Why OkayGST is India's Leading GST Tool for E-Commerce & GST JSON File Generator
Purpose-built for online sellers and chartered accountants who need error-free GSTR-1 & Meesho JSON exports without Excel offline tool crashes.
Dedicated Meesho JSON Generator
Generating a clean Meesho JSON file is notoriously difficult due to negative turnover from customer returns, exchanges, and TCS discrepancies. OkayGST automatically offsets return credits against forward sales per state and tax slab, guaranteeing 100% portal acceptance.
Direct GST JSON File Generator
Bypass the government Excel offline utility completely. Our lightning-fast GST JSON file generator compiles Tables 4 (B2B), 7 (B2CS), 9B (Credit Notes), 12 (HSN Summary), and 14 (E-Commerce Supplies) into a pre-validated, schema-compliant file ready for 1-click portal upload.
Engineered GST Tool for E-Commerce
Standard accounting packages fail with marketplace edge cases. As India's leading GST tool for e-commerce, OkayGST handles Section 52 TCS reconciliation, multi-state Amazon FBA inventory across 6 GSTINs, and automatic sister-order HSN recovery for return credit notes.

Pre-flight validation automatically isolates problematic records: invalid buyer GSTINs, mismatching tax rates, negative taxable values, and POS 00 errors into an interactive batch resolution queue.
