If the cell does actually contain a formula (a formula starts with the =
character), not a number or text, then the formula length limit applies.
I couldn't find formula length limit in the Limits and Specifications
part of Help, but it was 1024 characters in Excel 2000.
Same for Excel 2003...

See under the "Calculation Specifications" section.
Just found this....

which says the limit has been raised from 1K to 8K, so I guess that means
8192 characters.
