Hello,
Is it possible to read a specific range1 in a csv file AND write a specific range2 in the same file WITHOUT altering the range1
Like an 'append' option for csvwrite or xlswrite
prefere csv rather than xlsx (had many problems with xlsx format before)
Thank you

dlmwrite() offers the option -append . Note, however, that this is restricted to writing additional rows immediately after all existing rows.
writematrix() offers the option 'writemode', 'append' . Note, however, that this is restricted to writing additional rows immediately after all existing rows.
The technology of the representation of text files does not permit selected parts of a file to be overwritten -- not without rewriting the entire file.
