Generate JSON file using GST Offline Tool and upload on the portal
Instead of directly generating a JSON file from TallyPrime, you can also make use of the GST Offline Tool provided by the portal. In this method, you have to export your GSTR-1 details from TallyPrime in the MS Excel or CSV format, and then import the file into the GST Offline Tool. Then you can export the details to a JSON file and upload it to the portal.
File GSTR-1 directly on the portal
If you do not wish to file your return using a JSON file, then you can also file your GSTR-1 directly on the portal. In this method, you can easily copy the details from the GSTR-1 report in TallyPrime and paste it in the respective sections on the portal. Alternatively, you can also fill the details manually by referring to the values in TallyPrime.
