What it is

Nazamos: the homepage
Nazamos is a suite of developer utilities designed for maximum privacy and speed. All tools execute entirely within your browser with no data transmission to external servers. The platform includes a JSON formatter and beautifier for cleaning messy JSON structures, a JSON validator for detecting syntax errors with precise line markers, and an interactive tree viewer for exploring complex JSON payloads. It offers conversion tools to generate TypeScript interfaces, Rust Serde structs, and Zod schemas directly from JSON. Additional utilities include XML formatting, JSON minification, JWT decoding, JSON diffing, and support for CSV and YAML conversions. The service operates completely offline after initial load and is designed for air-gapped environments and secure API development workflows.

Quick answers
Is my JSON data secure when using Nazamos?
Yes, 100%. Nazamos runs completely client-side in your web browser. None of your JSON payloads, API responses, or sensitive keys are ever uploaded or transmitted to any external server.
Can I convert JSON into TypeScript interfaces directly?
Yes. Simply paste your JSON in the editor and select the TypeScript tab. The tool automatically analyzes the nested structure, handles arrays, and generates recursive TypeScript interfaces with clean types.
How does Nazamos handle invalid JSON syntax?
The real-time parser detects common syntax mistakes such as unquoted keys, trailing commas, or unescaped quotes, instantly displaying the precise line number and error cause.
Does this tool work completely offline?
Yes. Once loaded, Nazamos does not depend on any backend API. You can disconnect your internet connection or use it in air-gapped corporate environments without interruption.
Can I copy the exact JSON path of nested keys?
Yes. Switch to the Tree View tab and hover over any object key or array index to click the copy path button to get paths like users[0].address.city.
