mso-dumper now packaged in OBS

Share Button

I’m happy to announce that the mso-dumper tool is now packaged in the openSUSE build service under my home repository. This tool is written in Python, and allows you to dump the contents of MS Office documents stored in the BIFF-structured binary file format in a more human readable fashion. It is an indispensable tool when dealing with importing from and/or exporting to the Office documents. Right now, only Excel and Power Point formats are supported.

This package provides two new commands xls-dump and ppt-dump. If you wish to dump the content of an Excel document, all you have to do is

xls-dump ./path/to/mydoc.xls

and it dumps its content to standard output. What the output looks like depends on what’s stored with the document, but it will look something like this:

...

I have originally written this tool to deal with the Excel import and export part of Calc’s development, and continue to develop it further. Thorsten Behrens has later joined forces and added support for the Power Point format. Right now, I’m working on adding an XML output format option to make it easier to compare outputs, which is important for regression testing.

    1. Yes, it should just run fine on Windows also. We don’t use any platform specific API in the code.
