I have a single cell with the value:
426,427,433,439,442
This isn't a number, rather a list of numbers. If I try to add another number to the list, for example, 679. Excel changes the cell to read:
679,426,427,433,439,000
If I select the cell and format it as "text", it changes to:
4.26427E+14
I've tried various cell formatting options, but I can't seem to get Excel to treat these numbers like text.
