I have doc with 20 sections with some section prefix.
How to export this section into 20 individual pdfs, if possible, with section prefix as name of new pdf?
I'm pretty sure that would require a script. You can now separate into individual pages in the File > Export > PDF (Print) dialog but not as you specify. You might ask in InDesign Scripting:
Have you found an answer?
Try this free script. I think it has what you need, at least close to it. Sections will be numbers, not actual section names (so they sort correctly). Let me know if it works. If not, I could tweak for actual section names, if it is a must.
you could iterate over all sections in your document and calculate the pageRange for the PDF export.
here is the key code snippet:
var curPageNameWithPrefix = getPageNameWithPrefix(curPage);
app.pdfExportPreferences.pageRange = curPageNameWithPrefix;
app.activeDocument.exportFile(ExportFormat.PDF_TYPE, curPDFfile, false, curPDFJobOptions);
You may also need the property documentOffset:
firstPageIndex = curSection.pageStart.documentOffset;
This is a pretty old thread but I had the same question in 2022. My solution: select all the pages/spreads in the section you wish to export. (Pages can be out of sequence too if you use the CMD key to select.) Then right click and select > Print Spreads. In the resulting dialog box, set the Printer as "Postscript File" and then click Save. This will create a postscript file that you can open in Acrobat or Preview and then save again as a PDF. It sounds more complicated than it is. Seems the best option until Adobe decides to fix this odd bug.

Select them in the page panel, right mouse click and in the context menu you can export selected spreads.
You can download the pdf_individuals.txt file attached below and change the txt extention to jsx (pdf_individuals.jsx), then copy to your Indesign script panel folder to install. This script was originally downloaded from https://creativepro.com/files/kahrel/indesign/pdf_individuals.html
You can export sections named by the prefix, marker, etc.
Thank you for mentioning the script. But please include a link to the script rather than posting the script itself. Scripts are updated from time to time. Posted scripts are frozen.
