  Extract PDF extracts structured data from PDFs and images, including tables, OCR text, images, and stamps, built on ComPDF data extraction and AI document extraction capabilities with exports to JSON, XML, CSV, Excel, TXT, or HTML for automation, analytics, and LLM workflows. It suits triggers such as “extract pdf text,” “extract tables from pdf,” “pdf ocr,” “pdf to json,” “parse invoice pdf,” and “extract data from pdf.” Example queries include “Extract all tables from this PDF and export them to CSV,” “Parse this invoice PDF and return the amount, vendor, and tax ID,” and “OCR this scanned PDF and return structured JSON.”

# PDF Extract

Process PDF files through ComPDF Cloud REST API. Supports 50+ document processing operations.

Official documentation: <https://www.compdf.com/guides/api-reference/v2/overview?utm_source=clawhub&utm_medium=skillhub&utm_campaign=pdf_skill_pdf_extract&ref_platform_id=clawhub_skills>

## When to Run

- User requests to convert file format (e.g., "convert this PDF to Word", "convert Excel to PDF")
- User requests to edit PDF pages (e.g., "merge these two PDFs", "delete page 3", "rotate PDF")
- User requests to add or remove watermarks from PDF
- User requests to compress PDF files
- User requests OCR recognition of scanned documents or text in images
- User requests AI extraction or parsing of document content
- User requests to extract tables from images
- User requests batch processing of multiple document files
- User requests to compare differences between two PDF documents
- User mentions ComPDF, compdf, or related keywords

## Workflow

### Step 1 — Obtain API Key

Check whether `config/public_key.txt` exists and contains a non-empty value.

- **If the file exists and is non-empty**: use the stored key (trim whitespace).
- **If the file is missing or empty**: ask the user for their ComPDF API Public Key. Inform them it can be obtained at <https://www.compdf.com/compdf-portal/signin?utm_source=clawhub&utm_medium=skillhub&utm_campaign=pdf_skill_pdf_extract&ref_platform_id=clawhub_skills>. After the user provides the key, ask whether they would like to save it locally for future sessions.
  - If the user agrees, write the key to `config/public_key.txt`.
  - If the user declines, use the key for the current session only without saving.

> The key file is **not included in the published skill package**. It is created at runtime only when the user explicitly opts in. The user may delete `config/public_key.txt` at any time to revoke local storage.

### Step 2 — Confirm External Upload Intent

**Before uploading any file**, explicitly inform the user:

> ⚠️ **External Upload Confirmation Required**
>
> Your file will be uploaded to ComPDF's servers (api-server.compdf.com or api-server.compdf.cn) for processing. Please confirm that:
> 1. You consent to uploading this file to external servers.
> 2. The file does not contain highly sensitive or confidential data, or you
