Excel changes one input and shows you one answer. Batch Runner runs your whole scenario table through the model and lays every result out beside the assumptions that produced it. One press. Every row calculated, every result recorded, your model put back as it was.
How it works, in five steps
Link the cells in your model that should change. Your model itself stays untouched.
On the control sheet, link to each cell in your model that Batch Runner should drive — type =, click the cell, press Enter. That is the whole setup. Nothing inside your model is edited or rebuilt.
| Input 1 | ='Model'!$C$5 |
| Input 2 | ='Model'!$C$8 |
| Input 3 | ='Model'!$C$12 |
Link the results you want captured. Every link is checked before anything runs.
The same way, link to the results you care about — IRR, margin, headroom, whatever your model produces. Every link is checked before anything runs, and a broken one is flagged with the reason rather than silently ignored.
| Output 1 | ='Model'!$B$41 | YES |
| Output 2 | ='Model'!$B$42 | YES |
| Output 3 | ='Mdel'!$B$43 | NO — sheet |
One row per case. Fill only what changes; blank cells keep your model's own values.
One row per case, as many as you like. Fill in only the inputs that change from one scenario to the next — anything you leave blank simply keeps whatever your model already has.
| Input 1 | Input 2 | Input 3 |
| 27 000 | 5.2% | 4.5% |

| 31 000 | 5.2% | 4.0% |
Either read the outputs, or let Goal Seek solve each row to its own target.
Two options, and Goal Seek is entirely optional. Read the outputs. The model calculates on your inputs and the results are recorded. This is the normal mode.
Or solve for a target. Turn Goal Seek on, nominate one output as the target and one input as the variable to move, and give each scenario its own goal. Batch Runner works out what that input has to be, then records the outputs as usual.

Results land beside the inputs that produced them, ready to sort and chart.
Batch Runner works through the scenarios in turn, telling you which one it is on. Results land beside the inputs that produced them, so the finished block sorts, filters and charts like any other range. When the run ends, your model's original inputs are put back.

Most tools now bill monthly for work you do occasionally. A tool you use twice a quarter should not appear on your card twelve times a year.

Yours from the moment you download it. Keep using it in ten years, on any machine you own.
Nothing here is a suite. Every tool does one job that people currently do by hand, over and over, and get wrong under time pressure. Buy only the one you need.

Run your model across hundreds of input scenarios in one press, and collect every output beside the inputs that produced it — including a Goal Seek solve on every row.
Spreadsheets · documents · contracts. Each one removes a different repetitive afternoon. Currently on the bench:
Tell me which and it moves up the queue →Two files, and the first one already shows you the tool running on a real model. Most people are running their own model within twenty minutes.
Yes. One payment, and the tool is yours on any machine you own, for as long as you keep the file. There is no subscription, no licence to renew and no account that can expire. If a future version is a genuinely new product, it will be priced as one — and the version you bought will keep working regardless.
Batch Runner attaches to any model by pointing at cells you choose — you link inputs and outputs with ordinary formulas, so nothing inside your model has to change. It does not care how your model is built, only which cells you want driven and which you want read. If you are unsure it fits your file, email hello@heurekatools.com before buying and you will get an honest answer.
No. Batch Runner runs inside Excel on your own machine, on your own data. Nothing is uploaded, nothing is sent anywhere, and there is no account to create.
Batch Runner needs desktop Excel on Windows (2016 or newer) and the file must stay macro-enabled (.xlsm). It is not supported on Excel for Mac, Excel on the web, or the mobile apps. If you work on a Mac, do not buy it yet — a version for Google Sheets is in build.
Email hello@heurekatools.com and describe what you are seeing. Questions come to the person who built the tool, so you get a real answer rather than a template — and if something turns out to be a genuine bug, it tends to end up fixed in the next version.
Yes. A single purchase covers one person, including commercial and client work. If several people at your company need it, there is a team licence — just get in touch.
You already build the model. You just need to see it under two hundred sets of assumptions before Thursday.
The template is agreed. What remains is producing ninety versions of it without a single wrong name or date.
You need the answer, the sensitivity around it, and the paper trail — today, not after a procurement cycle.
