The invoice problem

Automate Invoice Data Extraction Without Manual Data Entry

One invoice is easy to handle manually. Dozens or hundreds of invoices from different suppliers, layouts and formats are not.

Invoice data extraction lets you retrieve the values your process actually needs and organize them as structured fields, instead of repeatedly searching and copying information document by document. If you are deciding when that switch is worthwhile, our comparison of manual data entry and automated document extraction looks at the trade-offs in more detail.

Invoice fields

Start with suggested fields. Change anything you need.

Select Invoice as the document type and use Heyyel Data Extractor's suggested fields as a starting point. Keep them, remove them or add fields specific to your business. For documents that need a completely different schema, Custom Data Extraction lets you define the structure from scratch.

Your structure

Not every team needs the same invoice information

A fixed invoice parser may give every company the same schema. Heyyel Data Extractor lets the extraction structure reflect the way your team actually uses invoice data.

01

Use standard fields

Supplier, invoice number, date, tax, total, line items and more.

02

Add business-specific fields

Project code, contract number, cost center, delivery location or internal reference.

03

Keep the result structured

Use text, numbers, dates, arrays and nested information where needed.

Project reference Cost center Department Payment terms

Different suppliers, same information

Extract Invoice Data Across Different Supplier Layouts

Supplier A may place the invoice number at the top. Supplier B may put it beside the billing address. Supplier C may use a different table structure entirely. Heyyel Data Extractor can extract the same invoice fields across different supplier layouts without requiring a fixed template for every document format.

Supplier layout A

Invoice information grouped in a traditional header and line-item table.

Supplier layout B

Different positioning, same invoice fields to retrieve.

Supplier layout C

Another design without rebuilding your extraction goal around the page.

Structured outputs

From Invoice PDF to Structured JSON or CSV

Once the requested values are identified, the result can be used outside the original invoice. If your main challenge is selecting only a handful of fields from a PDF, the guide on extracting specific data from PDF documents explains that workflow in more depth.

Invoice to JSON

Use structured JSON when invoice data needs to feed an application, database, API or automated workflow.

{
  "supplier": "Northstar Ltd.",
  "invoice_number": "INV-10582",
  "invoice_date": "2026-08-18",
  "tax": 240.00,
  "total": 1440.00,
  "currency": "EUR"
}

Invoice data to CSV

Export selected invoice fields to CSV when the data needs to be reviewed or used in a spreadsheet workflow.

Invoice OCR

Invoice OCR for Structured Data Extraction

Invoice OCR is useful when invoices arrive as scans or image-based PDFs. But recognizing the text is only part of the job.

With Heyyel Data Extractor, OCR supports the invoice extraction process so the final result is organized around selected invoice fields rather than leaving you with text you still need to search manually. The distinction between the two steps is explained in our guide to OCR vs data extraction.

Invoice Data Extraction Software Built Around Your Workflow

Heyyel Data Extractor combines invoice OCR and structured data extraction in one tool. Instead of returning only raw text, the software extracts the invoice fields you select and organizes them into structured JSON or CSV output.

Invoice processing automation

Automate Invoice Processing with Structured Data Extraction

Manual invoice processing often starts with the same task: locate values in the document and enter them somewhere else. Structured invoice extraction reduces that repetitive step.

Manual invoice handling

1

Open each invoice

Find the right page and locate the required values.

2

Copy the information

Move supplier, date, tax, totals and line items manually.

3

Repeat

Perform the same work again for the next invoice.

With invoice data extraction

1

Choose the invoice fields

Start from suggested fields or adapt them to your workflow.

2

Extract structured values

Process the document around the invoice information you selected.

3

Use the output

Review and export invoice information as JSON or CSV.

Different teams, different fields

One invoice can serve several workflows

Accounting

Focus on the financial and supplier information needed for invoice review.

Supplier
Invoice number
Invoice date
Tax & total
Currency

Procurement

Retrieve purchasing details and repeated line-item information.

Purchase order
Supplier
Products
Quantities
Unit prices

Operations

Add business-specific information beyond standard invoice fields.

Project reference
Department
Service period
Delivery details
Internal codes

Finance teams rarely work with invoices alone. If the same workflow also handles purchase proofs or account activity, the extraction approach can be extended naturally to receipts and bank statements. If you are still comparing approaches or vendors, the invoice data extraction software comparison looks at different types of tools and the workflows they fit best. For a step-by-step walkthrough of repeated rows, taxes and totals, read how to extract invoice line items, taxes, and totals automatically.

FAQ

Invoice data extraction questions

What is invoice data extraction?+
