3. Official GSTR-1 Schema Export: Generates a validated GSTR-1 JSON upload payload ready for the official GST Portal offline utility.

Frequently Asked Questions
Can I upload this JSON directly to the GST Portal?
Yes! The JSON format generated matches the official GSTR-1 offline tool schema for B2B invoice tables.
Does this tool calculate reverse charge or cess?
Standard regular B2B supplies with CGST/SGST/IGST are calculated automatically. Reverse charge and special cess can be configured in the invoice item settings.
