If you try to highlight the text and nothing happens, you're probably dealing with a scanned PDF. That makes traditional copy/paste almost useless.
Step 1: Identify whether your PDF is scanned
Try selecting some text.
If you can't select individual words or characters, the PDF may consist of scanned images rather than actual text.
Common examples include:
- scanned textbooks
- old reports
- photographed documents
- scanned worksheets
- historical documents
- scanned research papers
- documents printed and scanned back into PDF
Step 2: Open Tablio's scanned-document extraction workflow
Open the appropriate Tablio extraction tool and upload your scanned PDF.
Step 3: Let Tablio process the document
Scanned documents require more than ordinary text extraction.
The system has to interpret the page visually and identify the information that forms the table. This is particularly useful when you need structured data from a document that was never created as a digital spreadsheet.
Step 4: Check the extracted table carefully
OCR and document recognition aren't magic. Pay particular attention to:
- decimal points
- commas
- dates
- numbers
- symbols
- column boundaries
- handwritten content
- low-resolution scans
For important academic, financial, or professional data, always verify the extracted result against the original document.
Step 5: Export the result
Once you're satisfied with the extracted data, export it using the available Tablio format.
You can then edit, filter, sort, calculate, and analyze the information normally.
Why scanned PDFs are difficult
A normal digital PDF may contain actual text such as:
Revenue: €52,430
A scanned PDF may instead contain nothing more than an image of those characters.
Your computer sees a picture. You see a number. Extracting the number requires document recognition.
That's why simply copying and pasting a scanned table doesn't work.
