# Converting Source PDF Files to LaTeX Files

Sometimes the only source material you have been provided to start creating the user guide are PDF files written in some other documentation tool or editor.

You could just ask for the original file but sometimes all you can have are PDF files. This was my conundrum.

The tools I used to convert the PDF file to a set of LaTeX files included the following:

• Adobe Acrobat, or some similar PDF reader that can export to Word or OpenOffice.
• OpenOffice to open the converted pdf files and save them as OO files.
• writer2latex installed in Open Office to convert the OO file to LaTeX files
• NotePad++ or a LaTeX editor to edit the resultant files

## PDF Source Material

The only source files I had were PDF files which were exported from a Confluence Content Management System. My task was to convert the pdf files to LaTeX.

Initially, I thought I could just copy out the text of the pdf file, but that quickly turned into a nightmare. So I ditched the Copy/Paste option.

Then I thought how about finding a way to export to a text file directly from PDF. Again, I’d be just left with one long text file and another massive headache. Not that option either.

I needed to find a way to generate text files of each section and subsection in the PDF file.

## Converting the PDF to LaTeX using writer2latex

After some research I found a software plugin that could generate a set of LaTeX files from Open Office. The solution I stumbled upon was to use a very helpful tool called writer2latex. This meant I needed to install OpenOffice (free) as well as a Java Runtime Environment (also free).

To use this tool I needed to be able to export the PDF file to a Word file or an Open Office file. Adobe Acrobat provides an export to Wordfunction.

Note: In the following procedures, I assume you are using Windows 10 and that you have OpenOffice and a Java Runtime Environment installed. If not, please install them before continuing.

writer2latex requires a Java Runtime Environment, version 6 or later. Ensure the JRE is installed first before doing the following:

2. In the dialog that appears, click Open with OpenOffice.org, then click OK.
3. In the OpenOffice Extension Manager, click OK to dismiss the Information dialog.
4. After the extension has been installed, click Close to dismiss the dialog.

### Create the LaTeX files Using writer2latex in OpenOffice

In the following procedure, you use writer2latex to output LaTeX files.

To create the LaTeX files

1. Open the PDF file in Adobe Acrobat Reader, or similar.
2. Select Export to Word (or a similar menu option)
3. Open the exported Word file in OpenOffice.
4. From the File menu in OpenOffice, select Export.
5. In the Export dialog, select LaTeX 2e from the Save as type dropdown, then click Save.
6. In the LaTeX Options dialog, accept the default settings or make changes as required, then click Export.
7. A set of LaTeX files (.tex files) will appear in the export directory.

### The Converted LaTeX File

The following is part of an example LaTeX output from the conversion process described above. Note the number of packages added by writer2latex.
