Extract structured data from PDF not working correctly

I’m trying to read the table from the PDF file using the “Extract Structured Data” activity.

In some cases it works like a charm, but there are some cases when some letters are left out.

I inspected the PDF document using UiExplorer and it does leave out some letters in the column:

What can I do to avoid this? Maybe there are some other ways to read a table from this type of PDF document?

instead of extract complete table at once you can try screen scraping as well increment the page number and you can extract column by column
