FAQPage Schema
How do I extract structured data from PDF and Excel files securely?

To extract structured data securely from PDF and Excel files, you need a sandboxed parsing tool that isolates file analysis. This method filters hidden instructions and malicious metadata, ensuring only sanitized, non-executable data is processed for safe extraction.

What is sandboxed document processing and when do I need it?

Sandboxed document processing isolates file parsing to prevent unauthorized command execution. You need it when analyzing external PDF, DOCX, or XLSX files to mitigate risks from hidden instructions or zero-width characters embedded in the documents.

How do I parse financial figures from multiple PDF invoices without executing hidden commands?

To parse financial figures from PDF invoices safely, use a security-first document parser that implements rigorous input sanitization. This strips out hidden malicious commands and zero-width characters, allowing you to extract structured data without triggering unauthorized scripts.

Does document-pro support text and table extraction from Word and PowerPoint files?

Yes, document-pro supports multi-format parsing for DOCX and PPTX files. It seamlessly extracts both text and tables from Word and PowerPoint documents alongside PDF and Excel formats, filtering malicious metadata during the extraction process.

Can I summarize a 50-page research report using automated document analysis?

Yes, you can summarize a 50-page research report by applying automated document analysis to extract key findings and summary points. The process parses the document text while automatically filtering hidden instructions to maintain data safety.

What are the limitations of automated PDF data extraction?

The limitations of automated PDF data extraction include potential risks from prompt injection if not processed in a secure sandbox. Without rigorous input sanitization and metadata filtering, hidden commands or zero-width characters in PDFs could execute unauthorized actions.
