Prepare GSTR-1 details offline and generate an upload-ready JSON file with Snexa.
Quick Answer: How to Generate a GSTR-1 JSON File
To generate a GSTR-1 JSON file, enter or import your outward supply details in a compatible GSTR-1 preparation tool, review invoice information such as GSTIN, invoice number, date, taxable value and tax amounts, then use the tool’s JSON export or generate-file option. After that, log in to the GST portal, open the relevant GSTR-1 return period and use the Prepare Offline or applicable upload option to upload the generated JSON file.
Note about “5 minutes”: You may create the JSON file quickly when invoice data is already prepared and verified. The total time can be longer if you need to collect invoices, correct GSTINs, classify transactions, reconcile sales records or handle a large number of entries.
What Is a GSTR-1 JSON File?
A GSTR-1 JSON file is a structured digital file containing outward supply details that can be uploaded to the GST portal. It organizes return information in a standard format so that invoice and summary data can be imported instead of being entered line by line on the portal.
Businesses commonly generate GSTR-1 JSON files when they have multiple B2B invoices, B2C sales, credit notes, debit notes, HSN summary details or document-summary information to prepare. The GST portal supports offline preparation and JSON-file upload through the GSTR-1 return workflow.
Why Generate GSTR-1 JSON Instead of Entering Every Invoice Online?
Prepare multiple invoices locally before uploading data to the portal.
Check invoice details before the data is uploaded for filing.
A practical workflow for businesses and professionals handling many invoices.
Prepare and review data before opening the GST portal for upload.
What You Need Before Generating GSTR-1 JSON
- GSTIN: Your valid GST registration number.
- Return period: The correct month or quarter for which GSTR-1 is being prepared.
- Sales and invoice records: B2B, B2C, export, credit-note, debit-note and other applicable outward supply details.
- Recipient GSTIN: Required where applicable, especially for B2B invoice reporting.
- Tax details: Taxable value, GST rate, CGST, SGST, IGST and cess information where applicable.
- HSN or SAC details: Prepare the applicable HSN or SAC summary according to your reporting requirements.
- Compatible GSTR-1 tool: Use a compatible offline utility, accounting system or GSTR-1 preparation tool capable of creating the required JSON output.
