Your Numbers don't behave (like numbers)
Niek Otten, May 11, 2006
Your numbers sort incorrectly, are not included in SUMs, cause #VALUE!
results in formulas, cannot be found in LOOKUPs, etc. In short:
Your Numbers look like Numbers, but they really are Text.
Sure! You formatted them as numbers, but alas, formatting afterwards doesn't
help. Believe me, they are Text!
Here's a checklist which will help you solve most known cases. Make a copy
of your workbook before trying! Always use Excel's ISNUMBER() function to
check your cells; maybe you solved your problem in the first step!
· Format an empty cell as Number. Enter the number 1 in it.
Edit>Copy.
Select your "numbers". Edit>Paste Special, check Multiply. Hopefully your
cells are "real" Numbers now
· If that doesn't help, there may be spaces in your "numbers". You
can use the LEN() function to compare the number of characters that Excel
sees in the cell with the number of characters you see. If you suspect
spaces, use Excel's TRIM() function to remove them
· If that doesn't help, there may be nonprintable characters in your
"numbers". You can use Excel's CLEAN() function to remove most of them
· If that doesn't help, there may be non-breaking spaces in your
"numbers" (mostly acquired from Web Pages). Use David McRitchie's TRIMALL()
function to remove them. It can be downloaded here:
