Spreadsheet Automation

Spreadsheet Automation

Overview

Google Sheets isn't just for budgets and lists. With the right formulas, Apps Script, and integrations, it becomes a database, CRM, project tracker, analytics dashboard, and workflow engine — all in one free tool. This playbook shows you how to build production-grade systems in Sheets that replace $50-500/month SaaS tools.

Step 1: Identify What to Automate in Sheets

Not every workflow belongs in Sheets. Here's when Sheets is the right tool.

Good use cases for Sheets automation:

• Data collection from multiple sources (form responses, API data, manual input) → centralize in one place
• Lightweight databases (customer lists, inventory, project tracker) → under 10K rows, basic relationships
• Dashboards and reporting (pull data from other tools, visualize, share)
• Workflow triggers (when row added/updated → send email, create task, update another sheet)
• Data transformation (clean, format, enrich data from messy sources)

Bad use cases (use a real database or tool instead):

• Heavy computation (millions of rows, complex queries) → use BigQuery, Airtable, or SQL database
• Real-time collaboration with 10+ concurrent users → use Airtable, Notion, or dedicated project management tool
• Mission-critical data that can't afford accidental deletion → use a real database with backups and version control
• Complex relational data (many-to-many relationships) → use Airtable or proper database

Audit your current manual work (10 min):

1. List tasks you do in Sheets manually (copy/paste, data entry, formatting, updating other sheets)
2. Which tasks are repetitive? (daily, weekly, triggered by an event)
3. Which tasks take 5+ minutes each time?
4. Which tasks have clear logic? ("If this, then that")

Low-hanging fruit checklist:

• Auto-populate cells based on other cells (formulas)
• Pull data from external sources (APIs, other sheets, web scraping)
• Auto-format or clean data (remove duplicates, standardize dates, extract values)
• Send notifications when conditions are met (email alerts, Slack messages)
• Create charts or dashboards that update automatically
• Sync data between Sheets and other tools (CRM, project management, accounting)

Step 2: Master Advanced Formulas (No Code Required)

Most Sheets automation starts here. Master these formulas and you can build 80% of what you need without Apps Script.

Core Formula Reference

QUERY (SQL-like queries in Sheets):

=QUERY(A1:D100, "SELECT A, B, C WHERE D > 1000 ORDER BY C DESC")

• Use for: Filter, sort, group, and summarize data
• Syntax: SELECT [columns] WHERE [condition] ORDER BY [column] LIMIT [number]
• Example: Pull all customers with orders > $1,000, sorted by date

IMPORTRANGE (pull data from other sheets):

=IMPORTRANGE("spreadsheet_url", "Sheet1!A1:D100")

• Use for: Centralize data from multiple sheets into one master sheet
• Setup: First time, you need to approve access (click "Allow access" when prompted)
• Example: Pull sales data from regional team sheets into one master dashboard

ARRAYFORMULA (apply formula to entire column):

=ARRAYFORMULA(IF(A2:A="",,B2:B*C2:C))

• Use for: Auto-calculate for all rows (no dragging formulas down)
• Example: Auto-multiply quantity × price for every new row added

VLOOKUP / XLOOKUP (lookup values from another table):

=VLOOKUP(A2, Sheet2!A:B, 2, FALSE)

• Use for: Match and pull related data (e.g., customer name → pull their email)
• XLOOKUP (newer): More flexible, can search left-to-right or right-to-left

FILTER (dynamic filtering):

=FILTER(A2:D100, D2:D100>1000, C2:C100="Active")

• Use for: Show only rows that meet criteria (updates automatically when data changes)
• Example: Show only active customers with revenue > $1,000

UNIQUE (remove duplicates):

=UNIQUE(A2:A100)

• Use for: Extract unique values from a list (auto-updates when source changes)

REGEXEXTRACT (extract patterns from text):

=REGEXEXTRACT(A2, "[0-9]{3}-[0-9]{3}-[0-9]{4}")

• Use for: Pull phone numbers, emails, URLs, or any pattern from messy text
• Example: Extract domain from email addresses

IMPORTXML / IMPORTHTML (scrape web data):

=IMPORTXML("https://example.com", "//h1")

• Use for: Pull live data from websites (prices, headlines, tables)
• Example: Track competitor pricing automatically

Step 3: Build Multi-Sheet Systems

Single-sheet solutions are limited. Real power comes from connecting multiple sheets into a system.

