What is Google Apps Script?

Google Apps Script is Google's JavaScript-based platform for building business applications that connect Google Workspace. It lets you add custom menus, dialogs and sidebars to Docs, Sheets and Forms, write custom functions and macros for Sheets, automate Gmail, Calendar and Drive, publish web apps, and build add-ons for the Google Workspace Marketplace. Scripts are written in a browser-based editor, saved in Drive and run on Google's servers, so there is nothing to install or host.

Premier Cloud, a Google Cloud Premier Partner, designs, builds and supports Apps Script solutions for organizations that want to take manual work out of Google Workspace. Looking for something bigger? Pair Apps Script with Cloud Run and BigQuery through our process automation services.

What we build

What we build with Apps Script

From a single spreadsheet macro to a company-wide add-on, our Google Cloud engineers design, build, test and hand over Apps Script solutions your team can run and maintain. Bigger workflows can combine Apps Script with Cloud Run and BigQuery through our process automation services.

Workflow automation

Automate approvals, notifications, reports and data entry across Gmail, Sheets, Forms, Drive and Calendar.

Custom add-ons

Sidebars and menus inside Gmail, Docs and Sheets that put your processes where people already work, such as an invoice reader that moves invoice data from Gmail into Sheets and BigQuery.

AI-powered scripts

Call Gemini from Apps Script to read documents, extract data and draft content, like turning PDF invoices into structured rows.

Integrations and APIs

Connect Google Workspace to BigQuery, your CRM and other business systems through REST APIs and Google Cloud.

Document and report generation

Generate Docs, Slides and PDFs from Sheets or Forms data, and send scheduled reports by email.

Gmail, Drive and Calendar automation

Label and route messages, save attachments to Drive, manage sharing and create calendar events from your data.

Sheets functions, menus and sidebars

Custom functions, menus, dialogs and sidebars that make a spreadsheet behave like the internal tool you need.

Web apps and internal portals

Publish lightweight web apps, standalone or embedded in Google Sites, for requests, lookups and simple dashboards.

Google Apps Script + Gemini

Add Gemini to your Google Workspace automations

Apps Script can call Gemini models through Google Cloud, so a script can read a document, classify an email, extract fields from a PDF or draft a reply, then write the result back to Sheets, Docs or Gmail. Google's Vertex AI service for Apps Script needs a Google Cloud project with billing turned on and the API enabled, which we can set up with you. Not sure you need code? Google Workspace Studio covers simple no-code flows, and we will tell you which tool fits. See an example in our guide to extracting PDF data with Gemini and Apps Script.

  • Classify and summarize Gmail messages
  • Draft replies and documents with a human in the loop

Platform limits

Built around Apps Script's limits

Apps Script runs inside Google's published quotas. Today:

6 minmaximum run time for a single execution
6 hourstotal trigger runtime per day for Google Workspace accounts
100,000URL fetch calls per day for Google Workspace accounts

Google can change these limits without notice, so we design around them with batching, queues and, for heavy jobs, Google Cloud services such as Cloud Run and BigQuery, and keep Apps Script for the logic that belongs in Google Workspace. See Google's current Apps Script quotas.

FAQ

Common questions about Google Apps Script development, limits and how we work with your team.

Apps Script automates work across Gmail, Calendar and Drive, adds custom menus, dialogs and sidebars to Docs, Sheets and Forms, powers custom Sheets functions and macros, publishes web apps, builds Google Workspace add-ons and connects Google Workspace to outside systems through APIs.

Apps Script is JavaScript, so anything beyond a simple macro takes development skills to build and maintain. Our Google Cloud engineers build, test and document the solution so your team can run it without writing code.

Google publishes quotas for Apps Script. Today a single execution can run for up to 6 minutes, and Google Workspace accounts get 6 hours of total trigger runtime and 100,000 URL fetch calls per day. Google can change these quotas at any time, so we design around them and move heavy workloads to Google Cloud when needed.

Yes. Apps Script can call Gemini models through Google's Vertex AI service for Apps Script, which requires a Google Cloud project with billing turned on and the API enabled. We use it for tasks like extracting data from documents, classifying email and drafting content. See our Gemini services for the wider picture.

Google Workspace Studio (formerly Flows) lets any user build visual "if this happens, then do that" workflows in Google Workspace. Apps Script suits custom logic, integrations and add-ons. We can help you choose, or use both.

Nothing is installed. Apps Script is written in a browser-based editor, saved in Drive and runs on Google's servers inside your Google Workspace environment.

We deploy with documentation and admin controls so the solution stays secure and easy to maintain, and we offer optional ongoing support. Book a discovery call to scope your project.
