Most business owners, agency leads, and sales teams already live in spreadsheets. Solver turns those grids into decision engines. In Google Sheets, you can bolt on tools like OpenSolver to maximize profit or minimize cost under real-world constraints. In Excel, the built-in Solver add-in lets you frame complex questions as objective cells, decision variables, and constraints, then search thousands of combinations in seconds.Where it breaks down is repetition. Every new campaign, region, or pricing test means opening files, tweaking ranges, clicking 'Solve', saving results, and documenting what changed. That is exactly the kind of high-precision, low-creativity work an AI computer agent excels at.Imagine your agent opening Google Sheets and Excel, loading fresh data, running Solver across dozens of scenarios, labeling each run with date, assumptions, and outcome, then posting a summary to your CRM or Slack. While the agent iterates, you stay focused on strategy: which scenario to ship, not how to click your way there.
### 1. Manual ways to use Solver in Google Sheets and ExcelBefore you automate anything, you need to understand the traditional workflow. Think of this as the playbook you’ll later hand to your AI agent.**A. Manual Solver in Google Sheets (via add-on like OpenSolver)**1. Open your Google Sheet with the model you want to optimize.2. Install a Solver-style add-on: - Go to `Extensions > Add-ons > Get add-ons`. - Search for 'OpenSolver' or 'Solver'. - Click into the listing and press 'Install', then grant permissions. - See Google’s add-on help: https://support.google.com/docs/answer/93639733. Set up your model: - Choose an *objective cell* (for example, total profit). - Mark *decision variable* cells (like quantity to produce, budget per channel). - Add formulas that calculate constraints (inventory, budget, minimum ROAS, etc.).4. Launch the add-on from `Extensions > [Your Solver Add-on] > Start`.5. In the sidebar, select: - Objective cell. - Maximize / Minimize / Value. - Decision variable range. - Constraints (e.g. B2:B5 >= 0, C10 <= 100000).6. Click 'Solve' and wait for the add-on to change your decision cells.7. Inspect the result, accept or revert, then manually note assumptions and outcomes on another tab.**B. Manual Solver in Excel (built-in add-in)**1. Make sure Solver is enabled: - Go to `File > Options > Add-ins`. - At the bottom, choose 'Excel Add-ins' and click 'Go'. - Check 'Solver Add-in' and click 'OK'. - Official guide: https://support.microsoft.com/office/load-the-solver-add-in-in-excel-612926fc-d53b-46b4-872c-e24772f078ca2. Build your model: - One objective cell with a formula (e.g. total margin). - Decision variables: cells Solver can change. - Constraint cells: formulas that link to limits.3. Open Solver: `Data > Solver`.4. Configure: - Set Objective: select the objective cell. - To: Max, Min, or Value Of. - By Changing Variable Cells: select the variable range. - Add constraints one by one (e.g. D2:D10 <= F2:F10, B2:B10 >= 0, integer constraints where required).5. Choose solving method (GRG Nonlinear, Simplex LP, Evolutionary) based on whether your relationships are linear.6. Click 'Solve', then choose whether to keep Solver solution.7. Save a Scenario so you can compare multiple runs: in Solver, click 'Load/Save' or use 'Scenario Manager'.This manual approach is powerful but fragile: one mistaken range or forgotten constraint, and a busy marketer or founder has to re-run everything.### 2. No-code automation for Solver workflowsOnce you know the clicks, you can layer light automation on top. This doesn’t remove Solver’s dialogs, but it reduces all the surrounding busywork: data prep, logging, and reporting.