The guys of ClearPeaks gave an interesting insight to the Xcelsius file format XLF. As they describe on their ClearPeaks Blog the XLF format is just a container, which can be extracted by renaming to zip extension.
The XLF-container contains:
- all images
- the excel model
- an xml file with the xcelsius specific definitions
This gives developers the opportunity to (batch) edit xcelsius projects without using the xcelsius designer application. So, where are the guys, who would like to code some alternative xcelsius editors. Hands up.
