Write cell with struct to CSV

I have a cell of the form:

{1,1,"string", struct1}

{2,2,"string2",struct2}

.....

where struct1 may be: "string 1", value1

"string 2", value 2

I want to write the data to a csv file.

For now I am using fprintf, but no success with the struct data type.

fprintf(fid,'%g, %g, %s, %g\n',C{:,:})

From what I have I want to write to the CSV file something like this:

1,1,"string","struct 1 string1", struct 1 value1, "struct 1 string 2", struct 1 value 2, ... , etc

2,2,"string2","struct 2 string 1", struct 2 value 1, "struct 2 string 2", struct 2 value 2, ... , etc

...

So basicaly I want to include in the CSV also the field and the value for each structure, one by one on the same row.

Some help would by highly appreciated.

As a first step you can use fieldnames and struct2cell to unwind the struct itself. Then you will have to do the relevant conversions for each field.
