Google Sheets & Apps Script

Google Sheets Automation and Apps Script Development

Turn Google Sheets into a working business tool: automatic reports, generated documents, emails and calendar events, data validation and connections to your other systems — all inside the Google Workspace you already use.

Overview

Your spreadsheet already runs part of the business

Google Sheets is often where quotes, schedules, orders and reports actually live. Google Apps Script — JavaScript that runs inside Google Workspace — can automate the repetitive work around those sheets: generating documents from rows, sending notifications, pulling data from APIs and building reports on a schedule.

We write Apps Script that is readable, handles errors, respects Google’s quotas and is organized so another developer could maintain it. Where a spreadsheet has become a critical system, we also add validation, protected ranges and audit logs so the data stays trustworthy.

Signs you need this service

  • You copy data between tabs or files every day or week.
  • Quotes, invoices or letters are built by hand from spreadsheet rows.
  • Reports are rebuilt from exports each Monday.
  • A script someone wrote years ago has stopped working.
  • Several people edit the same sheet and mistakes creep in.

Problems we solve

Spreadsheet problems we solve

Manual copy-and-paste

Moving rows between tabs and files, re-entering form responses and consolidating team sheets.

Hand-built documents

Quotes, certificates, invoices and reports created one by one instead of from a template.

Triggers that do not fire

Simple triggers used where installable triggers are needed, edits made by scripts or APIs that do not fire onEdit, or authorization that lapsed.

Scripts that time out

Loops that read and write one cell at a time and exceed execution time limits.

Unreliable shared sheets

Formulas overwritten, invalid entries and no record of who changed what.

Reporting delays

Numbers that are always a week old because building the report is manual.

What we build

What we build with Apps Script

Document & PDF generation

Google Docs or Slides templates filled from sheet data, saved as PDF in the right Drive folder and emailed.

Gmail & Calendar automation

Personalized emails, reminders and calendar events created from spreadsheet rows.

Scheduled jobs

Time-driven triggers for nightly imports, weekly reports and cleanup tasks.

Custom menus & sidebars

Buttons, menus and sidebars that give your team one-click actions inside the sheet.

API connections

UrlFetchApp integrations with CRMs, stores, payment systems and internal tools.

Web apps & forms

Lightweight HTML interfaces published as Apps Script web apps for internal data entry.

Sample workflow

Sample workflow: row to PDF quote

This example shows a common Apps Script pattern: a sales team fills in a row, and the script validates it, creates a quote document from a template, saves it to Drive and emails it.

A lock prevents two runs from processing the same row, and every result is written back to the sheet so the team can see what happened.

This is a hypothetical example built to explain the approach. It is not a description of a specific client project.

Press “Run the workflow” to watch the sample data move through each step.

How this workflow is specified

Trigger
Installable edit trigger on the status column, or a custom menu item for manual runs.
Applications
Google Sheets, Google Docs, Google Drive, Gmail.
Data inputs
Client name and email, line items, prices, discount, quote number, sales rep.
Processing logic
Validate row, lock processing, copy template, replace placeholders, export PDF, file it, send email, log result.
Expected outputs
A PDF quote in Drive, an email to the client and an updated status row.
Failure points
Missing template placeholders, invalid email, Gmail daily sending quotas, authorization required after script changes.
Error handling
try/catch per row, LockService to prevent double processing, error message written to the row and emailed to an admin.
Testing
Test rows with valid, missing and malformed data; run the quota-sensitive steps with small batches first.

Platforms & tools

Google Workspace services we use

Apps Script runs inside your Google account or Workspace domain, so data stays within Google unless a workflow is designed to send it elsewhere.

Implementation process

How an Apps Script project runs

  1. Discovery call

    We review the current process, the applications involved and the outcome you need, and ask for examples of real (or anonymized) records.

  2. Written scope

    You receive a short plan: trigger, steps, data fields, error handling, what is included and what is out of scope.

  3. Build

    We develop against a copy of your sheet with test data, using batch reads and writes, clear functions and configuration stored outside the code.

  4. Test

    Normal, edge and failure cases are tested — missing fields, duplicates, bad formats and authentication problems.

  5. Go live

    The workflow is switched on with you, checked against live activity and monitored during the first days.

  6. Handover

    You receive notes on how it works, where logs live, how to pause it and what to check if something changes.

Practical considerations

Practical considerations

  • Apps Script has execution time limits and daily quotas (for example, on emails sent and URL fetches) that vary by account type; large jobs are designed to run in batches.
  • Simple triggers such as onEdit do not run for changes made by scripts or the Sheets API, and cannot perform actions that require authorization.
  • Scripts run under the authority of the account that authorized them, so ownership and access should be planned before handover.
  • For very large datasets or many simultaneous users, a database-backed application may be a better long-term fit — we will tell you if that is the case.

Troubleshooting

When an Apps Script trigger stops working

Apps Script problems are usually visible in the Executions page of the script editor. We check:

  • Trigger type — simple versus installable, and who owns the installable trigger.
  • Execution log — errors, timeouts and the exact line that failed.
  • Authorization — whether new scopes need approval after code changes.
  • Quotas — whether a daily limit was reached.
  • Sheet changes — renamed tabs, moved columns or deleted named ranges.

FAQ

Google Sheets and Apps Script questions

Do we need Google Workspace, or does a free Google account work?

Apps Script works with both. Workspace accounts generally have higher quotas and better administration controls, which matters for business-critical automation.

Can you fix a script someone else wrote?

Yes. We review the code and execution history, fix the cause of the failure and improve reliability where needed — with notes explaining what changed.

Can Google Sheets connect to our CRM or store?

Usually. Apps Script can call most REST APIs, and many platforms can push data to Sheets through webhooks or automation tools.

Is a spreadsheet the right tool for our process?

Often it is a sensible and affordable choice. If your volume, security or multi-user needs exceed what Sheets handles well, we will say so and explain alternatives.

Who owns the code?

The script lives in your Google account or Workspace. You own it and have full access to the code.
