@SamSurya,

 

In a formula you can use an expression like:

 

IF 
regex_match([Field],"[A-Za-z]+") THEN "Alpha"	ELSEIF
regex_match([Field],"\d+") THEN "Numeric"	ELSEIF
regex_match([Field],"[A-Za-z0-9]+") THEN "AlphaNumeric"	ELSEIF
regex_match([Field],"[^A-Z,a-z]+") THEN "Printable Characters"	ELSEIF
regex_match([Field],"[^ -~]+") THEN "Non-Printable Characters"	ELSE
"Unknown"
ENDIF

 

If you use a multi-field formula, you can check the type with [_CurrentFieldType_].

 

Cheers,

Formula (31) Parse Error at char(0): Formula: tried to apply string operator to numeric value (REGEX_MATCH) (Expression #1)

Hi @SamSurya 

 

Please use tostring() function

if regex_match(tostring([Field]),"\d+") THEN "Numeric"

Thank  you Mark & Devi. this works, however, not sure if 0 is treated under /d as in case 0's it's moving to else part which is Unkown
