About Us

Fast, free, and privacy-first online tools.

Our Mission

At ToolsFusion, our mission is simple: To provide creators, developers, freelancers, and business owners with fast, high-precision online tools that respect user privacy and eliminate web clutter.

We believe daily utilities — whether calculating credit card processing fees or converting JSON data to Excel — should be fast, reliable, and completely free of annoying paywalls, forced sign-ups, or excessive advertisements.

What We Build

ToolsFusion combines financial tools and developer utilities into one streamlined platform:

📊 Financial & E-Commerce Calculators

  • Payment Gateway Fee Estimators: Calculate exact domestic and international transaction fees for processors like Stripe and PayPal.
  • Profitability & Pricing Tools: Instantly determine gross margins, markup percentages, and required selling prices to protect your business bottom line.

🛠️ Developer & Data Utilities

  • Data Converters: Bidirectional transformation between JSON arrays, CSV spreadsheets, and Excel .xlsx workbooks.
  • String & Text Utilities: Live case converters (camelCase, snake_case, kebab-case, Title Case) and word counters.

Our Core Principles
