Short Summary

Main recommendation: To find the most frequently occurring text value in a column, wrap a MATCH array (converting each text item to its first-occurrence position) inside the MODE function, then use INDEX to return the text, as shared by Bill (the online Excel teammate) in this video. The method works around MODE only accepting numbers, and the video also covers mixed data and multiple modes.

Key Points

  • MODE and MODE.MULT only accept numbers, so text must first be converted to numeric positions using MATCH with exact match (0).
  • Entering MATCH's lookup value as the entire range creates a function argument array operation that returns a position for every item, showing the position of each item's first occurrence.
  • Wrapping the MATCH array in MODE returns the position of the most frequent item; INDEX then pulls the matching text from that position.
  • For mixed data with blanks or numbers, an IF(ISTEXT(...)) filter removes the #N/A and numeric results before MODE runs, and the formula must be entered with Control+Shift+Enter.
  • When several values tie, MODE.MULT returns all tied positions, which can be extracted with SMALL and INDEX as the formula is copied down.

Details Worth Noting

  • Concrete instructions:
    • Check the simple approach first: use COUNTIFS with the whole criteria range (anchored with F4) to count each category, which shows which is most frequent.
    • For a single-cell formula, the core structure is: =INDEX(column, MODE(MATCH(column, column, 0))). Select the MATCH part and press F9 to verify the numeric positions.
    • For mixed data, use: =INDEX(column, MODE(IF(ISTEXT(MATCH(column, column, 0)), MATCH(column, column, 0)))) and enter it with Control+Shift+Enter.
    • For multiple modes, first count them with COUNT(MODE.MULT(MATCH(column, column, 0))). Then, in each row, use SMALL(MODE.MULT(...), n) to get the nth position and wrap it in INDEX to return the text. Use IF(count < n, "", formula) to hide extra rows when the number of modes changes.
    • Use F4 to lock references and Control+Enter with a double-click on the fill handle to copy formulas down quickly.
  • The MODE function returns only the first mode when there is a tie; MODE.MULT is needed for all modes.
  • The speaker notes that the single-cell MODE/MATCH formula (without IF) did not need Control+Shift+Enter, even though he expected it would, but the IF-based mixed-data formula does require Control+Shift+Enter.

Bottom Line

Converting text to positions with MATCH is the key trick that lets MODE find the most frequent text value, and INDEX turns that position back into the word.
