Regex to check if string is of exact length 7

shobhit_gupta

I have a requirement where I need to check if a first character of a string is an alphabet (a-z or A-Z), rest all characters should be numbers (0-9) and string length should be exactly equal to 7.

I am using regex tool to achieve this and used this expression: ([A-Za-z]+)([0-9]+)

With this, I am able to solve only the first two requirements but not the third one (length = 7). Can't wrap my head around this. Any suggestions are welcome. Thanks in advance.

Hey @shobhit_gupta Try this:

[A-Za-z]\d{6}

This states that the first character is a letter and the next 6 are numbers. As Regex Match always looks at the full string, this will only be true if the string is 7 characters long

Hope that helps,

Ollie

(if you want a more concise RegEx then:

\l\d{6}

with case insensitivity on will do the same thing)

Hi @shobhit_gupta

There is 2 ways to get result.

You can use Formula tool with length([Field]).

Many thanks
