Using the field header "x<23" in a function

Question

I have a field [x<23].

I would like to use that field name in a function (e.g. Text.Split([x<23]," ").

I have tried entering each character of the field name as a unicode decimal using #() and Character.FromNumber only to return the error: "Invalid Identifier."

How to I enter the field name "x<23" (exclusive of quotations) into an M fuction?

Answer 1

Try

[#"x<23"] 

You can just add column ... custom column ... and choose your column and it would provide the code sample for the column name
