excel, how to use a own reference (dynamic) for a range cells to append a conditional validation. Check HEX

Question

EXCEL

I try to figure out HOW to add for a range of cells a validation for HEX-decimal input.

DATA VALIDATION >> CUSTOM >> For CELL E16, it works fine like this

=IF(AND(LEN(E16)<=2;ISNUMBER(HEX2DEC(E16)));TRUE;FALSE)

So to reference to the cell self can be done as following (use CHAR(64 + -> 65 is A and COLUMN() *gives a number A -> 1 *

=(CONCATENATE(CHAR(64+COLUMN());ROW()))

So I thought

=IF(AND(LEN(INDIRECT((CONCATENATE(CHAR(64+COLUMN());ROW()))))<=2;ISNUMBER(HEX2DEC(INDIRECT((CONCATENATE(CHAR(64+COLUMN());ROW()))))));TRUE;FALSE)

Has somebody an idea to make it easy to do it for a big range ...

Thanks

Answer 1

You have the answer already:

• apply your posted data validation to cell E16
• copy cell E16
• select a block of other cells
• PasteSpecial > Validation

The formula will auto-adjust over the range of pasted cells.