System architecture pattern:

SHEET 1: Data Entry (input form or manual entry)
  ↓
SHEET 2: Master Database (cleaned, validated, enriched)
  ↓
SHEET 3: Dashboard (charts, summaries, insights)
  ↓
SHEET 4: Exports/Reports (formatted for sharing)

Example: Simple CRM in Sheets

Sheet 1: Lead Entry Form

• Columns: Name, Email, Company, Source, Date Added
• Use: Google Form → auto-populates this sheet
• Validation: Email format check, required fields

Sheet 2: Master Lead Database

• Pulls from Sheet 1 using IMPORTRANGE or direct reference
• Adds enrichment: Status (New/Contacted/Qualified/Closed), Last Contact Date, Notes
• Formula example: =IF(ISBLANK(D2), "New", D2) (auto-set status to "New" if empty)

Sheet 3: Dashboard

• Total leads: =COUNTA(MasterDB!A2:A)
• Leads this week: =COUNTIF(MasterDB!E2:E, ">="&TODAY()-7)
• Conversion rate: =COUNTIF(MasterDB!D2:D, "Closed")/COUNTA(MasterDB!A2:A)
• Chart: Leads by source (pie chart)

Sheet 4: Weekly Report

• Formula: =FILTER(MasterDB!A2:E, MasterDB!E2:E>=TODAY()-7)
• Auto-pull this week's leads for review meeting

Key principles:

• One sheet = one purpose (don't mix input, storage, and display)
• Use formulas to connect sheets (avoid manual copy/paste)
• Protect important sheets (prevent accidental edits)

Step 4: Learn Apps Script Basics (Google's JavaScript for Sheets)

Apps Script lets you do things formulas can't: send emails, make API calls, create custom menus, run code on a schedule.

When to use Apps Script:

• Formulas can't do it (sending emails, hitting APIs, complex logic)
• You need automation to run on a schedule (every hour, daily, weekly)
• You want custom functions or menu items

How to access Apps Script:

1. Open your Google Sheet
2. Extensions → Apps Script
3. Write code in the editor

Example 1: Send Email Alert When New Row Added

function onEdit(e) {
  var sheet = e.source.getActiveSheet();
  
  // Only run on "Lead Entry" sheet
  if (sheet.getName() !== "Lead Entry Form") return;
  
  // Get edited row and column
  var row = e.range.getRow();
  var col = e.range.getColumn();
  
  // If new row added (row > 1 to skip header)
  if (row > 1 && col === 1) {
    var name = sheet.getRange(row, 1).getValue();
    var email = sheet.getRange(row, 2).getValue();
    
    // Send email notification
    MailApp.sendEmail({
      to: "you@example.com",
      subject: "New Lead: " + name,
      body: "Name: " + name + "\nEmail: " + email
    });
  }
}

How to set up:

1. Paste code into Apps Script editor
2. Save (Ctrl/Cmd + S)
3. Set up trigger: Triggers (clock icon) → Add Trigger → onEdit → From spreadsheet → On edit → Save
4. Authorize permissions when prompted

Example 2: Fetch Data from API and Write to Sheet

function fetchAPIData() {
  var url = "https://api.example.com/data";
  var options = {
    "method": "GET",
    "headers": {
      "Authorization": "Bearer YOUR_API_KEY"
    }
  };
  
  var response = UrlFetchApp.fetch(url, options);
  var data = JSON.parse(response.getContentText());
  
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("API Data");
  
  // Clear existing data
  sheet.clear();
  
  // Write headers
  sheet.appendRow(["ID", "Name", "Value"]);
  
  // Write data rows
  data.forEach(function(item) {
    sheet.appendRow([item.id, item.name, item.value]);
  });
}

How to set up:

1. Paste code, replace url and YOUR_API_KEY
2. Run once manually to test (click Run button)
3. Set up time-based trigger: Triggers → Add Trigger → fetchAPIData → Time-driven → Hour timer → Every hour
