    Hi,

    I need to process a CSV file and do some formatting on certain columns such as padding characters and replace some text within the column. So I think below are the specific tasks to achieve. Line ending should not be altered.

    • Read header and identify the colums positions to be modified.
    • Read a line and do the modification in the identified column positions.

    I already have obtained the column positions correctly from header. How can I modify columns while reading a single line?

    Indika.

      Hi and welcome
      Maybe something like
      QString line= file.readline();
      QStringList Fields=line.split(",");
      now
      each field is in the list
      Fields[0], Fields[1]
      so Fields[4]="changed";
      then put them back.
      line=Fields.join(",");
