About this gig

I convert Excel spreadsheets into clean online calculators that are easier to use, easier to share, and much better for customers or internal teams.


Instead of sending people a spreadsheet with hidden formulas and confusing tabs, you get a simple web-based tool that presents the same logic in a clear, professional way. This can help you improve user experience, explain pricing faster, reduce manual work, and turn more visitors into leads.


The final calculator can be embedded on your website and adapted to your business flow.


Basic

For simple spreadsheet conversions with basic logic and limited customization. Best for straightforward calculators with a smaller number of inputs.


Standard

For more advanced projects. Includes more complex logic, charts, and better visual matching to your website. Full automation is not included, but I can add one email notification after form submission.


Advanced

For businesses that need automation. Includes advanced logic, stronger customization, and up to 3 automation actions such as saving leads, sending emails, or triggering a webhook.


More complex workflows are available as a custom extra.

I create ROI calculators, pricing tools, product configurators, and lead forms tailored to your business goals. Clean code, fast performance, easy integration, and focus on measurable results. My apps don’t just show results — they focus on business automation with lead collection, email notifications, and custom integrations.
