Formula to enter to extract the text within ( ) in a text string
Example: "My Text String (MTS)" and extract or return MTS
Currently the "(XXX)" is always at the end of the text string
Using MS Excel 2002

Are those the only parenthesis?

=SUBSTITUTE(MID(A1,FIND("(",A1)+1,255),")","")

replace A1 with your cell

Thank you ever so much Peo -
WORKED GREAT!!!!!
On going through a long list it turned out that there were cases
with additional parenthesis -
But the prenethesis which I want to extract the text from is the
one on the furthest right.
For example I found one that looked like:
"My Text String (XPYZ (MTS)" in addition
"My Text String (MTS)"
and I still want to return MTS from both examples

If there always will be a space before the parenthesis
with the string you want to extract

=SUBSTITUTE(MID(A1,FIND("^^",SUBSTITUTE(A1,"
","^^",LEN(A1)-LEN(SUBSTITUTE(A1," ",""))))+2,255),")","")

Thanks Peo
Worked Great!!!!
But in addition to "My Text String (MTS)" I also found
"My Text String (ADT (MTS)"
For which I would still like to return "MTS"

You could download and install Longre's free morefunc.xll add-in from
http://xcell05.free.fr and use this Regular Expression formula to extract the
alphanumeric text string within the last set of "(...)"

Easy to modify if that is not precisely what you want. And fairly easy to
write a UDF to mimic it.

Also, this will not work on strings longer than 255 characters -- if that might
be the case, post back and I will put up an equivalent UDF.


=REGEX.SUBSTITUTE(A1,".*\((\w+)\).*$","[1]")

Or use assertions.

=REGEX.MID(A1,"(?<=\()[^()]*(?=\))")

Also begs the question whether to be as inclusive as possible within
the parentheses. If so, [^()]* matches more substrings than \w+.

If you are going to use assertions that way, per the OP's requirements, you
need to ensure you return the last match.

Given, for example:

My Text String (XPYZ) (MTS)) in addition

your REGEX.MID returns (XPYZ),

So, I would use:

=REGEX.MID(A1,"(?<=\()[^()]*(?=\))",-1) or
=REGEX.MID(A1,"(?<=\()[^()]+(?=\)[^(]*$)")

But I've been purposely trying to avoid using lookbehind assertions since they
are not supported in VBScript. And often enough, it has happened that I've had
to switch to VBA.


Also begs the question whether to be as inclusive as possible within
the parentheses. If so, [^()]* matches more substrings than \w+.

Absolutely correct, and a good point to make explicitly. (That is why, in my
description, I wrote "alphanumeric text string".)

Now, having written all that, and thought about it some more, it appears as if
the look-behind assertion may not even be necessary!

For example:

[^()]+(?=\)[^(]*$)

or even:

\w+(?=\)[^(]*$)

or

[A-Z]+(?=\)[^(]*$)

All seem to work, and would work in either PCRE or VBScript.

Thanks.

Thank You "ALL", Peo, Ron & Harlen
ALL super helpful: I am learnin a lot -
Back to Peo's original suggestion - I finally figured out what
everything in the formula =SUBSTITUTE(MID(A1,FIND("(",A1)+1,255),")","") and
will use this and those suggestions form Ron and Harlen in the future - BUT
what does the 255 refer to in the above example. I also just found another
useful information site: http://www.techonthenet.com/excel/formulas/

AGAIN THANKS ALL!!!!! REALLY I sometimes spend hours trying to figure this
stuff out on my own and you all are a super HELP!!!!

Fair point.

=REGEX.MID(A1,"(?<=\()[^()]*(?=\))",-1) *or

Best.

=REGEX.MID(A1,"(?<=\()[^()]+(?=\)[^(]*$)")

Less efficient.

For long string support? You could handle them with VBScript by using
a regex to check the match pattern itself. If you find a look behind
assertion, convert it to a separate expression, e.g.,

(?<=\()[^()]*(?=\)) - \([^()]*(?=\))

use the modified regex to get the desired substring from the source
string, then trim off the bit matching the look behind assertion. It'd
make the wrapper function more complicated, but you could add support
for look behind assertions this way.

Now, having written all that, and thought about it some more, it appears as if
the look-behind assertion may not even be necessary!

For example:

[^()]+(?=\)[^(]*$)

or even:

\w+(?=\)[^(]*$)

or

[A-Z]+(?=\)[^(]*$)

All seem to work, and would work in either PCRE or VBScript.

All would fail if there were an unmatched left parenthesis to the
right of all other parentheses. Not necessarily an idle consideration
since your example string

My Text String (XPYZ) (MTS)) in addition

has unbalanced parentheses. All may fail if there were only a right
parenthesis with no left parentheses if the OP wanted "" returned in
such cases.

It tells you how many characters to return after the last space, I didn't
think you would have a
string parenthesis included that would be more than that :) So it is just an
arbitrary number
and very rarely would a last string (since you told us it was always the
last word) exceed
that. I am sure putting 20 would be enough.

Yes. That and also dealing with capturing groups (.submatches) in certain
instances.

You could handle them with VBScript by using
a regex to check the match pattern itself. If you find a look behind
assertion, convert it to a separate expression, e.g.,

(?<=\()[^()]*(?=\)) - \([^()]*(?=\))

Interesting approach. I like the flexibility. I'll have to think about
implementing that one of these days.

Good point. I had not considered something like:

"My Text String XPYZ (MTS) ( in addition"
