Question details
The user experiences formatting issues where the content becomes stretched or produces incorrect data after converting a PDF into an Excel spreadsheet.

- Product
- PDF Converter
- Device & OS
- not provided
- Scenario
- Converting a PDF document containing data or tables into an editable Excel spreadsheet to analyze the extracted information.
- Observed behavior
- The resulting Excel spreadsheet displays stretched cells, distorted formatting, and incorrect data extraction instead of accurately matching the original PDF layout.
Determine if your PDF contains selectable text or is a scanned image, as this dictates whether you should turn on Optical Character Recognition (OCR) during conversion.
Disable OCR for PDFs with Selectable Text
Turn off OCR during conversion if your PDF already contains native, selectable text, as the OCR engine may attempt to recreate the layout unnecessarily and cause stretched cells.
When converting a standard digital PDF to Excel, applying OCR can sometimes confuse the software. It attempts to visually map out text using complex spacing and merged cells, leading to stretched data. Disabling this feature allows the converter to pull the embedded text directly.
Launch your PDF to Excel converter and navigate to the preferences or conversion settings menu.
Find the setting labeled 'Optical Character Recognition (OCR)' or 'Recognize Text'.
Uncheck the box or toggle the setting to disable OCR for the current file.
Start the PDF to Excel conversion process again and open the newly created spreadsheet to verify that the stretched layout is resolved.

Enable OCR and Manually Adjust Scanned PDFs
If your source PDF is scanned or image-based, OCR is mandatory to extract the text, but you may need to manually clean up the resulting Excel columns.

Frequently Asked Questions
Why does my converted Excel file look stretched or misaligned?
This happens when conversion software tries to replicate the exact visual layout of the PDF by adjusting column widths, row heights, or merging cells. Disabling OCR for text-based PDFs or using an intelligent converter like WPS Office usually prevents this.
How do I know if my PDF requires OCR before converting?
Try selecting the text in the PDF with your mouse. If you can highlight individual words and copy them, the PDF is text-based and does not need OCR. If your cursor highlights the entire page as a single image, it is a scanned document and OCR is necessary.
Can I fix the stretched cells directly in Excel after conversion?
Yes. You can select the entire worksheet in Excel, navigate to the Home tab, click on Format, and choose 'AutoFit Column Width' and 'AutoFit Row Height'. Additionally, highlighting the data and clicking 'Unmerge Cells' often helps fix distorted structures.
Does WPS Office support converting scanned PDFs into editable Excel spreadsheets?
Yes, WPS Office includes advanced OCR technology that can extract text and table data from scanned PDF files and convert them into fully editable Excel spreadsheets with high structural accuracy.
