CATEGORY - Excel Text Formulas VERSION - All Microsoft Excel Versions

Problem:

We want to search List1 (column A) for the value stored in cell B2 and retrieve the row numbers that correspond with every successful match.

Solution:

Use the SMALL, IF, and ROW functions as shown in the following Array formula:
{=SMALL(IF($A$2:$A$8=$B$2,ROW($A$2:$A$8),99999),ROW()-ROW($B$2)+1)}
Copy the formula down column C until 99999 is returned, which indicates that no further matches were found.

To apply Array formula:
Select the cell, press and simultaneously press .
