How do I add a line to an existing file. This should append to the
existing data in the excel file, which was saved previously.
Hi Jason and all,
I have seen this.. my question is there a way to append to a excel
file which has been closed. Any specific modes which can be added to
the sheet so that it adds a line to the data which was return in some
earlier running of the program.
If you are talking about an XLS file and not a CSV then it's a highly
structured object, and you can't just "stick bits on the end" with any
expectation that Excel will know what to do with the new data. The most
likely outcomes would be Excel either complaining the file format is
invalid or ignoring the extra data.
If it's a CSV file, then f = open(file, "a") should do it.
