Frequently Asked Questions
What is a GSTR-1 JSON file?
A GSTR-1 JSON file is the standard format used by the GST portal and offline tools to export your GSTR-1 return data. It contains all outward supply details including B2B, B2C, export, and credit/debit note information.
Is my data safe with this tool?
Yes. This tool runs entirely in your browser. Your JSON file is never uploaded to any server. All processing happens locally on your device.
Can I upload a ZIP file?
Yes. If the GST portal gives you a ZIP file containing the JSON, you can upload the ZIP directly. The tool will automatically extract the JSON from inside.
Which sections are included in the Excel output?
The converter creates separate sheets for B2B, B2CL, B2CS, CDNR, CDNUR, EXP, HSN, DOC, NIL, AT, and ATADJ — covering all sections of the GSTR-1 return.
Do I need to sign up or pay?
No. This is a completely free tool with no signup, no login, and no limits on usage.
