What is an Invoice Parser?
An invoice parser reads scanned bills, photographed receipts, and PDF invoices and turns them into structured rows your finance team can actually work with. Instead of typing 30 invoices into Tally or Excel by hand, you drop them into the parser and pull out the supplier name, GSTIN, invoice number, date, line items, quantities, rates, GST splits, and grand total.
This tool runs Tesseract.js — a WebAssembly build of the open-source Tesseract OCR engine — entirely inside your browser. Pages are converted to text on your machine, then a set of GST-aware regular expressions pulls out the fields finance cares about: 15-digit GSTINs, invoice numbers, dates in any common Indian format, CGST/SGST/IGST values, HSN/SAC codes, and item-level quantities and prices.
Because nothing is uploaded, you can parse vendor invoices, customer bills, expense receipts, and reimbursement claims without sending sensitive financial data to a third-party API. Export the result as CSV and import straight into your accounting software, ERP, or Google Sheets.
Why use this Invoice Parser
Built for Indians, by Indians. Every number, every formula, every slab — tuned to FY 2026-27 reality.
Image + PDF support
Upload JPG, PNG, WebP, or PDF — multi-page PDFs are rendered and OCR'd page by page.
GSTIN auto-detect
Recognises the 15-character GSTIN format and pulls both supplier and buyer GSTIN where present.
Line item extraction
Detects qty × rate × amount rows and HSN codes so each line of the invoice becomes a CSV row.
Tax + total breakdown
Pulls subtotal, CGST, SGST, IGST, cess, round-off, and grand total — labelled and ready for reconciliation.
100% private
OCR runs in your browser via WebAssembly. Files never leave your device. No login, no upload, no API.
One-click CSV
Export the extracted invoice and line items as a flat CSV ready for Excel, Tally import, or Google Sheets.
Using the Invoice Parser in 4 steps
No onboarding, no signup. Answer three fields and the numbers update live.
Upload an invoice
Drag a JPG, PNG, or PDF onto the drop zone. PDFs with multiple pages are processed page by page.
Wait for OCR
Tesseract loads the English language model on first use (~5 MB) and reads the document. Clear scans take 5–15 seconds.
Review extracted fields
Check the supplier name, GSTIN, invoice number, date, line items, taxes, and totals. Edit any field inline if needed.
Export to CSV
Hit "Download CSV" to save a flat file with the header fields and one row per line item — ready for finance.
Tips to get the most out of it
Higher resolution = better OCR. Aim for at least 300 DPI scans. Phone photos work but flatten the page and avoid shadows.
Cropped, deskewed images parse far more accurately than full-desk photos. Trim borders before uploading where you can.
Always sanity-check the GSTIN against the GSTN portal — OCR can confuse the digits 0/O and 1/I/l in poor scans.
Process invoices in batches of 5–10 rather than one giant PDF. Browser memory and the WebAssembly OCR engine perform better on smaller jobs.
For non-standard invoice templates, the line-item table may need manual fixes. The parser shows the raw OCR text below the structured view so you can copy-paste anything missed.
Real-world scenarios
How Indians actually use this parser — concrete inputs, concrete outcomes.
Vendor bill into Tally
A 3-page vendor PDF with 12 line items is parsed in 18 seconds. Supplier GSTIN, invoice number, HSN codes, and CGST/SGST splits all populate the table. CSV exported and imported into Tally as a purchase voucher with zero retyping.
Expense reimbursement processing
Finance receives 40 reimbursement receipts from sales staff at month-end. Each is dropped into the parser, totals verified, and exported. A morning of data entry becomes a 30-minute review session.
GSTR-2A reconciliation prep
Vendor invoices are parsed and exported, then cross-checked against the GSTR-2A register to spot suppliers who haven't filed their GSTR-1 yet. Mismatches are flagged before ITC is claimed.
Frequently Asked Questions
Still have a question? Our team replies within a business day.
No. The OCR engine (Tesseract.js) runs entirely in your browser as WebAssembly. The image or PDF you upload is processed locally — nothing is sent to a server. You can verify this by parsing an invoice with your network tab open.
JPG, JPEG, PNG, WebP, and PDF. PDFs are rendered page-by-page using PDF.js and each page is OCR'd separately. Scanned PDFs (image-based) are supported; native text PDFs work even faster since text is read directly without OCR.
For a clean printed invoice or a high-resolution scan, accuracy on key fields (GSTIN, invoice number, total) typically exceeds 95%. Line items in tabular form are usually 85–95% accurate. Phone photos with shadows or skew can drop below 80% — always review before exporting.
Yes — you can upload a multi-page PDF, but the parser treats each upload as one invoice and concatenates pages. For multi-invoice PDFs, split them first or process each in turn.
Currently the tool loads the English language pack only. Hindi, Tamil, and other Indian-language invoices will OCR poorly. Most B2B Indian invoices are in English so this rarely matters in practice.
Yes. Every extracted field is editable inline. If the parser misreads a digit in the GSTIN or misses a line item, you can fix it before downloading the CSV.
The CSV uses standard column headers (supplier_name, gstin, invoice_number, date, item, qty, rate, amount, cgst, sgst, igst, total). Most accounting software accepts this format directly via their CSV import wizards.
On the first upload, the browser downloads the Tesseract English language model (~5 MB) and the WASM engine. Subsequent parses reuse the cached model and run in 5–15 seconds for typical invoices.
