How to Extract Key Information from a PDF with AI
PDFs hide their structure. Copilot can pull out the specific facts you need — dates, requirements, totals — without making you read the whole thing.
What it is
PDFs are the format you receive when someone wants to send you something fixed and final — contracts, invoices, regulatory documents, formal proposals, scanned forms. They’re great for distribution but terrible for reading on a screen and worse for finding specific information. Copilot can read PDFs natively (when they’re in your SharePoint or OneDrive), and it can extract specific data points without you having to scroll through 40 pages.
The skill is in framing the request. Don’t ask ‘what’s in this PDF?’ — that produces generic summaries. Ask for the specific things you need: ‘extract all dates and what each one represents’, ‘list every requirement marked as mandatory’, ‘find the total cost and break down what it includes’. The more precise the question, the more useful the answer.
For scanned PDFs (image-based, not text-based), results vary. Copilot needs to read text from the image, which works for clean scans but struggles with poor-quality ones. If results look wrong on a scanned PDF, it might be the OCR quality rather than Copilot getting confused. The fix is usually to ask for verification or run it through a better OCR tool first.
When to use this
- When you’ve been sent a long PDF (contract, policy, report, proposal) and only need specific details.
- When you need to extract structured data — dates, costs, requirements, parties.
- When you need to compare PDF content against a checklist.
- When you want a table of key fields rather than reading the whole document.
How to do it
- Open the PDF in its source location (SharePoint/OneDrive, not a download).
- Open Copilot Chat or Copilot in your file viewer.
- Ask for the specific fields you need, with page references where helpful.
- Request structured output (table, bullet list) — easier to scan than prose.
- Refine if results are too broad or too narrow.
- Verify critical extractions against the source — especially page numbers.
- Copy useful output into a checklist or notes for action.
Best practices
- Be specific about what you want extracted. Fields, headings, timeframes — name them.
- Ask for page numbers or section titles. Lets you verify quickly.
- Request a table for structured results. Far easier to scan than paragraphs.
- Always verify against the source for legal or compliance content. Treat output as a draft summary.
Common mistakes
- Asking ‘tell me about this PDF’. You get a vague summary. Be specific.
- Trusting extractions on scanned PDFs without checking. OCR quality affects accuracy.
- Skipping page reference requests. Without them, verifying takes much longer.

How do I extract specific information from a PDF with Copilot?
Open the PDF in Copilot Chat (drag it in, or reference a SharePoint URL). Ask a specific question: ‘Extract all dates and amounts mentioned in this contract.’ Specific questions get specific answers; vague prompts get vague answers.
Can Copilot read scanned PDFs?
Modern Copilot handles many scanned PDFs via OCR, but accuracy drops sharply with poor scan quality, handwritten content, or unusual fonts. For mission-critical extraction from scans, verify Copilot’s output against the original — don’t trust silently.
How do I extract structured data from a PDF into a table?
Ask Copilot to ‘extract this as a table with columns for [name, date, amount]’. Copilot returns a Markdown table you can paste into Word or Excel. For repeat extraction across many PDFs, use Power Automate’s AI Builder document understanding — better for scale than ad-hoc Copilot prompts.
Why does Copilot get numbers wrong when reading PDFs?
OCR errors, PDF column ordering issues, and AI hallucination on numeric data are all common failure modes. For any extracted number that matters financially or legally, verify against the source document. Treat Copilot as a fast-first-pass tool, not the final answer for numerical accuracy.
