Hey Community!

Here’s my problem: I have users adding phone numbers to records. Problem is, the way the are inputting records doesn’t allow me to have Data validation. I need the number they input in a specific format, and I was hoping there might be a formula that could do this.

Format we need: 1 (XXX) XXX-XXXX

Inputs we might get (because users make mistakes) =

  • 1 xxx xxx xxxx
  • xxx xxx xxxx
  • xxxxxxxxxx
  • 1 (xxx) xxx xxxx
  • (xxx) xxx xxxx

What is important for us is there is the area code, aka, a “1” at the front of every number. I was thinking about creating a formula that adds a “1” at the start, but in the circumstances where a user does what we want, and adds a “1”, I don’t want to add it as it’d break it.

Does anyone know how to put a formula together that’ll do this?

PS,

Bonus points if you can ensure it looks “pretty” by formatting it in this way: 1 (XXX) XXX-XXXX

Right, there isn’t unfortunately and if you try to build a formula-only approach, it gets pretty ugly and convoluted. I think I needed three fields to achieve it when I tried it a few years ago. Perhaps there’s a formula geek amongst us that can whip one up.

COMMENTARY: Airtable should make it possible to perform data validation by supporting an option trigger to call into a script block and return the proper format or an error popup…

To get around this, I help clients perform a lot of data cleansing using the new script automation and script block features. Like this …

Thank you so much for putting this together. This will be incredibly helpful for ensuring our phone number data is usable.

You can set up a regex pattern rule in the DataGuard extension to prevent users from entering an incorrect telephone format and keep your data clean.
