Hey so I got a cell that is 12000x1 and inside this cell I got some strings that are 2x1 or 3x1. I want to delete this string but get the messages from there and put them inside the cell. Is there any function that let me do this?

Yes, I see it. What do you want todo with these strings? Remove them or replace them? In the latter case: by what?

I want to get the messages from inside like the other lines

Your description is not clear yet. I dare to guess:

% Input (thanks Adam):
C = {"sdfsd"; "dare"; ["abs";"ses"]; "erwe"; "serwe"; ...
    ["444";"wer"]; "adrwed"; ["ee";"vse";"xxx"]; "sered"}
% Wanted output:
C = {"sdfsd"; "dare"; "abs";"ses"; "erwe"; "serwe"; ...
    "444"; "wer"; "adrwed"; "ee"; "vse"; "xxx"; "sered"}
% Solution:
D = cellstr(cat(1, C{:}))

If your goal is to simply be able to read those lines, use cellfun to identify elements of cell array "C" that have more than one row of strings and then use cellfun again to transpose those rows.

Create demo data - you can see that there are 3 elements of C that are 2x1 or 3x1 string arrays

C = {"sdfsd"; "dare"; ["abs";"ses"]; "erwe"; "serwe"; ...
    ["444";"wer"]; "adrwed"; ["ee";"vse";"xxx"]; "sered"}
C = 9×1 cell array
    {["sdfsd" ]}
    {["dare"  ]}
    {2×1 string}
    {["erwe"  ]}
    {["serwe" ]}
    {2×1 string}
    {["adrwed"]}
    {3×1 string}
    {["sered" ]}

Transpose mutli-rows

[nRows, ~] = cellfun(@size,C);
isMultiRow = nRows>1; 
C(isMultiRow) = cellfun(@(a) {a'}, C(isMultiRow))
C = 9×1 cell array
    {["sdfsd"               ]}
    {["dare"                ]}
    {["abs"    "ses"        ]}
    {["erwe"                ]}
    {["serwe"               ]}
    {["444"    "wer"        ]}
    {["adrwed"              ]}
    {["ee"    "vse"    "xxx"]}
    {["sered"               ]}

If you'd like to join those strings into 1, replace the line above with this line.

C(isMultiRow) = cellfun(@(a) {strjoin(a,' ')}, C(isMultiRow))
C = 9×1 cell array
    {["sdfsd"     ]}
    {["dare"      ]}
    {["abs ses"   ]}
    {["erwe"      ]}
    {["serwe"     ]}
    {["444 wer"   ]}
    {["adrwed"    ]}
    {["ee vse xxx"]}
    {["sered"     ]}

It would be easy to help you, if you provide an example with an output for a specific input. I ask for this repeatedly, but you show us screen shots and rough explanations only. "get the messages from inside like the other lines" is not clear enough and an image showing "2x1 string" does not help also.

"join the strings into one and then split into two lines" - why do you want to join them before splitting? This sounds, like you have a specific purpose for thi, but I cannot guess this detail.

"found the function strsplit but it gives me the error using it" - post your code an a complete copy of the error message. Remember, that the readers in the forum have no idea of what you are doing, but this is required to assist you.

Adam did you the favour to create an example for the input:

C = {"sdfsd"; "dare"; ["abs";"ses"]; "erwe"; "serwe"; ...
    ["444";"wer"]; "adrwed"; ["ee";"vse";"xxx"]; "sered"}

Now it is your turn to show us, what you want to get. Post it as code, which produces the wanted output, not as description like "in a different line".
