Here are some of the things you can do.

Whatever you already calculate in a spreadsheet, you can ship as a form.

Same form. Your brand.

Say "match my website" and ChatGPT restyles the whole form: colors, fonts, spacing, depth. No design work, no code, and you can undo it anytime.

FontsColorsSpacingDepthField styleDark modeAccent barButton text

Every style option is checked by us, so your form can look like your site and can never break. Try it: build your form and add “brand it like my website.”

The form does the math. You get the answer.

When a customer submits, you don't get raw inputs to plug into your spreadsheet. You get the calculated result — subtotal, tax, total, payback, monthly payment, whatever your formulas compute — already done. Stop running the spreadsheet on every lead.

You decide what they see

By default, every calculation stays private: only you see it. Choose which calculations the customer sees as they fill the form in.

Show them the total, monthly payment, or payback. Keep your margin, cost basis, and broker commission private. One toggle per field.

Bonus: when customers see the answer they're calculating, they convert at ~17× the rate of static contact forms (47.3% vs 2.8%, per Outgrow's 2025 benchmark of 50,000+ forms).

Add it to ChatGPT, then ask for your form.

No drag-and-drop builder. No code. No second tool to learn.

1

Add CalcForms to ChatGPT

One click on the CalcForms app page, then sign in with your email (we send a 6-digit code). A free ChatGPT account works.

2

Ask for your form

Paste your spreadsheet, or just say "build me a quote calculator." ChatGPT builds the form and gives you a link.

3

Share it, change it by asking

Send the link to customers. They fill it in and see their number. Every reply lands in your dashboard with the math done. Want a change? Just ask: "make the discount 15%." Same link.

Create it. Send it. Adjust it. Get the data.

Here is exactly what you can do with CalcForms. No developer needed for any of it.

Your spreadsheet math, exactly

Every formula in your sheet works the same way in the form.

📊

Price tables and rate cards

Your pricing grid comes along, so the form looks up the right rate on its own.

Add as many items as they want

Rooms, products, properties: customers add rows and the form adds them up.

iCalcForms runs inside ChatGPT (a free ChatGPT account works) and inside Claude. You build and edit forms by chatting; your customers just get a link.

Your spreadsheet stays yours.

CalcForms is an official ChatGPT app, and works in Claude too. Your spreadsheet stays in your own ChatGPT or Claude account; we only receive the finished form. Customer replies land in your CalcForms dashboard, and you can download them to Excel anytime. We don't sell your data. We don't train AI on it.

🔁 Cancel anytime 🔒 Your data is yours 💬 Real human support

Real answers.

Does it work in ChatGPT or Claude?
Yes, both. In ChatGPT it is one click on the CalcForms app page, and a free ChatGPT account works. In Claude you add it once from the Connectors page (steps above). Same forms, same dashboard either way.
What kinds of spreadsheets work?
Excel and Google Sheets. We handle the formulas you actually use: IF, VLOOKUP, INDEX/MATCH, PMT, lookup tables, nested logic, percentages, date math. Paste the file into ChatGPT and ask for the form.
Where do submissions go?
Into your CalcForms dashboard. Every answer your customer typed, every calculation, and their email. You decide which calculations the customer sees; the rest stay private to you. Download everything to Excel or CSV anytime.
Can I cancel any time?
Yes — Pro is month-to-month. Cancel any time from your dashboard and you simply stop being billed the next month. You only ever pay for the current month.
Can someone build this for me?
Yes. Start with a free 30-minute onboarding call: we look at your spreadsheet together and build the form with you. If you would rather hand the whole thing off, the Done-for-you plan (from $499 one-time, includes 3 months of Pro) means we build it, test it against your past quotes, and hand you the live link.
