I will convert your excel calculator into an online web calculator
Felix ZHU
About this gig
Your Excel calculator works in Excel. On your website, it does not.
Most "Excel to web" tools convert the spreadsheet visually - it looks like
a table but does not calculate. I build the calculation itself, in
JavaScript, so the numbers are always right.
What you get
- One self-contained HTML page: your inputs, your formulas, your results
- Runs in the browser, no server, no database, and no monthly subscription
- Mobile responsive, in your brand colours, with your logo
- Embed code for WordPress, Wix, Squarespace, Shopify or a plain page
- A handover note listing every formula I converted
What I need
- Your Excel file, or a screenshot of the formula view
- Which cells the visitor can change
- Special rules: tax, currency, rounding, tiered pricing
Not included: VBA macros (ask first, some can be rebuilt), logins,
accounts, payment processing.
I have built 20+ browser calculators and 7 live sites, all static HTML and
JavaScript. Send your file and I will confirm the price and delivery date today.

I build small, fast web calculators and tools. Over the past year I have shipped 20+ browser-based calculators and 7 live websites: SaaS metrics, pricing, unit economics, fee calculators, and privacy-first PDF tools. Everything is plain HTML and JavaScript, no backend, no plugins, no monthly server bill.
If you have an Excel sheet that people need to use on a website, I turn it into a clean single-page calculator that runs in the browser, works on mobile, and can be embedded anywhere. Fixed price, fixed scope, usually delivered in 2-3 days.
FAQ
My spreadsheet has VBA macros. Can you convert it?
Sometimes. Simple macros that just calculate or format can be rebuilt as JavaScript. Macros that connect to other files, send email, or read external data cannot. Send it and I will tell you honestly before you order.
Can I update the numbers and prices myself later?
Yes. All rates and thresholds sit in one config block at the top of the file. I show you which lines to edit. No coding needed.
Is there a monthly fee?
No. It is a static page. You host it, you own it. Nothing recurring from me.
What if the result does not match my spreadsheet?
Send me the same inputs and the numbers you expect. I fix it. If I cannot match it, you get a refund.
Will it work on my WordPress / Wix / Squarespace site?
Yes. You get the full HTML file plus an iframe embed snippet. If your platform blocks custom code on some plans, tell me first and I will give you the alternative.
