The pricing
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.
€19 / month
Access ends when you stop paying. The files you built with it may stop opening properly too.
€39 once
Yours from the moment you download it. Keep using it in ten years, on any machine you own.
Inside the first tool
Excel can change one input and show you one answer. Batch Runner changes any number of inputs, hundreds of times, and lays every answer out beside the assumptions that produced it.
Point at the inputs you want driven and the outputs you want captured, using ordinary Excel formulas. Nothing inside your model changes.
One row per case. Fill only the inputs that change; leave the rest blank and they keep your model's own values.
Every row is calculated in turn, and the results appear beside it. Your model is put back exactly as it was.
Up to 30 inputs and 30 outputs per run, across as many scenario rows as you care to write. What took an afternoon of typing and copying takes one click.
Excel solves one case at a time, by hand. Batch Runner solves every row to its own target — so you get a table of break-even prices, required rents or maximum bids, not a single number.
Data Tables stop at two inputs. Batch Runner takes thirty, in any combination you write, so you can model whole scenarios rather than grid points.
It attaches from outside by linking to cells. No rebuilding, no named ranges to add, no formulas to rewrite. It works with a model you inherited as readily as one you wrote.
Every link is validated first and flagged in plain language — broken reference, missing sheet, external file. You find out before the run, not from a column of odd-looking numbers after it.
Original inputs are captured before the first row and restored after the last — including if an error interrupts the run. Your model is never left holding the final scenario's numbers.
Results land beside their inputs, one row per scenario, so the whole block sorts, filters, charts and pivots like any other range. Goal Seek rows carry their own diagnostics — how many iterations it took and how close it landed — so you know which answers to trust.
The catalogue
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.
What arrives
The download is not a bare file with a hopeful README. Most people are running their own model within twenty minutes.
01
The tool
Ready to run. Drop it into your own file, or work in the one provided.
02
A real manual
Setup, layout, worked examples and a troubleshooting table. Written, not generated.
03
A demo model
A complete worked example you can run in the first minute to see how it behaves.
04
Direct support
Reply to your receipt and it reaches the person who built it. Not a queue.
Who buys these
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.
Before you buy
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.
Get in touch
Ask whether it fits your model, tell me which tool to build next, or report something that broke. Emails come to the person who built the tools, not a helpdesk — expect a reply within a working day.
