Hosting a static HTML KPI dashboard with CustomJS

This workflow demonstrates how to automatically generate a weekly KPI dashboard from Google Sheets and host it as a live static HTML page using CustomJS.

Instead of manually building and updating dashboards, the workflow fetches KPI data, transforms it into JSON, and generates charts, tables, and KPI cards automatically. The hosted HTML page can be connected to a custom domain with one click.

The result is a fully interactive, production-ready KPI dashboard that updates weekly with minimal effort.

Why This Workflow?

Creating dashboards manually or passing raw sheet data to visualization tools is:

• time-consuming
• error-prone
• hard to automate

This workflow automates the process by converting sheet data into structured JSON and feeding it directly into a CustomJS HTML template, generating charts and tables automatically.

What This Workflow Does

• Fetches KPI metrics (Visitors, Leads, Demo Booked, Proposal Sent, Won) from Google Sheets
• Aggregates metrics by week and channel
• Converts the structured data into JSON for dashboard consumption
• Generates a static HTML page with KPI cards, charts, and tables
• Hosts the HTML page on CustomJS, optionally connected to a custom domain

All without manual intervention.
