Can you go into detail on how this specific cell  is to be formatted? The
example you gave indicated

[>=10000000]#\,##\,##\,##0;

[>=100000]##\,##\,##0;

##,##0
As far as I can see the format  for 100 thousand to 10 million is the same as
the format for under 100 thousand. You can use a single format and rather
than a condition based format you can use the Positive;Negative;Zero;Text
