Irregular date calculations in large spreadsheet
I've been managing finances for a long time now in Excel. It has grown to 11.500 lines over a period of 20 years en recently my date calculations start to give #VALUE outcomes.
The formula in line 11498 is "=ALS(H11498<>"";H11498+7;D11498+14)"
The field H11498 contains a date (25-6-2025) and has cell characters of a date.
Similar formula in 11497 works like a charm.
11498, 11499 and 11500 give #VALUE
11501 works like a charm again.
Any ideas? Have I run out of Excels possibilities in regards to the size of the spreadsheet?

Either H11498 or D11498 is text. Check with ISTEXT().

Doublechecked but both fields are dates...

The output of ISTEXT() is either TRUE or FALSE not "dates".
