Question details

The user needs to extract text from a CAD drawing saved as a PDF into an Excel spreadsheet, but standard extraction only produces a few scattered words.

How to Extract Text from a CAD PDF into Excel

Product: PDF Converter
Device & OS: not provided
Scenario: Converting architectural or engineering CAD drawings saved as PDFs into structured Excel data.
Observed behavior: Exporting or extracting text from the CAD PDF yields very few words, regardless of whether the PDF is flattened or contains layers.

Before you start

Check if the text in your CAD PDF is selectable by trying to highlight it with your cursor. If the text acts like an image or is made of vector paths, you will need to use Optical Character Recognition (OCR) to make it readable.

Solution 1Recommended

Use OCR to Recognize and Extract Text

If the CAD labels are vectorized or scanned as images, OCR can convert them into selectable text before you export the document to Excel.

CAD software often exports text as vector graphics rather than standard fonts. Running an OCR tool will scan the visual shapes of the text and convert them into machine-readable characters.

Open the PDF

Open your CAD PDF in a PDF editor equipped with OCR capabilities.

Run OCR

Navigate to the Tools or Edit menu and select the 'OCR' or 'Recognize Text' option. Apply it to the entire document.

Export to Excel

Once the text is recognized, choose the 'Export PDF' or 'To Excel' feature to convert the newly readable text into a spreadsheet format.

Clean up the data

Open the resulting Excel file and manually adjust the formatting, as complex CAD layouts often cause text to misalign in spreadsheet cells.

Manual Formatting Required: Due to the lack of structured tables in visual CAD drawings, the exported Excel file will likely require manual cleanup to organize the extracted labels correctly.

Solution 2

Use Native CAD Software for Data Extraction

Sometimes, the most accurate way to get text out of a CAD drawing is to use the original CAD program instead of relying on a PDF intermediary.

Powerful PDF to Excel Conversion

Extract PDF Text to Excel with WPS Office

WPS Office includes an advanced PDF toolkit featuring built-in OCR and seamless PDF to Excel conversion, making it easier to digitize your CAD drawings accurately.

1. Open the CAD PDF: Launch WPS Office and open your CAD PDF document.
2. Apply OCR: Go to the 'Tools' tab and select 'OCR' to recognize any non-selectable text in the drawing.
3. Convert to Excel: Still in the 'Tools' tab, click 'PDF to Excel' and follow the prompts to save the file as an .xlsx document.

Frequently Asked Questions

Why can't I select the text in my CAD PDF?

When CAD software exports drawings to PDF, it often converts text into vector paths (lines and curves) to preserve the exact visual appearance. Because it is no longer recognized as font characters, standard PDF tools cannot highlight or extract it.

Can OCR perfectly recreate my CAD tables in Excel?

OCR is excellent at recognizing words, but visual CAD drawings lack standard table metadata. The resulting Excel file will have the text, but you will likely need to move the cells around manually to recreate the specific layout of your CAD schedules or labels.

Are there specialized tools for CAD to Excel extraction?

Yes, there are specialized data extraction services and advanced engineering software designed specifically to parse CAD PDFs into structured Excel formats. However, for everyday users, utilizing OCR in a capable PDF editor is the most accessible solution.
