Here's one way to do it in a formula: use this website ( ascii-code.com ) to look up the ASCII equivalent of each character. It turns out to be this: / 47 \ 92 * 42 ? 63 " 34 < 60 > 62 | 124
Then use a FIND formula to look for the ASCII equivalent. I tried the SEARCH formula but it appears to use the ASCII equivalent of * as a wildcard and returns a false positive; the FIND formula does not. If the user's entry is in cell F10, write this formula in another cell: =IF(OR(ISNUMBER(FIND(CHAR(47),F10,1)),ISNUMBER(FIND(CHAR(92),F10,1)),ISNUMBER(FIND(CHAR(42),F10,1)),ISNUMBER(FIND(CHAR(63),F10,1)),ISNUMBER(FIND(CHAR(34),F10,1)),ISNUMBER(FIND(CHAR(60),F10,1)),ISNUMBER(FIND(CHAR(62),F10,1)),ISNUMBER(FIND(CHAR(124),F10,1))),"Illegal character in filename, please try again.","Filename OK.") That's a little bulky but gets the job done. -- Join official Facebook page of this forum @ https://www.facebook.com/discussexcel FORUM RULES 1) Use concise, accurate thread titles.
