STRIM

[Rnkhch]

STRIM is a complete "space" removal solution to conveniently manage leading, trailing, or all spaces within a string

STRIM stands for "space trim". STRIM allows for conveniently specifying what type of spaces to remove form a string. The choices are: leading spaces, trailing spaces, all spaces, and TRIM-style space removal (where all spaces except one space in between words are removed).

=LAMBDA(text,space_removal_type,
   SWITCH(space_removal_type,
       "leading",
          LET(a,LEN(text),
             (RIGHT(text,a-(MATCH(TRUE,INDEX(CODE(MID(text,ROW(INDIRECT("1:"&a)),1))<>32,),0)-1)))),
       "trailing",
          LET(a,LEN(text),
             (LEFT(text,a-(a-AGGREGATE(14,6,ROW(INDIRECT("1:"&a))/(CODE(MID(text,ROW(INDIRECT("1:"&a)),1))<>32),1))))),
       "all",
          SUBSTITUTE(text," ",""),
       "trim",
          TRIM(text)
    )
)

This work is based on the discussion at the following thread:

How to count the total number of leading and trailing spaces in cells?

Hello, I'm trying to come up with a way to count leading and trailing spaces in cells. I have seen posts discussing ways of trimming such spaces, but I didn't see anything about counting them. (The reason I need this is that it will help me identify the source software from which some of my...

Thanks a lot!
From your argument description:
"space_removal_type: Required. Specifies the type of space removal and takes one of four arguments: "leading", removes leading spaces; "trailing", removes trailing spaces; "all", removes all spaces; "trim", removes all spaces except one space in between words"
No mention of middle spaces plus is mentioning "one of four arguments". That's why I did not do it in the first place. My bad that I did not follow your examples.

Anyhow, here is the function that does it all.
SPTRIM(ar,[ka]) calls ST
ar: any array containing any data type
[ka]: array of arguments or single values
- if ka omitted=> 0 => TRIM op
- if ka 1 => remove leading spaces
- if ka -1 => remove trailing spaces
- if ka 2 => remove middle spaces
- if ka=3 => remove all spaces

=LAMBDA(ar, [ka],
    LET(
        a, IFERROR(ar, 0),
        j, IF(ISOMITTED(ka), 0, ka),
        f, LAMBDA(t, k, MAP(t, LAMBDA(x, IF(ISTEXT(x), ST(x, k), x)))),
        r, REDUCE(a, j, f),
        IF(ar = "", "", r)
    )
)

where ST:

=LAMBDA(t, k,
    LET(
        b, TRIM(t),
        l, LEN(t),
        a, LEN(TEXTBEFORE(t, LEFT(b))),
        c, LEN(TEXTAFTER(t, RIGHT(b), -1)),
        SWITCH(k, -1, LEFT(t, l - c), 1, RIGHT(t, l - a), 0, b, 2, REPT(" ", a) & b & REPT(" ", c), SUBSTITUTE(t, " ", ""))
    )
)

Thanks much @Xlambda

Just got a chance to check back here as I was away all of last week. Your updated function works very well. I'll work on integrating it with STRIM hopefully during the coming week.

The helper function PLSA (and its components) in my STRIM just ensures that if the wrong type and/or number of parameter(s) are entered, the function returns a single #N/A (just like any native Excel function would do). This is to ensure that no erroneous output is generated by accident if the user mistakenly puts in the wrong argument or if the argument comes from another operation embedded in the parameter (the yellow/red highlights for SPTRIM vs. the green highlights for STRIM in the XL2BB below). (I put in entirely wrong arguments in the bottom table I always do that to my own functions to make sure that they crash with any wrong argument.)

Updated code: adds two new arguments for the "space_removal_type" parameter, in response to feedback I received: "newline" and "condense"

A) The "newline" argument removes all line breaks, i.e. CHAR(10), from the input text

Note that the "all" argument does not remove line breaks even though it may appear that they are removed. You can verify this by copying the result, pasting value in another cell, double-clicking within this new cell, and hitting ENTER. You will now see all the available line breaks. I have done this in the attached XL2BB.

B) The "condense" argument removes all spaces as well as line breaks and completely reduces the input text to a single line with no spaces left


The easiest way to get this function and all my other functions is to download my template from my signature below. Enjoy using/testing.

                  "trailing",MAP(t,LAMBDA(x,LET(y,LEN(x),LEFT(x,y-(y-AGGREGATE(14,6,ROW(INDIRECT("1:"&y))/(CODE(MID(x,ROW(INDIRECT("1:"&y)),1))<>32),1)))))),

                  "condense",MAP(t,LAMBDA(x,SUBSTITUTE(SUBSTITUTE(x,CHAR(10),"")," ","")))
               ),
               i
            )
         )
      )
   )
)

The code for the helper functions has not changes, so I'm not including them here again.
