How to convert text "JAN" into number 1?

[Eric]

Does anyone have any suggestions on how to convert text "JAN" into number 1?
Does excel have any built in function to do it?
For all the months' symbol into numbers
"JAN" into 1
...
"MAR" into 3
...
"DEC" into 12

Does anyone have any suggestions?
Thanks in advance for any suggestions
Eric

Expand this formula:

=LOOKUP(A1,{"JAN","FEB"},{1,2})

for the remaining months

If your abbreviations are nice, you could use a formula like:

=month("1"&A1)

If your abbreviations aren't nice, it won't work.

Hello Eric,

In UK you can use
=MONTH("1/"&A1)

In USA it is probably
=MONTH(A1&"/1")

Regards,
Bernd

The values in the lookup vector have to be in ascending order, so you
need to sort the months like this to have the formula working:

=LOOKUP(A1,{"APR","AUG","DEC","FEB","JAN","JUL","JUN","MAR","MAY","NOV","OCT","SEP"},{4,8,12,2,1,7,6,3,5,11,10,9})

Hope this helps / Lars-Åke

,"MAR","MAY","NOV","OCT","SEP"},{4,8,12,2,1,7,6,3,5,11,10,9})

Easier and less error-prone:

=MATCH(A1,{"jan","feb","mar","apr","may","jun","jul","aug","sep","oct","nov","dec"},0)

Do you have any suggestions on how it works this way?

=MONTH(A1&1)

Just to add to David's response...

I'm amazed at how many different string formats excel can see as a date. It
comes in particularly handy when doing data|text to columns.
