Please do not use Excel, prefer R or python instead.
ok thanks for your help
Could be a number of things. Its almost certainly not biologically meaningful, so is most probably Excel doing something like failing to display a very large or very small decimal value correctly. Follow Ram's suggestion and look at the data outside of Excel to be sure.
