Smart Fields Table Data

Version 12 Laserfiche AI

Updated December 23, 2025

asked on November 25, 2025 • Show version history

New to Smart Fields and testing various things. One interesting project is to pull line-item details from a table. In the tests I have run so far, the first line pretty much always returns correctly but the lower lines run into issues. Not OCR mis-read, but like data from one column being pulled into the field for a different column.

Has anybody run into this? Any ideas about a prompt or other change to do better on the lower lines? It's almost like ChatGPT runs out of steam after the first line and then doesn't work quite so hard.

We have made some enhancements to Smart Fields to improve dense table extraction for documents in similar formats that you have posted. I was able to get good results with the following table with the latest updates.

With the table extraction enhancements which are released, please see if you are able to get better results.

@Pieter - Just wanted to check-in if you did see better performance here after this change? Thanks!

Hi Pava-

This is currently at the level of a side project so haven't returned to it. Should have some time to do more over the next couple of weeks.

Hi again, Pava-

Update here. Still haven't done a super thorough analysis but this is what I'm seeing:

Yes, it's much improved
It seems like for this project, if we were to move forward, we would need a couple different templates based on general layout and then probably a handful that are vendor-specific.
1. And at its current state we would need manual QC rather than trusting full automation and using thresholds as a check.
I wish there was some feedback--at least coordinates on the page--for what the AI engine is returning. Fine-tuning feels like a guessing game.
I also wish that the AI prompt could be template-specific, so I could have the same set of fields but then just change the prompts
I had some surprisingly good luck with some MTRs that didn't even use the chemical symbol but had the word written out with the percentage next to it. Meaning, layout was not at all what the prompt set up but it still knew what I wanted
I had some issues with skewed pages throwing off the columns
The big crazy one attached earlier did quite well. One thing I noticed is that duplicated lines got consolidated to only show up once in metadata. Not sure if that's a good or bad thing or what changes might lead it to list the multiples

Can you send us a sample doc? It might have to do with the quality of text extracted from images with that background.

Thanks, Miruna-

I'll attach 2 sample docs. The Hydro one is the one from the screenshot. Note that after the screenshot above I made a new template and tailored my prompts specifically for this 1 vendor, as opposed to 1 template for various different vendors, and it did do better but still missed that middle Cr value.

For context, there is a separate large, expensive AI project underway to extract these chemical values--along with other things--and automatically upload the values into an ERP system. I'm hoping that we can do it with Laserfiche because it would be much faster and cheaper. But it has to be super accurate.

And yes, these images were scanned from paper, and I expect to need to be able to process that way. We do receive PDF copies ahead of shipments but they aren't always accurate. Like, the specific piece of metal might get changed for the shipment, which would mean the heat number and chemical analysis would be different.

EDIT: I keep getting a server error when trying to attach PDF files (73 and 262 KB). As did pasting a screenshot of the error message.
