OmniDocMethods and steps for batch converting PDF to Excel
When processing multiple PDFs at one time, first determine whether the files are of the same template, and then decide whether to merge and export them one by one. This article gives complete steps for organizing files, merging pages, exporting to Excel and checking item by item.
Key points of this article
- When the file structures are the same (reports of the same template), they can be named uniformly, merged and then exported to save trouble in subsequent filtering and summarization.
- If the structures are different and each copy needs to be made into a separate table, organize the folders according to numbers, export them one by one and then summarize them to avoid mixing different tables together.
- The scanned PDF must be OCR recognized first, then exported, and the key figures must be checked against the original image.
- After exporting, check the number of rows, table headers, number formats, and source tags. If any problems are found, return to the original file to find the cause.
Many people have dozens of PDFs in their hands: monthly statements, sales reports for each branch, and data tables in the appendices of a batch of papers. Opening, copying, and pasting into Excel one by one is slow and easy to miss. If you are looking for a way to convert pdf to excel in batches, what you really need to solve are two things: first organize the files into a way that they can be processed together, and then decide whether to export them together after merging them, or export them one by one.
This article is written for office workers, students and researchers who need to convert multiple PDF tables into Excel. After reading, you can determine which files are suitable for merging and processing, and which files should be processed separately, and complete the export and verification step by step.
How to convert pdf to excel in batches? One sentence conclusion
One sentence conclusion: When the file structures are the same (such as reports of the same template), it is easier to export them after merging them; when each file is formed into a table, organize the folders, export them one by one, and then summarize them manually.
| your situation | Recommended practices | reason |
|---|---|---|
| Dozens of reports from the same template need to be summarized into one table | Name it uniformly, merge it into a PDF and export it to Excel | The table headers are consistent, and the merged data can be directly filtered and summarized. |
| Each PDF corresponds to an independent table and has no relationship with each other. | Organize folders by number, export one by one and save them separately | Merging will mix different tables together, making them difficult to separate later. |
| The document is a scanned copy or a mobile phone photo version | Do OCR to recognize the text first, then export it | The text in the scanned document cannot be selected directly, and it is easy to be misaligned or empty when exported directly. |
| There are only a few required tables in a long document | First split out the required pages and then export them | Reduce the interference of irrelevant pages and narrow the scope of verification |
| Large number of files and large differences in formats | First group them according to format, and use the same method to process each group | Only after the format is unified can the same set of standards be used for verification. |
Before you start: Confirm these points first
Taking ten minutes to judge before taking action can avoid rework.
- Whether the files are from the same template. The table header, number of columns, and field order must be consistent, so that the merged and exported data will match. Open two or three comparisons to see if the column names are the same.
- PDF is text version or scanned version. Use the mouse to try to select a piece of text in the file: the text version can be selected and copied; the text version cannot be selected and only images can be seen, usually the scanned version needs to be OCRed first.
- Does the table have merged cells or spread across pages? This type of table often requires manual adjustment after exporting. By looking at a few samples first, you can estimate how much time it will take to check later.
- What is the final result? Is it a summary table, or is there an Excel for each document. This answer determines whether to merge or process them one by one.
- Original files must be backed up first. Make a copy of the original folder and start again. After merging or splitting, you can return to the original at any time.
# steps to export PDF after merging multiple Excel in OmniDoc
The following steps apply to situations where the file structure is the same and need to be summarized into a single table. You can operate in the omnidoc.top or desktop client, and merge, split, and export are done in the PDF editor of the desktop client.
- install desktop client. download OmniDoc from download.omnidoc.top, which supports Windows, macOS and Linux.
- number the documents uniformly. * for example, it is named 01Jan. Pdf, 02 / Feb. pdf, and the number determines the order of the merged pages to avoid data disorder.
- Open the first file and add the rest. use the merge function in the PDF editor to add other files in numbering order and confirm the order one by one before merging.
- clean up the redundant pages. delete the cover, blank pages and duplicate header pages after merging; if the pages are in the wrong order, adjust them by reordering.
- process scanned pages. if there is a scanned piece, use the OCR function to identify the text first. The recognition result may be wrong, and the key numbers should be checked manually.
- Export to Excel. Select the export Excel format and save it to a separate folder with the file name indicating the data source and date, such as "2025 sales Summary _ merge Export .xlsx". Note that the date here is only a naming example, please fill in according to your actual situation.
- results of spot checks. Open the exported Excel, check the first line, the last line and the total line of each source, and make sure that the location of the segments is correct.
If each PDF is to be tabulated separately, repeat steps 3 through 6 for each file and export them one by one without merging. If you only need a few of these pages, split the pages in the editor before exporting.
# check item by item after completion
Export is not equal to completion, the following five suggestions are checked one by one.
| Check item | What do you think? | What if there's a problem? |
|---|---|---|
| Number of data rows | Compare with the number of lines of the original PDF, and check by source segments when merging files | The missing number of rows is mostly due to the truncation of the spread. Go back to the PDF editor to check the paging. |
| The header corresponds to the column | Is the heading of each column consistent with the original table? | When the column is misplaced, check whether there are merged cells and manually correct the header |
| Number and format | Spot check amount, date, percentage and decimal point | If the thousand quantile or decimal point is lost, the number is uniformly formatted and then checked. |
| OCR recognition result | Check several key figures against the original picture | The identification error needs to be modified manually. Please check the contents of the machine identification item by item. |
| Source mark | Can each line tell which document it came from? | If there is no source column, add a column by file name or page number in Excel |
# "Core comparison: merge export and export one by one
| Mode | An appropriate situation | Main points for attention |
|---|---|---|
| Unified export after merger | The same template should be summarized into a table | Must be uniformly numbered before merging, and source columns must be added after export. |
| Export and summarize one by one | Each document has its own table. | Files take a long time and take a long time, so it is necessary to prevent copy omissions when summarizing. |
| Online conversion website uploads one by one | Few files and no sensitive data | Pay attention to the size limit of the file, whether it is watermarked, and whether the file is saved |
# frequently asked questions (FAQ)
1. It is too slow to process dozens of documents one by one. What should we do?
Group by template or format first. The files of the same group are merged and exported uniformly, and different groups are processed separately. It is easier to find the problem by checking it once after each group is finished than after checking it all.
2. How to choose a free PDF to Excel tool?
There are four points to look at when selecting: file size limit, whether the export result is watermarked, whether the file will be uploaded and saved, table typesetting and whether the digital format is retained. Documents containing personal information or financial data are preferred to be processed locally.
3. What is the reason for the dislocation of the exported table?
There are three common reasons: the spread of the original table, the existence of merged cells, or the wrong OCR recognition of the scanned piece. First go back to the original document to check the pagination, then confirm the identification result, and finally manually correct the header.
4. What does the scanned version of PDF need to do first?
First use OCR to recognize text, and then export. The recognition results may be incorrect, especially the numbers, decimal points and dates, which should be checked item by item against the original picture.
# Summary
The key to the batch conversion of pdf to excel does not lie in the tools, but in the pre-arrangement: the files with the same template are merged and exported uniformly, and the files with different structures are processed one by one, and checked according to the list after export. Follow the steps in this article, and there will be much less repetitive work.
