PDF document content extraction: how to export text and tables

Key points of this article

First determine whether the PDF is a digital version or a scanned version. The extraction paths of the two are different. If you make a wrong judgment, your work will be in vain.
The digital version of PDF can directly export text and tables; the scanned version must be OCR recognized first and then exported.
Text is suitable for exporting to Word, tables are suitable for exporting to Excel, and presentation content can be exported to PowerPoint.
After exporting, you need to check the numbers, headers, merged cells and paragraph order page by page. It cannot be used directly as a final draft.

What many people need is not the entire PDF, but several paragraphs of text or tables within it: the data in a report needs to be put into tables to continue calculations, the reference table of a paper needs to be moved into courseware, and the terms of a contract need to be compiled into documents. Direct copying and pasting will often result in confusing line breaks and broken sentences, and the table will become a long string of text without column boundaries. What PDF document content extraction needs to solve is to cleanly extract the content and retain a structure that can continue to be used.

This article is written for people who need to extract text and tables from PDFs, such as students who organize literature, staff who check data, and operations staff who need to reuse report content. After reading, you will know how to determine the type of PDF first, how to export text to Word and tables to Excel in the OmniDoc desktop client, and what areas to check after exporting. The method in this article is also applicable to other tools, but the specific interface will be different.

How to extract text and tables from PDF? One sentence conclusion

The digital PDF can be exported directly, while the scanned PDF must first recognize the text. Text is suitable for exporting to Word, and tables are suitable for exporting to Excel. The table below provides recommended practices for common situations.

your situation	Recommended practices	reason
A digital PDF with text that can be selected, and the content is mainly paragraphs	Export directly to Word and organize paragraphs in the document	The text layer already exists, and the export can preserve the paragraph and title structure.
PDFs with text that can be selected, mainly data tables	Export to Excel, check column alignment table by table	Tables are exported as cells for easy sorting, calculation and checking
Text cannot be selected in PDFs generated from scans or photos taken with a mobile phone.	First use OCR to identify, and then export it as a digital version.	Scans only have images, no text layer to extract
Need to put content into slides	Export to PowerPoint and adjust by page	The exported results are organized by page to facilitate further typesetting.
Just a few words	Directly select and copy, then check the line break after pasting.	When the quantity is small, the operating cost is lower than the entire export

Before you start: Confirm these points first

First determine whether it is a scanned copy. Open the PDF and try to select a piece of text with your mouse. If it can be selected and highlighted, it means it is a digital version and the text already exists in the file; if only the entire page of the image can be selected, or cannot be selected at all, it is probably a scan and needs to be OCRed first. Misjudgment will result in an empty export or a bunch of garbled characters, so this step cannot be omitted.

Confirm whether you want text or a table. Text export cares about paragraphs, titles and order; table export cares about rows, columns and cell boundaries. When the two are placed on the same page, they can be exported separately to avoid the columns of the table being split into rows of ordinary text.

Confirm end use. If the results need to be edited, Word is the appropriate intermediate format; if calculations or statistics are to be done, Excel should be entered directly; if reports are to be made, PowerPoint should be considered. The export format will be different depending on the target. If you choose the wrong one, you will have to convert it again later.

Be aware of the layout complexity of the PDF. Multi-column layout, headers and footers, footnotes and cross-page tables will all cause the order of the exported results to change. When the number of pages is large, it is recommended to export one or two pages to try and confirm that there are no problems with the structure before processing the full text. For example, for a 30-page paper, you can first test on pages 5 to 7.

Prepare a save location. The export result will usually be a new file. It is recommended to create a separate folder for each PDF and put the original file, exported Word and Excel together for easy reference.

Steps to export text and tables in OmniDoc desktop client

The following steps use the OmniDoc desktop client as an example. The client supports Windows, macOS, and Linux, and the PDF editor includes functions such as OCR recognition, export to Word, Excel, and PowerPoint.

Open the desktop client and load the PDF. Open the file to be processed in the client and confirm that the page displays normally and there are no missing pages.
Check the text layer. Try to select a text. If it can be selected, it will enter the digital version process; if it cannot be selected, it will enter the next step of the OCR process.
Perform OCR on the scan. Perform text recognition on the scanned page in the PDF editor. After the recognition is completed, try to select the text again to confirm that the text can be selected.
Determine the export scope. If you only need part of the page, first extract or select the corresponding page in the page operation to avoid exporting the entire page and then deleting irrelevant content.
Export text to Word. If you choose to export to Word, the resulting document will retain the paragraphs and rough heading hierarchy, and you can continue to organize it in Word.
Export the table to Excel. Select Export to Excel and check table by table whether the rows and columns are consistent with the original text, paying special attention to the table header with merged cells.
Export to PowerPoint if needed. If the content is to be used for reporting, export it to PowerPoint and check whether the content is complete by page before proceeding with subsequent typesetting.
Save and check item by item. Save the export file to a separate folder and check each item using the checklist below.