**A. Triggered Solver models around your data refresh (Google Sheets)**1. Store raw data (ad spend, leads, inventory) on a 'Data' tab, fed by tools like Google Analytics, ad platform exports, or no-code connectors.2. Keep your optimization model on a separate 'Model' tab that references the Data tab.3. Use Apps Script (no-code-ish) or a marketplace connector to refresh data on a schedule. - Apps Script overview: https://developers.google.com/apps-script/guides/sheets4. Use your Solver add-on manually, but: - Create a 'Run Log' sheet with columns: Date, Scenario, Key inputs, Result. - After each Solver run, use a small Apps Script custom menu to automatically copy current inputs and outputs into the log.You’re still clicking 'Solve', but the logging is automated and repeatable, making it much easier for an AI agent to pick up later.**B. Excel macros to semi-automate Solver runs**1. Turn on the Developer tab: see https://support.microsoft.com/office/show-the-developer-tab-247c9caa-6168-456b-82c3-48c0e22f0e872. Record a macro that: - Opens Solver. - Loads a specific Solver model configuration. - Clicks 'Solve' and then 'Keep Solver Solution'.3. Save this macro in your workbook as 'RunCampaignSolver'.4. Add a button on the sheet linked to the macro.Now a team member only clicks a button instead of configuring Solver from scratch.**C. Scenario templates for non-technical teammates**1. In either Sheets or Excel, create a 'Scenario' input area with clearly labeled cells: target CPA, minimum margin, max inventory, etc.2. Use formulas to connect this section to the model tab that Solver will reference.3. Document in a top-left note: '1) Edit scenario cells. 2) Press Run Solver button. 3) Read results on Summary tab.'You’ve now turned Solver into a productized template. This makes it dramatically easier to hand off to an AI agent later, because the structure is consistent.### 3. Running Solver at scale with an AI agentHere’s where a Simular AI computer agent changes the game for operators, agencies, and sales teams.**A. AI agent as your Solver operator**Imagine you run weekly pricing optimization across 40 product groups in both Google Sheets and Excel models. Instead of an analyst babysitting each file:1. You document the workflow once: open file, refresh data, run Solver, log result, export summary.2. In Simular Pro, you configure an agent to: - Launch the required apps (browser for Google Sheets, desktop for Excel). - Navigate to each spreadsheet or workbook. - Detect the 'Run Solver' macro button in Excel, or the Solver add-on menu in Sheets. - Execute the steps exactly as a human would: select ranges, click 'Solve', wait, store outputs.3. Connect the agent to a webhook so, after all runs, it posts a dashboard summary to your reporting tool or Slack channel.**Pros:**- Eliminates repetitive, error-prone clicking.- Works across desktop Excel, browser-based Google Sheets, and even other tools in the same run.- Transparent execution: you can replay every step the agent took.**Cons:**- You must design stable templates: consistent sheet names and ranges.- Initial onboarding effort to teach the agent the exact flow.**B. Multi-scenario Solver simulations overnight**For agencies and revenue teams, the real power is scenario volume. With an AI agent:1. Create a table of scenarios in Google Sheets or Excel (different budgets, prices, lead-cost assumptions).2. Script your model so it reads one scenario at a time into the Solver inputs.3. In Simular, instruct your agent to: - Loop through each scenario row. - Update the input cells accordingly. - Run Solver. - Append the result to a 'Scenario Results' sheet.4. Schedule this as a nightly or weekly job.You wake up to a scenario matrix ranked by objective (profit, revenue, ROAS) instead of spending hours experimenting.**Pros:**- Turns Solver from a one-off tool into a decision pipeline.- Allows non-technical founders and marketers to benefit from optimization at scale.**Cons:**- More moving parts: your scenarios table, Solver model, and agent loop must stay in sync.- Requires some governance so someone owns verifying that the model’s still valid as the business changes.
