Hello Sir/Ma'am,
I completely understand your request and its not a very uncommon one, I have 3+ years of experience developing on Google App Script, and I assure of a quality tool in the promised timeline, following the standard industry practices for robustness and modularity.
I will be making use of the UrlFetch API provided in Google App Script and convert the received JSON data into desired custom format ( spreadsheet / xls ), my tool can be deployed with a timely trigger to fetch and store the data into google sheets, without your intervention.
Looking forward to work with you.
Warm Regards,
Murtaza Sadriwala
