I have a tab delimited text file with a column of dates. I copied and
pasted a selection of them below as a reference, there are in reality
over 35,000 rows of these dates.

These text dates must be converted to the following date format and
saved back into a text file as such:

mm/dd/yyyy

That includes leading zeroes in months and dates. E.g. 01/01/1999

To complicate matters, I need to explain the process to others.

Does anyone even know where I should begin?

THANK YOU,
- Chris
