I have excellent command on Google Sheets. I have completed complex projects before involving Userforms, Macros, formulas, graphs etc.
For instance
- Upload and Manage Videos in Vimeo using JSON API in google sheets
- A system to extract data from Google Forms and mail from gmail and save attachments to google drive
- Twitter functionality like retweet, auto-tweet, and so on
You can see the reviews of the same in my profile
