Hi, I have a workbook that has 1 column (Column A) with 8000 Rows. Each Cell contains a string of words ranging from 1 word to 100 words. I am looking for a formula that can create a list of most common words (keywords) in each cell across the column. Ideally, i would like to know the most repeated words in the entire column.

Can this be done with a formula or can it only be done via VBA, if so, can someone please assist me with the code or formula.

Much Appreciated.

Try this for strings of words in column "A":-

Can you give an example of your data in column "A".
The results will show in a message box, you can have them in a cell if required.

Hi Mick,

Thanks for the above. Works great. Can i ask 1 last favour. Please can you display the results in Column B in top 50 Words instead of the Top Word. So instead of " Change the "1" to 2,3-- for second and third largest", I would like a list of top 50 words. Thanks.
