Here is a quick reference for Excel column letter to number mapping. Many times I needed to find the column number associated with a column letter in order to use it in Excel Macro. For a lazy developer like me, It is very time consuming ðŸ˜‰ to use my Math skill to get the answer so I created this quick reference lookup for myself.

brilliant job, I often need the reverse but your table gives me that option as I can just look up the other way

Thank you, such a simple table but very, very helpful.

I agree that this is really useful. I have take the opportunity to extend the process to Column XFD – the last in my version of Excel.

A copy of the VB Code is available at https://www.linkedin.com/feed/update/urn:li:activity:6644160098514141186

Thank you so much! This is so helpful ðŸ™‚

Or you can just make quick Mathematical formula based on the position of input.

eg.

ABC: 26*26*(A=1) + 26*(B=2) + (C=3) = 731.

CH: 26*(C=3) + (H=8) = 86.

very brilliant

thanks to share

vipul jhaveri

you should stop using vlookup and use xlookup. There you can just reference “CH” instead of 86

Thank you! I ran out of fingers trying to figure out how to reference Column CH in my VLOOKUP. ðŸ™‚

So simple and yet so useful–bless you, Mr. Monpara!
