Free GSTR-1 Excel Utility for E-Commerce Sellers
Why use this Online GST Tool?
Filing GST returns as an online seller on platforms like Amazon, Flipkart, Meesho, and Myntra can be complicated. Most sellers struggle with converting the raw Excel/CSV reports provided by these marketplaces into the specific GSTR-1 JSON format required by the government portal.
- Zero Cost: Unlike paid software like ClearTax or Tally, our tool is 100% free.
- Privacy First: No data is uploaded to our servers. All conversion happens locally in your browser.
- Multi-Platform: Merge sales data from Amazon FBA, Flipkart Smart Fulfilment, and Meesho into one return.
How to File GSTR-1 using this Tool
Follow this simple step-by-step guide to file your GSTR-1 return without error:
- Download Reports: Log in to your seller panels (Amazon Seller Central, Flipkart Seller Hub, etc.) and download the "Merchant Tax Report" or "Sales Report" for the return period.
- Upload Files: Drag and drop the Excel or CSV files into our GST converter tool above. You can upload multiple files at once.
- Select Platforms: Ensure each file is mapped to the correct platform (e.g., set "Amazon" for Amazon files). If you have a custom format, use the "Custom Excel" option to manually map columns like Invoice Number, Taxable Value, and IGST.
- Generate JSON: Click "Generate GSTR-1". The tool will process B2B, B2CS, and CDNR transactions, calculating the correct tax liability.
- Upload to GST Portal: Download the JSON file and upload it to the GST Portal under Returns Dashboard > GSTR-1 > Prepare Offline > Upload.

- 4A, 4B, 4C, 6B, 6C (B2B): Supplies made to registered GSTINs.
- 7 (B2C Others): Supplies to unregistered consumers (inter-state value > 2.5L and all other intra-state).

Common GST Filing Errors We Fix
Manual filing often leads to mismatch errors. Our tool automates:
- Place of Supply Formatting: Automatically converts state names (e.g., "Maharashtra") to GST state codes (e.g., "27-Maharashtra").
- Decimal Rounding: Rounds tax amounts to 2 decimal places to prevent JSON validation errors.
- Negative Values: Correctly handles credit notes and returns which are often represented as negative values in platform reports.
