What is a Google Sheets Tool?
A Google Sheets tool is a spreadsheet built as a product: a calculator, planner or template that does one job for a specific person. The buyer types a few numbers into marked cells and gets an answer, a plan or a ready-to-send document. Freelancers use them to price jobs, small shops to plan stock, couples to split wedding budgets.
As a first product it has a big advantage: it is the cheapest piece of real software you can ship. If people copy it, use it every week and ask for more, you have proof that the logic is worth turning into an app. And if they pay €9 for the sheet, you also have your first revenue before writing any code.
When should you use it?
Use it when:
- Your customers already do the job in a messy spreadsheet, on paper or in their head. Contextual inquiry is a great way to spot this: watch for the sheet they keep open all day.
- The value sits in a calculation, a structure or a checklist, and does not depend on other users joining.
- Your audience is comfortable with spreadsheets: freelancers, small business owners, finance people, teachers, event planners.
Skip it when the product needs live data from other users, notifications, or works mainly on a phone. Spreadsheets on a small screen frustrate people, so an audience that lives on mobile will judge the format and never get to your logic.
How do you do it, step by step?
-
Find a repeated calculation people hate. Search Google, Etsy and Reddit for “[job] spreadsheet template”, “[job] calculator” and “how do I price [task]”. If people sell or beg for templates in your niche, demand exists. Write the promise: “Type in 5 numbers, get a price you can send to the client.”
-
Split the sheet into three tabs. Start here with instructions in four lines. Inputs where every cell the user may change is light yellow. Results with the answer in big type. Put the formulas in a fourth tab called Workings and hide it (right-click the tab, Hide sheet). Five yellow cells feel friendly, while a wall of 200 formulas makes buyers feel lost.
-
Stop bad inputs with drop-downs. Select an input cell, open Data > Data validation and allow only a list (“Weekly, Every 2 weeks, Monthly”) or a number range. A typical “your sheet is broken” email comes from someone typing “approx 3” into a number cell.
-
Protect the formulas. Open Data > Protect sheets and ranges, add the Workings and Results tabs and choose either “Show a warning when editing this range” or restrict editing to yourself. Google’s own help on protecting sheets and ranges is clear that this is not a security measure, since people can still copy the file. Treat it as a guard against accidents.
-
Test it with 3 people and their real numbers. Sit with each person (or share screens) and say only: “Use this to price your next job.” Note every question they ask. Each question is a missing label or instruction. Fix, then test with 3 more.
-
Share it as a copy link. Set sharing to “Anyone with the link” as Viewer, copy the link and change the ending from
/editto/copy. Anyone who opens it sees a “Make a copy” button and gets their own version, so your master stays clean. Record a 2-minute Loom walkthrough and put the link in the Start here tab. -
Test willingness to pay. Offer a free version (the calculator) in exchange for an email through a Tally form, and a paid version with extras (say, a ready-to-send quote and a client log) on Gumroad or Etsy. Price it between €7 and €29, our rule of thumb for a first template. Deliver the copy link in the purchase confirmation.
What does a worked example look like?
Say Rosa wants to build software that helps freelance home cleaners price their jobs. Many cleaners guess, undercharge for big houses and lose money on travel. Instead of an app, she builds a Google Sheet.
Inputs: number of bedrooms, bathrooms, frequency (drop-down), pets (yes/no), travel time in minutes and the hourly rate the cleaner wants to earn. Results: a suggested price per visit, the real hourly rate after travel, and a three-line quote the cleaner can paste into WhatsApp.
She tests it with 6 cleaners. Four ask the same question: “Where do I put cleaning products?” She adds a supplies cost field. Then she shares the free version in two cleaner Facebook groups behind a Tally email form. In 3 weeks, 260 cleaners request the sheet. She emails them a €12 “Pro” version with a monthly income tracker and a client list, and 23 buy it on Gumroad. That is €276, a list of 260 cleaners and a clear signal: the pricing logic is worth turning into a simple app later.
Which free tools help?
| Tool | What you use it for | Free plan |
|---|---|---|
| Google Sheets | Building, protecting and sharing the tool | Free with a Google account |
| Tally | Email form that delivers the free copy link | Yes, unlimited forms and submissions |
| Gumroad | Selling the paid version as a digital product | No monthly fee, a fee per sale |
| Etsy | Reaching buyers who already search for templates | Listing and sales fees apply |
| Loom | A 2-minute walkthrough video in the Start here tab | Yes, short recordings |
What mistakes should you avoid?
- Showing every formula. A wall of numbers makes buyers feel the tool is for experts. Hide the workings, show the answer.
- No instructions. If the first screen does not say where to type, people email you or give up.
- Sharing the edit link. One buyer deletes a formula and every other user’s tool breaks. Always share a copy link.
- Building for every case. A tool for “all freelancers” ends up with 40 inputs. Pick one job for one person and let the second version grow from requests.
- Giving everything away for free. Keep a clear paid upgrade from day one so you test willingness to pay alongside interest.
How do you know it worked?
Our rule of thumb for a go: at least 100 people request the free version in a month, 5% or more of them buy the paid version, and several buyers ask for a feature you had not planned. Also check use: ask 10 users whether they used it again in the last week. Repeat use is what turns a template into a product.
No-go: lots of downloads, hardly any sales and nobody using it twice. The topic is interesting but the tool does not save enough time. Revisit the problem before building more tabs.
What should you do next?
If the free version brings in emails, use it as a lead magnet or share it as a free tool on your site. To test a higher price or a bundle without a shop, try a payment link test. The F/MS startup game helps you go from a sheet like this to a validated business with an AI co-founder.
FAQ
How do I share a Google Sheet so people get their own copy?
Set sharing to “Anyone with the link” as Viewer, copy the link and replace /edit at the end with /copy. People who open it get a “Make a copy” button, and your original stays untouched.
Can I stop people from seeing my formulas in Google Sheets?
Partly. You can hide the tab with formulas and protect the ranges, which stops accidental edits. A determined user can still copy the file and look inside, so do not rely on protection to guard a secret method.
Can you sell Google Sheets templates?
Yes. Founders sell them on Gumroad, Etsy and their own sites, and deliver a copy link after purchase. Check each platform’s rules on digital products and fees before you list.
