Break a string of text (sentence or paragraph) at a space just < 50 in Excel


Can someone suggest a formula in Excel (2013) that will break a long string of text (like a sentence or paragraph) located in cell A1 into blocks (in column B) which:

        a) each have a length of < 50 characters and
        b) each are broken at the last space before 50 in order to avoid divided words?

For example, suppose the entry in cell A1 is as follows:
I receive lots of great help and solutions at Experts Exchange. It is a great resource and well worth the monthly fee.
This entry contains 118 characters and if broken into exactly 50-character segments in column B,  would appear as follows (with the number of characters shown in parentheses to the left):

(50)        B1 = I receive lots of great help and solutions at Expe
(50)        B2 = rts Exchange. It is a great resource and well wort
(18)        B3 = h the monthly fee.

I'm looking for a formula to paste in column B which, instead of inserting the break at exactly 50 characters, will identify and create the breaks at the last space just shy of 50:

(46)        B1 = I receive lots of great help and solutions at
(50)        B2 = Experts Exchange. It is a great resource and well
(22)        B3 = worth the monthly fee.

Note that when the breaks are made, the space at those locations is not lost. In the above example, a space is present after the words "at" and "well" in the first two segments respectively.

Also, it's clear that the formula will have to take into account the number of characters which end up up in each of the preceding cells.

Hello Steve,

I used this formula in B1

=IF(A1="","",LEFT(A1,LOOKUP(50,FIND(" ",A1&" ",ROW(INDIRECT("1:"&LEN(A1)))))))

then this one in C1 copied across as far as you need

=IF($A1="","",REPLACE(LEFT($A1,LOOKUP(50+SUMPRODUCT(LEN($B1:B1)),FIND(" ",$A1&" ",ROW(INDIRECT("1:"&LEN($A1)))))),1,SUMPRODUCT(LEN($B1:B1)),""))

Neither formula is an array formula and both should work in any version of excel from 2003

See attached example

Happy New Year!

regards, barry

PS to address neilsr's point. If you make the data in a table in Excel 2007 or later then you can add rows as you wish and the formulas will automatically populate the new rows (but obviously you need to include the formulas in enough columns to accommodate the maximum length of text).

What happens to the string of text entered in A2?
What is wrong with just word wrap in the cell and a higher Row height?

such complex evaluation is not easily done with a formula. This would require VBA, because there is a certain element of looping involved that a formula cannot provide.

I'm not even sure it can even be done with VBA, but I'm pretty sure that it's not possible with formulas.

PS. Happy New Year, Steve

pls try

MID($A$1,IFERROR(SUM(LEN(B$1:B1)),0)+1,LOOKUP(2^15,FIND(" ",MID($A$1,IFERROR(SUM(LEN(B$1:B1)),0)+1,50),ROW(INDIRECT("1:"&LEN(LEFT($A$1,50))))))),RIGHT($A$1,LEN($A$1)-IFERROR(SUM(LEN(B$1:B1)),0))),"")

as an array formula (Ctrl-Shift-Enter) in B2 then fill up b1 and fill down B6 or more

see example

I need to revise my definition of "not possible".
@teylin thank you for the compliment and "Guten Rutsch ins neue Jahr"

Like I said, what happens now when you have an entry in A1 And A2 And A3 And..... A24 ?
At what point does that become dynamic?  I assume that the questioner does not have a spreadsheet with JUST 1 row of data in it?

Thanks for the responses.

Barry, your solutions are always so…elegant.

Is that an adjective that can be applied to an Excel formula? I know it works for solutions and formulas in other disciplines so I assume it can be used here as well. :)

Thanks Steve,

Elegant works for me, I have certainly seen that adjective applied to excel formulas before.

Elegance and simplicity are two of the attributes I'm striving for - my New Year resolution is to add transparency, if possible, difficult with the complex formulas here........:)

Ohhh, I could use some transparency, "Barry". When it comes to your formulas, I often feel like Sisyphus

Steve, whenever "Barry" posts in a question I bow out. He always has the trump card, the perfect solution, the most elegant way. He's in a different universe. His blood is probably green.

Happy New year to you both,

cheers, teylyn
