You can use std::reverse:

QString numbers{QLatin1String("1234")};
std::reverse(numbers.begin(),numbers.end());
qDebug() << numbers;

@BORHAN-CO. said in Qt Swap numbers places in text:

but numbers are in text documents

How your documents are formatted ?
like this?

// doc.txt

"1234"
"1234"
"1234"
"1234"
