My MS Office and Excel language is English. I am working with English documents most of the time, so I want to keep it that way. Temporarily changing the language options is also not an option.
When I am working with documents in other languages, this means that all the regional settings are overridden.
One example: In an English spreadsheet, the numbers are formatted as 1,234.56. In most non-English languages, the comma (,) is used as the decimal separator, so the number should e.g. look like this: 1.234,56.
If the spreadsheet is created by someone in a foreign language and I just want to open (maybe adjust) and print it, the format is broken.
How can I set the format of a single document in MS Excel (or Office)?
