What is a GST error report?
When a GSTR-1 upload fails or partially fails, the official GST portal generates an error report listing every rejected record and the reason. Most failures come from a duplicate invoice number, an invalid GSTIN, or the wrong return period — this tool reads the file so you can see exactly what to fix.

Frequently asked questions
What is a GST error report?
A GST error report is a JSON file the GST portal generates when a GSTR-1 upload fails or is only partially accepted. It lists each record the portal rejected along with the reason, so you can fix the data and upload again.
When is a GSTR-1 error report generated?
The portal generates an error report after you upload a GSTR-1 JSON and processing fails or partially fails. Once the status shows errors, you can download the error report JSON from the GST portal and open it in this viewer.
What file types can I upload to the error report viewer?
You can upload the error report as a .json file or as a .zip archive that contains the JSON. Each file must be 1MB or smaller, and you can upload more than one file at a time.
Does the tool read the error_report section?
Yes. The viewer reads the error_report section of the file, then shows the error message and the rejected records for each GSTR-1 section in a clean, scrollable table so you can see exactly what to fix.
Is my data safe when I use the error report viewer?
Yes. Everything runs locally in your browser. Your error report files are never uploaded to or stored on any server, so your GST data stays on your own device.
How do I fix common GSTR-1 errors?
Read the error message for each section, then correct the matching record in your accounting software — common fixes include an invalid GSTIN, a duplicate invoice number, or a wrong tax or place-of-supply value. Re-generate the JSON and upload GSTR-1 again.
