A premium desktop utility designed to convert offline JSON files downloaded from the GST portal for outward supplies (GSTR-1) into structured, client-ready Excel sheets.

Privacy & DPDP Compliance: Operates 100% locally and offline directly in RAM. Uploading GSTR JSON files containing client invoices, supplier names, PANs, and GSTINs to online converters is a severe breach of data privacy; this local tool eliminates that liability.

Key Features:

• Extracts transaction records across all outward tables (B2B, B2CL, B2CS, CDNR, EXPORT, etc.).
• Automatically creates a consolidated workbook containing separate sheets for each table and an aggregated master sheet (effcorp_all_combined).
• Supports bulk file processing in a single run.
• Maps technical JSON fields into clean, user-friendly column headers.
