I have a string of text that needs to be formatted and saved as a txt file. The string is in this format:

,1,1880802442166,1,751702411341,1,751702411358,1,751702411365,1,751702411372,1,751702411389,1,751702459060,1,751702459077,1,751702459084,3,751702459091,1,751702459107,1,751702459114,2,751702459121,1,751702459145...

It needs to be output in this format:

,1,1880802442166

,1,751702411341

,1,751702411358

,1,751702411365

,1,751702411372

,1,751702411389

,1,751702459060

,1,751702459077

,1,751702459084

,3,751702459091

,1,751702459107

,1,751702459114

,2,751702459121

,1,751702459145...

It's for an inventory list that was recorded in the wrong format.

Thanks in advance,

Nick

I needed a blank line between each in value in the list, but I just added an extra

\r\n

in

fprintf(fid,'%s \r\n',c{k,:})

Thanks
