PDF Data Extraction
Upload PDF, Word, Excel or email files and receive structured data as Excel, CSV, JSON or UBL. Process up to 10 files at once. Six extraction types: invoices, floor plans, forms, tables, emails and legal documents.
What do you need to extract?
Choose the type of data you want to pull from your PDFs.
Floor Plan
Extract room names, dimensions, and areas from architectural drawings and blueprints.
Invoice
Extract line items, totals, tax amounts, and vendor information from invoices.
Form
Extract field names, values, checkboxes, and sections from filled-in forms.
Extract sender, recipients, subject, and body from archived emails.
Table
Extract tabular data with automatic header detection and data typing.
Legal Documents
Analyse contracts and agreements: parties, clauses, key terms, and risk flags.
Custom
Define your own extraction rules with AI-powered prompts.
How it works
Three steps from document to structured data.
Upload your files
Upload PDF, Word, Excel or email files. Up to 10 files at once, maximum 50 MB per file.
Automatic analysis
The document is analysed and relevant fields are detected. Email files are parsed directly, other document types are processed visually.
Download structured data
Export as Excel, CSV, JSON or UBL. Each file type returns the fields specific to that document type.

Frequently asked questions
What file types can I upload?
You can upload PDF, Word (.doc, .docx), Excel (.xls, .xlsx) and email files (.eml, .msg). Word, Excel and email files are automatically converted for processing. Email files are parsed directly without conversion. Up to 10 files at once, maximum 50 MB per file.
How accurate are the results?
It depends on the extraction type. Email extraction is 100% accurate because files are parsed directly. PDF forms with built-in fields (AcroForm) are also 100% accurate. For visual extraction (invoices, tables, legal), each extracted field includes a confidence score (high/medium/low) so you can see where manual review may be useful.
What languages are supported?
Visual extraction works with documents in all common languages, including Dutch, English, German, French and Spanish. Extracted data fields are standardised regardless of the source language. Email extraction is language-independent.
What does data extraction cost?
Costs vary by extraction type. PDF forms with AcroForm fields cost 1 credit. Invoices and tables cost 2 credits per PDF (3 per Word/Excel file). Legal documents cost 3 credits per PDF (4 per Word file). Emails cost 2 credits per file. New users receive 15 free credits on registration.
Can I automate extraction through an API?
Yes. Via the REST API you can submit files and receive structured results as JSON. Webhooks notify you when processing is complete. The API supports all six extraction types and all file formats.
