in current versions following behavior is implemented:
If BP language matches Windows language setting then Windows region settings are used.
If BP language does not match Windows language then BP region settings are used.
Example 1:
Windows language: English (US)
Windows region: German
BP language: English (US)
... BP uses German region settings
Example 2:
Windows language German
Windows region: German
BP language: English (US)
... BP uses English region settings
In example 2, data would be presented differently in eg Excel and in Blue Prism.
This behavior is not limited to German but affects all situations where Windows language and BP language does not match. However, also the opposite is true, eg when Windows and BP are both set to German then Windows region is used.
The idea is to have constant behavior regardless of language and if languages matches or don't match.
Please always consider Windows Region as the ruling formatting
