Set max character limit in Lists multi-line column

Hello, 

 

I have a multi-line column in a Microsoft Lists list and users are putting too much text in it. I would like to set a maximum character limit to prevent this (for example 500 characters). Can anybody advise how I would do this? 

Thanks

  • laser132217 the only out-of-the-box way to do this that I know of is to:

    • create the column as a single line of text column
    • set the validation settings to =LEN(yourcolumn)<500
    • change the column type to multiple lines of text

    The validation will still be applied even though it is now a multiple lines of text column.

      RobElliott I too would like to do this, I've tried adding the other columns to this formula, adding additional formulae, but can't get it to work - Riza24 did you find out how?

        found out how: 

         

        =AND(LEN([March Update])<500,(LEN([Jan Update])<500),(LEN([May Update])<500),(LEN([July Update])<500),(LEN([Sept Update])<500),(LEN([Nov Update])<500))

      Hi Rob,
      Thank you for your help. Can I clarify whether the validation is a column validation or a list validation?
      Thanks
