How to Automatically Combine PDF Files Using Excel Data
Question details
The user wants to automate the process of merging multiple PDF files based on instructions and file tags specified in an Excel spreadsheet.
- Product
- PDF / Excel
- Device & OS
- not provided
- Scenario
- Creating automated workflows to merge base PDFs with other tagged PDF files in a specific order using Excel as a database.
- Observed behavior
- Needs to generate organized, print-ready PDF documents corresponding to data rows and specific file sequences listed in an Excel sheet.
Ensure all your base PDF files and tagged PDF files are saved in an accessible local folder, and that your Excel sheet contains the exact, accurate file names and paths.
Create a PDF Automation Script Using Python
Use a simple Python script with Pandas and PyPDF2 libraries to read your Excel sheet and automatically merge the PDFs in bulk.
Python is highly effective for automating file combinations. By using the Pandas library to read Excel rows and PyPDF2 to handle PDF operations, you can easily generate print-ready documents in the exact order specified by your tags.
Open your command prompt or terminal and run 'pip install pandas pypdf2 openpyxl' to install the required Python packages for reading Excel and merging PDFs.
Open your spreadsheet and ensure you have clear column headers for 'Base_PDF' and 'Tagged_PDFs' containing the exact file paths or file names.
Import pandas as pd and use pd.read_excel() to load your file. Create a 'for' loop to iterate through each row of the dataset.
Within the loop, initialize a PdfMerger() object. Use merger.append() to add the base file and the subsequent tagged files specified in that row.
Save the final document using merger.write('output_filename.pdf') and run the script to generate your combined files.

Easily Manage and Merge PDFs with WPS Office
While scripting is great for bulk automation, WPS Office provides a powerful, user-friendly interface to quickly merge, split, and edit PDF files manually, alongside full Excel-compatible spreadsheets.
- 1. Open PDF Tools: Launch WPS Office and click on the 'PDF' tab on the main interface to access the PDF toolkit.
- 2. Select Merge PDF: Click on the 'Merge PDF' option from the list of available tools.
- 3. Add your files: Click 'Add Files' and select the base PDF and tagged PDF files you wish to combine.
- 4. Arrange the order: Drag and drop the imported files in the preview window to match the exact sequence you need for printing.
- 5. Merge and save: Click the 'Merge' button to instantly generate your combined PDF document and save it to your desired folder.
Frequently Asked Questions
Can I combine PDFs using Excel macros (VBA)?
Yes, but VBA cannot manipulate PDFs natively. You will need to use VBA in conjunction with a third-party command-line tool (like PDFtk) or API to trigger the merging of the files.
Why are my merged PDF files losing their original formatting?
Formatting loss usually occurs if the merging tool flattens forms or drops annotations. Ensure your automated script or merging software is configured to retain interactive elements and original document metadata.
How do I ensure the files merge in the correct print order?
Your Excel sheet or tag list must dictate the exact sequence. When scripting, append the files to the PDF merger object sequentially exactly as they are read from left to right or top to bottom in your Excel data.
