Converting a PDF file to a nice table

Question

I have this PDF file which is arranged in 5 columns.

I have looked and looked through Stack Overflow (and Googled crazily) and tried all the solutions (including the last resort of trying Adobe Acrobat itself).

However, for some reason I cannot get those 5 columns in csv/xls format - as I need them arranged. Usually when I export them, the format is horrible and all the entries are arranged line by line with some data loss.

Here is a link to an excerpt of the file above, but I am really getting frustrated and am running out of options.

Answer 1

iText (or iTextSharp) could do this, if you can give it the boundaries of those 5 columns, and are willing to deal with some overhead (namely reparsing the page's text for each column)

Rectangle2D columnBoxArray[] = buildColumnBoxes();
ArrayList<String> columnTexts = new ArrayList<String>(columnBoxArray.length);
For (Rectangle2D columnBBox : columnBoxArray) {

  FilteredTextRenderListener textInRectStrategy = 
    new FilteredTextRenderListener(new LocationTextExtractionStrategy(), 
      new RegionTextRenderFilter( columnBBox ) );

  columnTexts.add(PdfTextExtractor.extractText( reader, pageNum, textInRectStrategy));
}

Each line of text should be separated by \n, so it becomes a simple matter of string parsing.

If you wanted to not reparse the whole page for each column, you could probably come up with a custom implementation of FilteredTextRenderListener that would take multiple listener/filter pairs. You could then parse the whole thing once rather than once for each column.
