Hello @nish-thinkify-io,
Thank you for posting here in the Community. I can help you fix the JSON file issue in QuickBooks Online.
When exporting a JSON file, you usually encounter an issue if there is missing or incorrect information. Each error message has different instructions on how to resolve and export data successfully from QuickBooks.
If you're getting the Invalid company GSTIN error, I recommend providing the registration number you have received in the GST Registration Certificate.
Here's how:
- In the left navigation bar, click Taxes.
- Select GST from the Tax dropdown.
- Click Edit GST and then Edit settings.
- Enter your GSTIN and click Save.
In case its a different error, I recommend you visit the JSON errors in GSTR1, GSTR3B article. It contains detailed instructions about how to fix each possible errors you may encounter during the process.
Additionally, I recommend visiting the following article to learn more about the steps to acquire GSTR1 data in QuickBooks: How to export QuickBooks data for GSTR1.
