I have an existing query which produces the output I want. It works and the output is as needed.
I need to get the output as an excel sheet.
I can provide a sample of the target output
And provide access to both the query and the web page which currently displays the output.
I need a developer to work on writing this output to an Excel file.
Ideally, you should be using the PHPExcel library. Any developer with decent PHP experience can produce the output in 3-4 hours.
So, I will not be considering bids higher than a reasonable fee.
