheets in Excel.

Convert GST JSON to Excel (GSTR-2A / GSTR-2B)

Last updated: 10 June 2026

Downloaded a JSON file from the GST portal and need it in a spreadsheet? Paste or upload it into our GST JSON to Excel converter online and get a clean Excel file instantly. It is free, needs no signup, and the conversion runs entirely in your browser - so your GST portal JSON file is never uploaded to any server. That makes GSTR-2B JSON to Excel (and GSTR-2A, GSTR-1) a one-step job for reconciliation and filing prep.

Why GST data comes as JSON

The GST portal provides returns data - such as GSTR-2A, GSTR-2B, and GSTR-1 - as downloadable JSON files. JSON is convenient for systems and software to read, but accountants and businesses usually need the same records in Excel to review them, reconcile purchases and input tax credit, and prepare filings. Converting the JSON to a spreadsheet bridges that gap without manual re-typing.

Once the data is in Excel, the usual spreadsheet tools take over: filtering, sorting, lookups, and pivot tables make it straightforward to match purchase records against what the portal reports and to spot mismatches before you file. Keeping a converted copy each period also gives you a simple, auditable trail without depending on a paid accounting add-on.

How to convert GST JSON to Excel

Download the JSON file for your return (for example GSTR-2B) from the GST portal. The file usually arrives with a .json extension, sometimes inside a ZIP - extract it first if so.
Open the JSON to Excel converter and paste the JSON or upload the saved .json file.
Preview the table and download the .xlsx file - ready to open in Excel, Google Sheets, or LibreOffice.

Why this converter fits GST and tax data

Tax data is unforgiving about exactness, and that is where a generic paste-into-Excel approach falls apart. This converter keeps GSTINs and invoice numbers exactly as they appear - no stripped leading zeros and no scientific-notation corruption of long numbers, because long identifiers are preserved as text rather than rounded. Nested JSON is flattened into proper columns you can sort and filter, newline-delimited JSON (NDJSON) is supported, and nothing is uploaded anywhere: the whole process happens in your browser, which matters when the data is financial and tied to your business identity. Because the file stays on your machine, you can convert sensitive returns on a shared or office computer without sending anything over the network. For more on how nesting is handled, see the nested JSON to Excel guide, or the NDJSON / JSONL to Excel guide for line-delimited files.
