G-Connector for Salesforce makes the data from Salesforce actionable and easy to see for anyone in our organization. Additionally, I have used it to create dashboards, screens, automated reporting, and so much more that just would not be as accessible or analyze-able if it was stuck in Salesforce or I relied on manual exports.
Adding Googles Table Capture on the Chrome browser makes for an amazing tool to grab and digest data!
Using google sheets an its csv sharing feauture, I'm able to dynamically update the offering of my ecommerce website, without having to manage a complex CMS or a database.
Every day, someone update the catalog with next day's products, 5 minutes later the website is up to date.
Yet Another Mail Merge add-on has been a good way to send bulk emails using Google sheet.
SuperMetrics for Google Sheets helps save me and my team a ton of time pulling data across several analytics and marketing platforms (Google Analytics, DoubleClick, MOZ, etc.). There can be some hiccups depending on the complexity of the queries but overall it's been super helpful.
The Jira Cloud for sheets add-on is extremely useful and allows custom reporting (much more than what's available natively in Jira) from any number of projects.
Jira Cloud for Sheets is my favorite as it lets you to report however the way I want as I feel the reporting features or Jira can be improved. Alsoc not everyone in the organization is using Jira so Google Sheets let me share one single link with everyone and they can see an up to date dashboard on what’s going on.
PS: second favorite would be draw.io as beinf a product guy, it let’s me draw all soft of flows, wireframes, etc
With no doubt, Google Table Capture which makes my life so much easier!
On so many occasions I've tried to copy tables to Excel and Google Sheets and it's messed up all the formatting...
