Learn the basics of regular expressions and their use when managing tax information in your organization
Regular expressions are a method you can use to limit what information input can be validated by Meeting+.
Using regular expressions will help you eliminate user errors when filling out important tax fields in the Meeting+ add-in and ensures that there are no invalid tax field entries in your Meeting+ settlement data.
Setting up custom regular expressions can be very technical and may require help from your IT department. We recommend the use of this tool when trying to create a custom regular expression.
