Tilman Hausherr commented on PDFBOX-4293:
-----------------------------------------

Yes that's the way it is… we don't fill blanks. You should use ExtractTextByArea if you
know the coordinates, or use a product like Tabula.

>  I have to convert Pdf's to database data. I developed a parser that reads .txt files.
The original data is available in PDFs only . Therefore .txt files will have to be created
by Tika converting the PDF's to .txt. After conversion I recognise an alignment issue with
the .txt data compared to the  columns in the PDF. On the TIKA website I read that I need
to check if the problems also occurs in PDFBox, so I checked for that. PDFBox has the same
issue.
> These lines of PDF data:
> a  b  c  d  e   
> a  b  c  d      e
> are both presented as
> a  b  c  d  e
> in the text file, causing for example numbers to be presented in the wrong "column".
> Unfortunately I cannot share busniess documents, but i have created an example in Excel,
saved it as PDF and converted it to .txt. See attachments.
> In addition I converted the testset online with Convertio.co. Their results is as expected,
with enough spaces between the words/numbers to recognise the column.
