CSV file handling with modification

indikaur

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(",");
