have tried this and it will not reformat the cell just leaves the
original data there 02:02:30:59 will not convert it
If you have a string "02:02:30:59" then reformatting will not work,
since the value is not a number.
Use Ron's answer:
=LEFT(A1,FIND(":",A1,1)-1)+TIMEVALUE(RIGHT(A1,8))
in an empty column, and copy down.
Then copy the converted values, select the original values and choose
Edit/Paste Special, selecting the Values radio button. Format with
Format/Cells/Number/Custom [h]:mm:ss.
If you instead want 50 hours 30 minutes 59 seconds, format as
Format/Cells/Number/Custom [hh] "hours" mm "minutes" ss "seconds"
