Missing formulas

[NateWilcox]

I'm trying to extract data between characters and many sites reference TEXTBEFORE and TEXTAFTER. when I try to instigate said formulas, the result is #NAME?

I searched through the formulas in Excel 365 and cannot find either formula. My company provides Office 365 subscription and I'm on the most recent release. However, these formulas are not new from the research I've done. 

Any recommendations for adding missing formulas?

I'm trying to extract data between brackets in column "A" to Column "E". The issue I have is that 2 pieces of data are between brackets

blah blah blah info [Data to extract] (useless info) [more useless info]

Is there even a way to do this?

Update your Microsoft Office applications.

There was a similar discussion earlier in the year

why doesn't Excel recognize the TEXTBEFORE() and TEXTAFTER() functions when I try to use them? - Mic...

Even if you are on a semi-annual update cycle, the function should reach you soon.

I defined the Lambda function

TEXTBETWEENλ(text, open, close, instance)

= LET(
    partStrings, TEXTAFTER(text, open,instance),
    extracted,   TEXTBEFORE(partStrings,close),
    extracted
  )

Note: the AFE inserts the Lambda and the parameters into the definition.

The worksheet function then becomes

= TEXTBETWEENλ(text, "(", ")",-1 )

to return the right-most occurrence.

Thanks! Just updated and the formulas aren't there yet.
Forgive my intermediate Excel knowledge. How do I implement the lambda function in your first string as a formula?

That looks very phishy...
