Regex for bank account fields

Ask the Community Password Manager

Does anyone know how to specify lower or upper case ONLY matches that work in BW custom fields? Is this even possible?

Example: regex=^(rout).*$

The regex above matches:

  • routingnumber
  • Routing-Number
  • ROUT

I’m guessing the /i flag is hard-coded?

What if I want to match RoutingNumber but not match routingnumber?
