time format change

New Contributor

I received a text (tab delim) file with times in it.   I opened in Excel and need to fix the times.
Some times are in h:mm and work correctly in Excel.
Other are just :mm and Excel will not see them as times no matter how I format the column.   If I retype them as 0:mm then it will work correctly.

is there any quick way to reformat the entries to get the 0 in front of the entries that are just colon minutes?

I have tried formatting the column with the time format.  - didn't work
I have tried a custom format of Use a custom time format of 00\:00 which would didn't work as expected as either since the colon is already in the column.

Hi. The right approach is to import the text file with Power Query. Opening the text file directly with excel will give a lot problems. There are lots of tutorials about PQ on YouTube.
