Is the first character a number or letter
I need a formula that tells you if the first character in a string is
a number or a letter. Thanks Very Cunfused |
Answer: Is the first character a number or letter
Hi Very Confused,
You can use the following formula to determine if the first character in a string is a number or a letter: Formula:
You can replace "A1" in the formula with the cell reference that contains the string you want to check. |

Try something like this:
for a value in A1 B1: =ISNUMBER(--LEFT(A1,1)) That formula returns TRUE if the 1st char is a number, otherwise FALSE Does that help? *********** Regards, Ron XL2002, WinXP "bactfarmer" wrote: I need a formula that tells you if the first character in a string is a number or a letter.

I need a formula that tells you if the first character in a string is a number or a letter. One way, at least for English letters, =IF(s<"",LOOKUP(CODE(s),{0;48;58;65;81;97;123}, {"other";"numeral";"other";"letter";"other";"lette r";"other"}),"") |

try something like =ISNUMBER(LEFT(A1,1)*1) where A1 is the string you are evaluating. Multiplying the leftmost character by 1 seems to be necessary to keep it from being considered a text string that looks like a number. Good luck.

=IF(ISERR(LEFT(A1,1)*1),"letter","number")

This is a bit more involved, but this will also tell you if the first
character is something other than a letter or number. =IF(A1="","",IF(AND(CODE(LEFT(A1,1))=48,CODE(LEFT (A1,1))<=57),"Number",IF(OR(AND(CODE(LEFT(A1,1))= 65,CODE(LEFT(A1,1))<=90),AND(CODE(LEFT(A1,1))=97, CODE(LEFT(A1,1))<=122)),"Letter","Other"))) HTH, Elkar "bactfarmer" wrote: I need a formula that tells you if the first character in a string is a number or a letter.

Thanks All! I got it too work. I'm starting to like Excel!

Hi there...
i am looking forward to know is there any formula to know if a value is alphanumeric too, as well as its a number or a letter... Take care...

Could you give some examples of what you mean?

You could make a slight modification to Harlan's formula which returned true
for alphanumeric, =IF(COUNT(SEARCH(LEFT(A1,1),"0123456789ABCDEFGHIJK LMNOPQRSTUVWXYZ")),"alphan umeric","not") BTW, when I tested on my test data, which I created using the formula =CHAR(ROW())&"123" (in a1:a255,) I got some false positives and not sure why, and was not able to eliminate the false positives. They weren't the same false positives as I was getting with my failed attempt using =IF(OR(AND(LEFT(A1,1)="a",LEFT(A1,1)<="z"),AND(LE FT(A1,1)="A",LEFT(A1,1)<= "Z")),"letter",IF(ISNUMBER(--(LEFT(A1,1))),"numeral","other")) (for the earlier request. Note, I had read Ron Coderre's reply earlier which is probably how I came up with the isnumber... part of the formula.) BTW, on Harlan's earlier formula, it appears 81 should in actuality be 91: =IF(LEFT(A1,1)<"",LOOKUP(CODE(LEFT(A1,1)),{0;48;5 8;65;91;97;123},{"other";" numeral";"other";"letter";"other";"letter";"other" }),"") -- Kevin Vaughn "Sunrays17" wrote in message ps.com...
