PDF to Excel Invoice Extractor – Complete Guide 2026
Manually copying invoice data from PDFs to Excel wastes hours every week. AI-powered PDF to Excel converters can extract NIP numbers, amounts, VAT rates, dates and line items in seconds – with over 95% accuracy. This guide covers everything you need to know.
Why Convert PDF Invoices to Excel?
Finance teams and accountants deal with hundreds of invoices each month. The problem: suppliers send invoices as PDFs, but accounting software needs structured data in Excel or CSV format.
Manual data entry is:
- Slow – an experienced data entry clerk handles ~50 invoices/hour
- Error-prone – 1–3% transcription error rate is industry standard
- Expensive – at PLN 30/hour, processing 500 invoices costs PLN 300+ in labor
An AI PDF-to-Excel extractor like Tablixa processes the same 500 invoices in under 30 minutes at a fraction of the cost.
What Data Gets Extracted from PDF Invoices?
Tablixa extracts the following fields automatically:
| Field | Example |
|---|---|
| Seller NIP (Tax ID) | 1234567890 |
| Buyer NIP | 9876543210 |
| Invoice number | FV/2026/01/001 |
| Issue date | 2026-01-15 |
| Payment due date | 2026-01-29 |
| Line items (name, qty, unit price) | Consulting services, 10h, PLN 200 |
| Net amount per line | PLN 2,000.00 |
| VAT rate per line | 23% |
| VAT amount | PLN 460.00 |
| Gross total | PLN 2,460.00 |
| Payment method | Transfer |
| Bank account number | PL61 1090 1014... |
For Polish invoices, NIP validation is automatic – the extractor flags invalid NIP numbers before export.
How to Convert PDF to Excel in 3 Steps
- Upload your PDF at tablixa.app – drag and drop one or multiple files
- Click Extract – AI processes the document in 5–15 seconds
- Download .xlsx – open directly in Excel, Google Sheets or import to your accounting software
No installation. No account required for the first 3 free conversions (20 with a free account).
Does It Work with Scanned PDFs and Photos?
Yes. Tablixa uses OCR (Optical Character Recognition) combined with AI invoice understanding to handle:
- Digital PDFs (text-layer) – highest accuracy, ~99%
- Scanned PDFs (image-only) – accuracy 95%+ at 300 DPI
- Photos from phone – accuracy 90%+ in good lighting
- JPG and PNG images – same as photos
For poor-quality scans (below 150 DPI, heavy shadows, skewed pages), accuracy drops. Tablixa warns you when confidence is low.
Bulk PDF to Excel Conversion
Processing invoices one by one is still slow. Tablixa supports batch processing:
- Upload up to 50 PDFs at once
- Each invoice is processed in parallel
- Download a single merged Excel file with all invoices as separate rows
- Or download individual files per invoice
This is ideal for:
- Monthly invoice reconciliation
- Onboarding new clients to your accounting system
- Converting archived paper invoices after scanning
PDF to Excel for Polish Accounting
Polish invoices have specific fields that generic converters miss:
- NIP (10-digit tax ID without dashes) – Tablixa validates checksum
- VAT rates: 23%, 8%, 5%, 0%, ZW (exempt), NP (out of scope)
- JPK_VAT fields: mapped automatically if using Comarch Optima or InsERT
- KSeF number: extracted from e-invoices and included in output
Tablixa was built specifically for Polish invoices, so these edge cases are handled correctly.
Connecting PDF to Excel with Comarch Optima or InsERT
Once you have your Excel data, importing to accounting software is the next step:
- Comarch Optima: use the built-in Excel import wizard or generate Tablixa's Optima XML file directly
- InsERT Subiekt GT/Nexo: use Tablixa's EDI++ (.epp) export – no Excel step needed
- Custom ERP: download CSV and configure column mapping
If you're using KSeF, Tablixa can also generate the FA(3) XML file alongside the Excel export – two outputs from one PDF upload.
API Access for Developers
For companies processing thousands of invoices, Tablixa offers a REST API:
POST /api/extract
Content-Type: multipart/form-data
Authorization: Bearer <api_key>
file: invoice.pdf
format: excel
The response includes a download URL for the Excel file and structured JSON with extracted fields.
