Copy formulas across ranges

Copy formulas across ranges in Microsoft Excel — with the four heights of help laid out: do it now, make it easier for the next person to accept, work out the right move when you are stuck, and learn the pattern so it stops coming back.

The four heights

The same task, four distances: today's deadline, the next reviewer, the stuck moment, the pattern.

Copy the formula in cell F12 across to F12:Z12 and then down through row 200 so every row uses the same calculation. After copying, check three random rows—15, 88 and 172—to confirm relative references adjusted and totals on the summary sheet updated.

Improve — make it easier to accept

Before I fill the range with this formula, make it safe to copy. Change any references that must stay fixed to absolute where appropriate, convert volatile INDIRECT or hard-coded sheet names to stable references, and add a quick validation row that flags when copied formulas return errors. Then fill across and down.

Decide — diagnose the stuck moment

I dragged a formula across and a whole block shows the same value instead of recalculating per column.

I just copied the formula from column F across to column Z and every cell shows the identical result, which suggests references didn't shift as expected. I don't know if the original used absolute references or if I pasted values by mistake. What immediate tests should I run to identify whether the issue is locked references or a paste operation, and how do I recover the correct formulas without manual re-entry?

Become — change the pattern

Every time I copy formulas across ranges some rows end up with broken references or static values.

When I copy formulas across and down in large ranges, I often introduce absolute-reference mistakes or accidentally paste values, which creates subtle errors that surface in reports. What habitual checks and a short pre-copy checklist will stop these copy mistakes and save me rework on every model update?
