RegEx Validation

The information on this page relates to the new upgraded interface of the IConduct platform. To view information about the Classic version of the user interface, follow this link.

 

The RegEx Validation (short for Regular Expression Validation) option allows you to examine data in a source column and check whether it matches a specific format, thus affirming that the data is indeed valid.

 

For example, if you are checking whether the number listed in a phone number column can actually be used to dial a phone, you can use the RegEx Validation procedure to compare the content of the phone number column with an expression that is valid for phone numbers. In the destination column, you can place the result – whether the comparison shows that the phone number is valid, or not.

 

In the example below, we will use the following regular expression: ^[0-5]\d{2}-\d{3}-\d{4}$. This expression matches a hyphen separated phone number, of the form ANN-NNN-NNNN, where A is between 0 and 5 and N is between 0 and 9.

 

The result would be as follows:

 

Source Column Target Column

054-20000336

Valid

654-20000336

Invalid
