Description

📝 Description

This workflow automates the process of extracting text from receipt or document images using OCR.space and presenting the results in a clean, styled form.

It’s especially useful for cases like receipt digitization, invoice parsing, table recognition, or quick OCR text extraction directly inside n8n without third-party dashboards.

The workflow is lightweight and self-contained - all you need is an OCR.space API key.

🔄 How it works

Form Trigger – Upload File
A simple form collects the image (max 1 MB) and asks whether the file contains a table.
Normalize Inputs
Converts the “Yes/No” response into a boolean flag isTable and keeps the uploaded file attached.
OCR.space API Call
Sends the uploaded image to the OCR.space API with the correct parameters:
- language=pol (Polish by default, can be changed)
- OCREngine=2
- isTable flag
Display Results
The parsed text (ParsedResults[0].ParsedText) is rendered in a styled card with monospace formatting for easier reading and copy-paste.

🎯 Use cases

Receipt OCR for expense tracking
Invoice or document text digitization
Table parsing from scanned files
Quick OCR text preview in n8n flows

⚙️ Requirements

OCR.space API key (Header Authentication)
n8n instance running ≥ v1.20

📌 Notes & Customization

Language: change language parameter (eng, deu, etc.) to match your input.
Validation: add a file size check if you expect larger files.
Error handling: add an Error Trigger if you anticipate API rate limits.
Table vs Text: enabling isTable improves structured data parsing.
