Can’t write xlsx file to another folder

Please help me, the programmer who made this software is gone and now I’m in trouble: the program opens an xlsx file, inserts some data inside and saves it with another name, I need this file to be saved in a specific directory, can anyone help me? Thank you!

        wb.save (filename  = self.filename)

Answer

In wb.save (filename = self.filename) you can provide any path you need in place of self.filename.

The filename that it gets is defined in the parse method, specifically on following lines:

self.tag = xml_data.attrib['name']
if self.tag == None or self.tag == "":
    self.tag = "noname"
self.filename = self.tag + ".xlsx" 

From there, you can prepend the contents of self.filename with the desired path. Like this for example:

self.filename = "/desired/path/" + self.tag + ".xlsx" # On Linux

or

self.filename = "C:/desired/path/" + self.tag + ".xlsx" # On Windows
