Libreoffice Macro To Export Batch PDF

Here is the complete LibreOffice Basic macro code, incorporating all the requested features:

1. Exports as PDF.

2. Exports only the defined Print Area (A1:I37).

3. Uses the sheet "Report card t-1".

4. Names the PDF file based on the value in cell B7.

5. Loops through roll numbers 1 to 40.

You need to copy and paste this entire code block into your LibreOffice Basic IDE module.

Important Steps Before Running

1. Update Configuration: Double-check the four Const values at the top of the macro match your file's setup.

2. Define RollNoCell: Ensure the roll number input cell is named RollNoCell in the Name Box.

3. Create Folder: Manually create the folder specified in sOutputFolder (e.g., C:\StudentReports\).

4. Run: Go to Tools $\to$ Macros $\to$ Run Macro (or use the green triangle button in the IDE).

    

   2. Use a loop to extract page 128 from each PDF

   Linux/macOS (Bash):

   mkdir extracted_pages
   
   for f in /home/user/pdfs/*.pdf; do
       filename=$(basename "$f" .pdf)
       pdftk "$f" cat 128 output "extracted_pages/${filename}_p128.pdf"
   done
   
    
    

   This will create a folder extracted_pages with files like file1_p128.pdf, file2_p128.pdf, etc.
