Hi, I want to read in a excel with the first cell of each row of the form:
2020-09-02 00:00:00.7770000,"OLW218","Pickling","Water lock Off-time PV (Sec)",105,,,"Good"
(this is all in one cell)
and replace it with a vector of the form
[0.777,"OLW218","Pickling","Water lock Off-time PV (Sec)",105,"Good"]
or a form where I can for example have: vector(6) = "Good".
If I use xlsread or save the excel as txt file it is imported as a cell {"2020-09-02 00:00:00.7770000,"OLW218","Pickling","Water lock Off-time PV (Sec)",105,,,"Good""}. I tried the split command, but I can't get the result I want.

Hi dpb
That is an option, but there are a lot of files and I don't want to change them all manually. Creating them differently might be the easiest option, but I don't control that haha.

Two of many ways to deal with the cellstr --
As string array
>> S=string(split(C,',')); S=S(S~="")
S =
6×1 string array
"2020-09-02 00:00:00.7770000"
""OLW218""
""Pickling""
""Water lock Off-time PV (Sec)""
"105"
""Good""
>>
or as cellstr
>> CC(~cellfun(@isempty,CC))
ans =
6×1 cell array
{'2020-09-02 00:00:00.7770000' }
{'"OLW218"' }
{'"Pickling"' }
{'"Water lock Off-time PV (Sec)"'}
{'105' }
{'"Good"' }
>>
Alternatively, use textscan and convert the fields directly. Will leave as "exercise for student"

Hi dpb,
Thanks for the help. The problem I had with this solution is that ' "Good" ' or ""Good"" cannot be used for example as if S(end) == "Good" ...
The problem actually solved itself by using readtable instead of xlsread.
