GSTR-1 JSON to Excel Converter

Convert your complicated GSTR-1 JSON files directly into readable Excel spreadsheets. 100% Free and works completely inside your browser. No data is uploaded to our servers.

Complete Guide: How to Convert GSTR-1 JSON to Excel Without Uploading

The Goods and Services Tax Network (GSTN) generates return backup files and ERP exports exclusively in JSON format. While JSON is ideal for automated server communication, human reviewers, tax auditors, and accounting teams cannot easily inspect invoice line items, tax heads, or customer GSTINs in raw JSON code.

Our GSTR-1 JSON to Excel Converter solves this problem by parsing all nested JSON return arrays directly inside your web browser and compiling them into structured, multi-sheet Excel (.xlsx) workbooks matching the official GST portal return tables.

Step-by-Step: How to Download & Convert GSTR-1 JSON

  1. Log in to the GST Portal: Navigate to gst.gov.in > Services > Returns > Returns Dashboard.
  2. Select Financial Year and Return Period: Choose the applicable quarter/month and open GSTR-1.
  3. Download JSON: Under the Download tab, click Generate JSON File to Download. When ready, click the generated link to save the .json file to your computer.
  4. Upload to Taxzentic: Select or drag-and-drop the downloaded JSON file into the converter box above.
  5. Instant Excel Download: Click Convert to Excel. Your structured .xlsx workbook downloads immediately with separate sheets for B2B, B2CL, B2CS, CDNR, EXP, and HSN summary.

100% Client-Side Privacy Guarantee

Invoice numbers, buyer GSTINs, and commercial transaction totals contain strictly confidential financial data. Unlike cloud converters that upload your financial files to third-party servers, Taxzentic processes your GSTR-1 file entirely inside your local browser runtime using the JavaScript FileReader API and SheetJS library. Zero bytes of invoice data leave your computer.
