Why Sheets, Excel and AI

When your pipeline looks healthy but renewals keep slipping, the real problem usually hides in scattered signals: logins in one system, NPS in another, invoices in a third. A customer health score template in Google Sheets or Excel pulls those threads together into a single, readable story: who is adopting, who is stuck, and who is primed for expansion.Templates work because they force clarity. You define the drivers (adoption, value, support risk, commercial risk), agree on thresholds, and make the math visible. No black-box models—just a living scorecard your team can challenge and improve.But maintaining that clarity manually is brutal. That’s where delegating to an AI computer agent changes the game. Instead of a CSM spending hours hunting metrics, your agent logs into tools, copies fresh data into Google Sheets or Excel, recalculates scores, flags accounts that cross risk thresholds, and even drafts follow-up tasks. The template becomes a real-time command center, continuously refreshed by automation while your humans focus on conversations, not cells.

How to Build Customer Health Scores in Sheets & Excel

### 1. Traditional, manual ways to build a customer health score**1. Start with a simple scoring sheet in Google Sheets** 1. Go to Google Sheets and create a new spreadsheet ([how to](https://support.google.com/docs/answer/6000292?hl=en)). 2. Create columns: `Customer`, `MRR`, `Logins/30d`, `Key Features Used`, `Tickets/30d`, `NPS`, `Health Score`, `Health Band`. 3. Define a 0–100 scale and assign weights, e.g.: Usage 40, Support 20, NPS 20, Revenue 20. 4. Add normalized sub-scores with formulas, e.g. in `Usage_Score`: `=MIN(40, (C2/20)*40)` 5. In `Health Score`, sum them up: `=SUM(F2:I2)` 6. Use conditional formatting to color bands (red/yellow/green) ([guide](https://support.google.com/docs/answer/78413?hl=en)).**2. Mirror the model for finance in Excel** 1. Create a new workbook ([instructions](https://support.microsoft.com/en-us/office/create-a-new-workbook-5bd3d193-3c3c-4f82-9b32-3b0d11ce564a)). 2. Replicate the same columns so Sheets and Excel stay in sync. 3. Build formulas with clear named ranges for weights (e.g. `UsageWeight`, `NPSWeight`) ([formulas overview](https://support.microsoft.com/en-us/office/overview-of-formulas-in-excel-ecfdc708-9162-49e8-b993-c311f47ca173)). 4. Add conditional formatting for bands ([how-to](https://support.microsoft.com/en-us/office/use-conditional-formatting-to-highlight-information-78d2c008-2a0a-4b11-9e6b-8a19d9f81b80)). 5. Create a pivot table by CSM, segment, or industry to see portfolio health.**3. Manually update data each week** 1. Export usage reports from your product, tickets from support, invoices from billing/CRM. 2. Copy-paste or import CSVs into dedicated tabs (`Usage_Raw`, `Support_Raw`, etc.). 3. Use `VLOOKUP` / `XLOOKUP` in Google Sheets or Excel to join on `Customer ID`. 4. Refresh formulas and review top red accounts in a weekly CSM meeting.**Pros (manual):** very transparent, great for building the first version, everyone sees the logic. **Cons:** time-consuming, error-prone copy-paste, scores get stale quickly.---### 2. No-code automation methods**4. Automate inputs into Google Sheets with native connectors** 1. Use your CRM’s native Google Sheets export or scheduled report. 2. Connect apps like HubSpot or Salesforce to Google Sheets via add-ons or tools like Zapier/Make. 3. Send events (new NPS response, ticket created, invoice paid) into your `*_Raw` tabs. 4. Keep your scoring formulas unchanged—only the raw data updates. 5. Add a summary dashboard tab with `QUERY`, charts, and slicers ([Google Sheets functions](https://support.google.com/docs/answer/3093340?hl=en)).**5. Use Excel + Power Query for automated refresh** 1. Store your Excel health score workbook in OneDrive or SharePoint. 2. Use **Data > Get Data** to connect to CSV exports, databases, or OData feeds (Power Query). 3. Transform/clean data once, then save the query. 4. Hit **Refresh All** to pull the latest usage, support, and revenue data on demand. 5. Pin your health dashboard to Microsoft Teams or Power BI if needed.**6. Trigger alerts with no-code tools** 1. In Google Sheets, create a `Trigger_Log` tab that flags when `Health Score` falls below a threshold. 2. Use Zapier/Make to watch that sheet: on new row or status change, send a Slack/Teams/Email alert to the owner. 3. For Excel, connect Power Automate to your workbook: when a table row is updated and `Health_Band = "At Risk"`, create a task in your CRM.**Pros (no-code):** less manual work, refreshable data, basic alerts, still readable. **Cons:** still reliant on APIs and connectors, brittle zaps, and someone has to maintain the automation.---### 3. Scaling with AI agents (Simular) at desktop levelThis is where you stop babysitting spreadsheets and let an AI computer agent operate them like a diligent analyst.**7. Agent-run data aggregation into Sheets and Excel** Imagine a Simular AI agent with a morning routine: log into your product analytics, support tool, CRM, billing, then update both Google Sheets and Excel without any APIs.- You configure Simular Pro to open your browser, navigate to each tool, export or copy data, clean it, and paste into `*_Raw` tabs in Google Sheets and Excel. - Because Simular’s agents operate across the desktop, they can also handle multi-factor auth and different file formats. - Every action is transparent and inspectable, so you can see exactly how scores are refreshed.**Pros:** works even when APIs are limited, handles multi-step workflows, production-grade reliability over thousands of actions. **Cons:** initial setup requires careful recording of steps; you’ll want a stable layout for your tools.**8. Agent-driven scoring, QA, and playbook triggers** Next, give your agent the job of *stewarding* the model, not just feeding it.- Schedule the Simular AI agent to open the latest Google Sheet, recalc formulas, and scan for accounts that changed band. - Have it write a short narrative summary for each flagged account in a `Notes` column (e.g. "Health dropped from 78 to 52 due to rising tickets and lower logins"). - In Excel, the agent can refresh Power Query connections, update pivots, export a "Red Accounts" tab and upload it or paste it into your CRM or task manager.**Pros:** you get context-rich commentary, not just numbers; your team receives ready-to-use lists and notes. **Cons:** requires clear instructions and guardrails so the agent doesn’t overwrite formulas or structure.**9. Agent-orchestrated, multi-tool health ops** Finally, let your AI agent own the full weekly "health ops" ritual:1. Refresh all data sources and scoring sheets. 2. Export top at-risk and top-growth lists. 3. Draft personalized outreach emails per account into your CRM or email platform. 4. Update a leadership dashboard (e.g. slides or a summary doc).Because Simular’s agents are built for long, multi-thousand-step workflows, they can move through browser tabs, desktop apps, and cloud tools reliably—something no single no-code integration can cover end to end.**Pros:** end-to-end automation of an otherwise 3–5 hour weekly process; humans focus on strategy and customer calls. **Cons:** you’ll want a short observation period to monitor and tweak behavior before fully hands-off operation.