Check each item after completion

Export completion does not mean the content is available. Deviations may occur in machine recognition and format conversion, especially numbers, symbols and table structures, which need to be checked item by item against the original PDF. For the content recognized by OCR, important numbers and proper nouns should be particularly checked, because machine recognition will inevitably have errors.

Check items	How to see	What should you do if there's a problem?
Numbers and units	Extract several key numbers and compare them with the original PDF with decimal points, millenths, and units	Re-check the original page, and if necessary, perform OCR on that page before exporting
Meter header and row	Check the number of columns, rows, and header positions against the original table	Manually adjust the cells; merged cells can be split and re-filled
Paragraph order	Read it from start to finish and check if the multi-column content is scrambled	Paragraphs are rearranged in the original order, and if necessary, export by column or page
Header, footer, and page number	Check if repeated headers and footers from each page are mixed in	Remove duplicate content in Word or Excel to avoid counting it in future statistics
Special symbols and formulas	Check whether the superscript, subscript, Greek letters, and formulas are restored	If the formula is more complex, keep the original PDF page as a reference or use the corresponding formatting tool to re-edit it
Document integrity	Check whether the number of pages, chapters, and tables matches the original document	Missing pages are exported separately to fill in and then merged into the final file

📊 Core Comparison

There are four common methods for extracting PDF content, each suitable for different scenarios. The table below compares them from three aspects: suitable scenarios, advantages, and considerations.

Method	Suitable for the scene	Advantages	Notes
Copy and paste directly	A few sentences or a short passage	Easy to operate with no additional steps required	Tables are prone to misalignment, and paragraph breaks require manual editing
Export to Word	This is a long piece that needs further editing	Preserve paragraph and title structure for easier editing	After exporting the spreadsheet, it may need to be reorganized
Export to Excel	Data tables that need to be calculated or filtered	The row and column structure is clear, making it easy to count and verify	Pure text paragraphs are usually not suitable for reading after exporting
Use online conversion websites	Temporary conversion of confidential content does not involve it	Simply upload and convert—simple operation	Pay attention to file size limits, whether to add watermarks, privacy handling after uploading, and whether formatting and tables are retained

When confidential content is involved, local processing methods should be prioritized, and it should not be casually uploaded to third-party websites.

❓ Frequently Asked Questions (FAQ)

1. Can the text from a scanned PDF be exported directly?

Usually, it cannot be exported directly because the scanned file contains only images and no optional text layers. You need to perform OCR recognition first to make the text selectable and exportable content, then proceed with subsequent operations. Recognition results should be checked against the original text, especially the numbers.

2. What should I do if the exported table columns are misaligned?

First, confirm whether the original PDF table has wireframes and fixed column widths. Tables without wireframes are easily split or merged during export. You can manually adjust column widths in Excel, or correct misaligned cells one by one to confirm the data ownership of each row against the original table.

3. How should I choose a free PDF extraction tool?

First, look at several aspects: whether there are file size restrictions, whether the export results will have watermarks, whether the files are processed locally, and whether the layout and tables can be retained. During the trial, you can test with a PDF containing tables and multiple columns to check whether the results are usable, rather than just looking at the interface to be simple.

4. Can the extracted content be directly quoted or published?

It is not recommended to use them directly. Whether in OCR recognition or format conversion, errors may occur; verify data against the original text before quoting it. Content involving formal reports or public releases requires manual review.

5. Can the text in the images be extracted?

Yes, as long as the image is part of the PDF and has sufficient clarity, it can be recognized through OCR. The blurrier, more tilted, or uneven the lighting of the image, the worse the recognition performance. It is recommended to process the original image clearly before performing recognition.

📝 Summary

When extracting text and tables from PDFs, the key is to first determine the file type, then choose the appropriate export format, and finally check the results item by item. Digital PDFs can be exported directly, but scans must be done with OCR first; Text is best suited for Word, tables for Excel. Following this process results in PDF document content extraction will be more stable and easier to continue using.
