I'm doing the following
excelFilename = 'someFile.xlsx';
structFieldnames = fieldnames(myStruct); % <--- where myStruct is your struct of data
for k = 1:length(structFieldnames)
fieldname = structFieldnames{k};
writecell(myheaderstruct.(fieldname), excelFilename, 'Sheet', sprintf('%s_matlab', fieldname)); % add header
writematrix(myStruct.(fieldname), excelFilename, 'Sheet', sprintf('%s_matlab', fieldname),'WriteMode','append');
end
Error:
Invalid parameter name: WriteMode.
If 'WriteMode','append' isn't included, the header is overwritten.
Could someone suggest why `WriteMode` isn't working here?
This
writematrix(data.(fieldname), excelFilename,'-append', 'Sheet', sprintf('%s_simgraph', fieldname));
also doesn't work.
Wrong number of arguments. A filename must be provided when supplying additional parameters, and each parameter name must be followed by a value.
I'm using 2109b.

Read the existing sheet as cell. Pad it or the new data to have the same number of columns. Put the two parts together. Write out to the sheet.
