  1. Thank you; this was useful when looking at my cell phone bill in more depth. Otherwise it just didn’t process the times correctly.

  2. Your suggestion has helped me tremendously. I bought laptop from Dubai. The number format was giving comma separator after every 2 digits. Now I have been able to change it to USA format. Many Thanks

  3. Works fine, but if I sent the file to somebody else who has other settings, it changes again. How can I put a format in in such a way it is not changed based on the region of any user when shared?

  4. Thank you so much. Ever since I got my new laptop some existing excel spreadsheets showed commas and point separators and the formulas did not work with a mix of both. This solved my problem.
