I’ve got a bunch of invoice PDFs from a client that need to end up as structured data for an import script, and I’m on a tight deadline since they want it by tomorrow morning. Copying text by hand isn’t going to work with around 200 files, so I’m stuck on how to get the fields out in a usable format.

Honestly, with 200 files I’d skip manual anything and script it. Python with pdfplumber or PyPDF2 can pull the text out, then you just map the fields and dump to json with the built in json module. If the invoices all share one layout it’s pretty quick to set up. Scanned images instead of real text would be the only headache.

I had this exact headache with dental supplier invoices last month. What worked for me was uploading them to PDFcap ([pdfcap.com](http://pdfcap.com)) to convert the PDFs straight into JSON. It pulled out all the text fields into structured code in a couple of minutes, which saved my evening.

Had the same thing last month with sponsor invoices and it was a headache. For structured data like that you really need something that does OCR plus field recognition, straight copy paste won’t hold the layout together across 200 files. If the invoices follow a consistent template, even a basic script reading text positions might get you further than manual work tonight.

Dealing with invoices is a nightmare, which I learned the hard way doing my own market accounts. My tip is to run a basic Python script to pull the raw text into a dictionary if the layout is identical. Avoid trying to map exact page coordinates because a tiny shift will ruin your JSON. Just parse the standard text lines instead.

[SneakySteel](https://pdfbookslib.com/discussions/u/SneakySteel) good call on checking the text layer first, I’d test one invoice before running all 200. My old laptop chokes on big batches, so I work in chunks.

@Emily.7 Testing one first is smart, especially to see whether the PDFs have a usable text layer or need OCR. I’d also process them in small batches and validate a few JSON records before running all 200.

</div>

For invoices, I first check whether the PDFs have real text or are scans, because that changes everything. If the layout is consistent, OCR them if needed, then extract text and use a small script with field rules for invoice number, date, totals, and line items. I learned the hard way that a quick sample of 10 files catches layout exceptions before you run all 200.

That sounds doable. Check one sample for selectable text: digital PDFs are fastest with pdftotext -layout, while scanned ones need OCRmyPDF or Tesseract. Then parse the output into JSON with Python or an invoice extraction tool, and validate 10-20 files before the full batch. Share a redacted sample and target schema, and I can suggest the quickest pipeline.

@wallabies the `-layout` flag is the bit people miss. I ran pdftotext -layout over a batch of claim PDFs last week and the columns actually stayed readable, so mapping lines into JSON was straightforward. Test 10 first, then run the rest, one odd template will bite you otherwise.

</div>

first thing i’d check is if the text is selectable in the pdfs. if it is you can batch extract with python and pdfplumber then format as json, that’s what i do for tenant receipts. not sure if it’s the same on mac though. 200 files by morning is gonna be close

First check if the text is actually selectable or if these are scans, that changes everything. I did the same thing with expense reports last year using a small Python script with pdfplumber, looping over the folder and pulling fields like invoice number, date and total with regex. If they turn out to be scans you’ll need OCR first, honestly ocrmypdf handles that for free.
