The Problem
As a developer, I often needed quick tools to inspect or convert JSON, XML, or Base64-encoded data. But most online tools had bloated interfaces, annoying ads, and required uploading files to third-party servers. That’s not always ideal — especially when working with sensitive information or debugging internal formats.
The Solution
I built JSONXMLKit — a set of fast, privacy-respecting tools that run entirely in your browser.
You can:
- 🧾 Format JSON or XML with syntax highlighting and indentation
- 🔍 Search and extract paths using JSONPath or XPath
- 🧬 Encode or decode files to/from Base64, supporting images, PDFs, text files, and more
All tools are client-side — no data is uploaded or logged.
Use Cases
- Quickly debug a nested JSON response without installing anything
- Extract a specific XML tag using XPath
- Decode a Base64 string to verify payloads in JWTs or other APIs
- Format large JSONs from APIs and extract values for QA or analytics
Who It’s For
- Developers & frontend engineers
- QA testers & technical analysts
- Students or educators working with structured data
Why Build Another Tool?
Because dev tools should be:
- Fast ✅
- Free ✅
- Focused ✅
- Privacy-friendly ✅
The goal isn’t to replace complex desktop tools, but to make everyday dev workflows faster — in one tab, with no signups.
