I tried to follow other suggestions but I could not get past the 1st hyphen.

I have data in alpha numeric of 7 characters and I want to insert the hyphen the same for all [after the 2nd, 4th & 5th character]

These are bin locations and in the cell read: A101A01 and without retyping 3800 cells I want to change to: A1-01-A-01.

The location of the letters and numbers is always the same place if that is needed.

Thanks folks.
