Help to Highlight a cell that has less than 5 characters

[Cendrinne]

Hello pro's,

Been searching Google and Bing, to find a script if a Word cell table has less then 5 characteres, highlight the cell.

Note, the table is normally of 2 columns but will have maybe over 5-10,000 rows. (A very long table). It would be easier for me to find such cell, if It's highlighted.

I've tried, but can't find a way yet.

Any insights? / Guidance?

Thanks in advance,
