Hi ,

Remember this Excel update from last year?

TRIMRANGE and the dot operator (.) quietly changed how we handle dynamic ranges.

The problem:

Your data grows → your formulas break → you fix ranges → repeat forever.

The solution:

Ranges that adjust automatically, no OFFSET or INDEX needed.

Before: Volatile OFFSET formulas that slow down your file.

After: =A1:.B10 resizes dynamically when your source data changes.

It works beautifully with XLOOKUP, data validation, and LAMBDAs; anywhere you reference ranges.