Start by enabling Solver in each environment. In Excel, go to File > Options > Add-ins. At the bottom, select 'Excel Add-ins' and click 'Go'. Check 'Solver Add-in' and press 'OK'. You’ll now see 'Solver' in the Data tab. Build your model with a clear objective cell (such as total profit), decision variable cells (quantities, budget splits), and constraint formulas (inventory, budget caps, minimum ROI). Then open Data > Solver, set the objective, select the variable range, add constraints, choose a solving method (Simplex LP for linear models), and click 'Solve'.In Google Sheets there’s no native Solver, so you install an add-on. Open your sheet, choose Extensions > Add-ons > Get add-ons and search for 'OpenSolver' or 'Solver'. Install it and grant permissions (see Google’s docs at https://support.google.com/docs/answer/9363973). Then follow the add-on’s sidebar: pick an objective cell, decision range, and constraints, and click its 'Solve' button. Always test on a copy first so you can safely inspect how Solver changes your decision cells.
Imagine you manage ad spend across Google, Meta, and LinkedIn. In either Google Sheets or Excel, create a table with channels in rows and columns for spend, expected CPA, and conversion volume. Define an objective cell that calculates total leads or revenue based on spend and CPA. Make the spend cells your decision variables. Then add constraints: total spend must equal your budget, spend per channel must be above a minimum threshold, and maybe a maximum CPA.In Excel, enable Solver as an add-in, open Data > Solver, set the objective cell to 'Max' for leads or revenue, and add the constraints. In Google Sheets, install a Solver-style add-on and configure the same objective and constraints through its sidebar. Once you’ve validated that Solver finds sensible allocations, document the steps. This documentation becomes the script you can hand off to a Simular AI agent later so it can refresh data, re-run Solver weekly, and push an updated budget recommendation without you touching a spreadsheet.
Most Solver failures come from model setup rather than the algorithm. First, separate inputs, calculations, and outputs into clear sections or tabs. Use one objective cell that references your calculation area, and never hardcode numbers inside that formula – always point to input cells. Second, double-check that your decision variables only appear where they should. If you accidentally use them in a constraint formula in the wrong way, Solver may misinterpret the model or fail to converge.Third, ensure constraints reflect business reality and are not contradictory. For example, don’t set minimum margin higher than what’s mathematically possible. In Excel’s Solver, start with Simplex LP if your formulas are linear; switch to GRG Nonlinear or Evolutionary only if needed. In Sheets add-ons, look for a 'linear' mode when appropriate. Finally, keep a 'baseline' scenario saved. If you’re planning to automate with an AI agent like Simular, lock this baseline in a separate sheet so the agent always has a known-good configuration to revert to during testing.
Consistency is your friend. First, standardize sheet names, ranges, and labels. Always keep your objective cell and decision range in the same location, even as models evolve. In Excel, save your Solver configuration as part of the workbook and, if possible, wrap it in a macro so users only click a 'Run Solver' button. In Google Sheets, structure the model so your Solver add-on can always rely on the same named ranges or cell coordinates.Second, log every run. Create a 'Solver Runs' sheet with columns for timestamp, scenario parameters, and key results. After each run, manually copy values into this log. Once you’re confident, you can automate this with Excel macros or Apps Script in Sheets. This log becomes invaluable if an AI agent is involved: it can check whether a new run looks wildly different from prior runs and, if so, pause and notify you. With this discipline, running Solver daily or weekly becomes a safe, repeatable process rather than a fragile experiment.
Start by treating Solver like a micro-service that lives in your spreadsheets. Define a clear, repeatable workflow: refresh data, choose scenario, run Solver, log result, and publish a summary. Write this as a checklist and test it yourself until it’s boring and predictable. Then move to automation.With a Simular AI computer agent, you can record or describe each step: open a specific Google Sheet, wait for data to refresh, trigger the Solver add-on, confirm the updated decision cells, and copy results into a summary tab or separate Excel file. The same agent can then open Excel on your desktop, run the built-in Solver add-in with a macro, and export charts or CSVs. Because Simular Pro is designed for production-grade reliability and transparent execution, you can inspect every click the agent makes.The payoff: marketers get optimized budgets each Monday; agencies can re-price retainers across dozens of clients; founders can review multiple pricing or hiring plans – all without manually touching Solver.
