Data Extraciton from PDF tables

[Rajesh_N]

Pls elaborate the best way to extract data from row in PDFs. Here issue is multiple PDFs generates by system and number of rows in each PDF are not constant, but COLUMNs remain same. ROWs count changing in each PDF. BOT has to extract rows data and post the data in excel file.
Appreciate any of your support here…

we used string manipulation and Document understanding already…

@Rajesh_N

You can try using regex if all the columns have data always…

If all columns does not have data essentially then you can try to check by reading the pdf with preserving format…and then count the characters for each column …so by understanding that…we can use fixed length approach to identify the data separately for each column even if some columns are not having data

It’s table ROWs issue and all ROWs carrying data. number of rows are not fix in PDF so if we use max limit in ROWS, BOT is extracting below lines (I mean BOX below data too)

@Rajesh_N

If you are using string manipulation…

Then if there is any speicific text to identify the end of table …then we can first split on that to get only the table data

If there is a specific pattern we can use regex to identify pttern for end of table

PDF Table extraction

Hi All, The above approach fails in some of PDF files. Can I use document understanding for pulling the data from multiple pdf pages i.e. banking statement? Table page is not fixed? Is it possible with DU?? or go with ABBYY Flexi capture?? Need expert advice here. See the example in my this thread. Regards Anand

Hi @Rajesh_N ,

Is it possible for you to share a sample PDF file having the same pattern that is present in the PDF inputs that you get from the system ?(not your confidential PDF).

Also, Do take a look at the post below for Table Extraction from PDF :

Converting Pdf table to excel

@Amit_Kumar_Charde , In that case, we should be able to read the PDF data using PDF Activities and apply String/Regex manipulation to get the data into a Datatable format. Is it possible for you to provide us with the PDF document or a Sample of that PDF having the same pattern of data as the original PDF document ? We could check if a String/Regex manipulation would be an easier approach for the pattern of PDF data that you receive. Additionally, Could you Check with the below workflow : P…

NDA in place to share PDF but let me try and revert
