AI Invoice Extractor

Extract key information from invoices using pattern recognition. Supports digital and text-based invoices.

100% LOCALOCR supportLine itemsMulti-currencyAuto-parse
🧾
1. Provide your invoice
Paste invoice text or upload a PDF/TXT file. The extractor identifies vendor name, invoice number, dates, amounts, tax, and line items automatically.
🔍
2. Pattern recognition extracts data
The engine uses regex patterns to find standard invoice fields (Vendor, Invoice #, Date, Due Date, Total, Tax) and parses line items from the text.
📊
3. Review extracted data
See a structured breakdown of all invoice fields with a line items table showing description, quantity, unit price, and amount.
💾
4. Export as CSV or text
Download the extracted data as a CSV file for import into accounting software, or copy it as formatted text.
💡 Tips
Works best with standard invoice formats containing labeled fields like "Invoice No:", "Total:", "Due Date:".
For scanned image invoices, OCR is not yet supported — please paste the text content instead.
Line items are detected by looking for lines with currency amounts ($, €, £).
For scanned image invoices, upload PNG/JPG files — OCR will extract text automatically using Tesseract.js.

How an invoice becomes structured data — illustrated

Extraction is a pattern-recognition pipeline with an optional AI upgrade. The engine scans your invoice — pasted text, a PDF, or a scanned image (OCR via Tesseract.js) — and applies labeled-field regex patterns to find vendor, invoice number, dates, totals, and tax. It then isolates candidate lines that contain currency amounts to build the line items. When a local LLM is loaded, the same raw text is passed to the model for more robust parsing; otherwise the deterministic pattern engine stands in.

Text, PDF, or scanned image enters; a structured invoice object (with line items and totals) comes out, ready for CSV or accounting export.

One PDF, six fields, zero typing — Priya's monthly books

Priya is reconciling her monthly spending. She uploads the CloudHosting invoice PDF and lets the extractor pull out the vendor, dates, totals, and every line item before exporting to her accounting software.

  1. Input:CloudHosting_Invoice.pdf — a standard one-page PDF with labeled fields
  2. Fields:Vendor "CloudHosting Inc." · Invoice # INV-2026-0147 · issue & due dates · total $129.90 · tax $10.40
  3. Line items:Three currency lines become items — web hosting, domain renewal, and support — each with qty, unit price, and amount
  4. Export:Priya downloads the accounting CSV and confirms the batch total matches her statement before approving it

To extract invoice data: upload your invoice image or PDF — the AI reads vendor, date, amounts, line items, and tax, outputting structured JSON or CSV.

What Is the AI Invoice Extractor?

The AI Invoice Extractor turns invoice PDFs, images, or pasted text into structured data you can actually use. Feed it one file or a batch and it pulls out the vendor name, invoice number, issue and due dates, total and tax amounts, currency, line items with quantities and prices, and a payment status. Scanned invoices are handled too: Tesseract-based OCR runs in your browser to read image files before parsing begins. An optional local AI model improves messy layouts and line-item accuracy, with pattern recognition always available as a fallback. Results can be exported as a standard CSV, a formatted text report, or an accounting-ready CSV with debit and credit columns.

Who Should Use This Tool?

Freelancers and small agencies use it to digitize supplier bills without paying for an enterprise document platform. Bookkeepers and accountants process the monthly invoice pile in batch mode, which shows per-file progress and flags duplicate invoices automatically. Finance teams at startups reconcile expenses and hand clean CSV exports straight to QuickBooks, Xero, or a spreadsheet. Office managers who receive scanned receipts and photos of paper invoices benefit from the built-in OCR step. Because every file is parsed on the local machine, it also fits practices handling client billing records they cannot legally upload to a third-party cloud service.

How Does It Work?

(1) Choose an input mode: upload a single file, paste raw invoice text, or switch to batch and select many files at once. (2) Run extraction. A scan overlay walks through the stages: reading the document, locating the vendor and invoice number, finding dates and payment terms, then parsing amounts and line items. If no AI model is loaded, the tool says plainly that it is using pattern-based extraction and offers to load one for better accuracy. (3) Review the structured result, including the detected currency (US dollars, euros, or pounds) and itemized lines. (4) Export to CSV or accounting format, or route the invoice through the approval panel with an assignee and notes.

What Can I Do with the Extracted Data?

The headline output is an accounting workflow. The standard CSV lists every field, including vendor, number, dates, totals, tax, and currency, in columns a spreadsheet opens cleanly; the accounting export goes further, breaking line items into debit and credit rows that match double-entry bookkeeping. In batch mode you also get rollups by currency and by vendor, so a stack of receipts becomes a spend summary without extra formulas. Each invoice can be marked pending, paid, or flagged for review, and the approval panel lets you assign a reviewer and attach notes, turning raw extraction into a lightweight audit trail. Fields stay editable, so you can correct any misread value before exporting.

Frequently Asked Questions

What specific data fields does it extract from invoices?

It extracts: vendor name and address, invoice number, issue date, due date, subtotal, tax amount (with rate), total amount due, payment terms, and individual line items (description, quantity, unit price, extended price). Output is structured JSON or CSV, ready for import into QuickBooks, Xero, or FreshBooks accounting software.

Can I batch-process multiple invoices at once?

Yes. Upload multiple invoice PDFs or images, and the tool processes each sequentially, extracting all fields and compiling results into a single CSV export. A batch of 20 invoices processes in 2-4 minutes. This eliminates manual data entry that typically takes 3-5 minutes per invoice—saving 1-2 hours for a 20-invoice batch.

Does it upload my financial documents?

No. OCR (Tesseract.js) and data extraction run entirely in your browser. Invoice images and extracted data never leave your device. This is critical for accounting firms handling client financials under confidentiality agreements and businesses subject to SOC 2 or PCI-DSS data handling requirements.
