# EnterPurpose Config Converter — Full Reference

> Free online configuration file converter supporting 7 formats and 42 conversion paths. 100% browser-based processing for complete security.

## Overview

EnterPurpose Config Converter (https://enterpurpose.com/tools/) is a free, browser-based tool that converts configuration files between Properties, YAML, JSON, INI, TOML, ENV, and XML formats. It runs entirely client-side — no data is ever sent to a server. Built for developers, DevOps engineers, and system administrators who need to migrate or transform configuration files between different frameworks and platforms.

## Format Details

### Properties (.properties)
Java Properties files use flat key-value pairs with dot notation for hierarchy (e.g., `server.port=8080`). Standard in Spring Boot, Maven, Gradle, and Java enterprise applications. Supports `#` comments and Unicode escape sequences.

### YAML (.yml, .yaml)
Human-readable data serialization using indentation for hierarchy. Standard for Kubernetes manifests, Docker Compose files, Ansible playbooks, GitHub Actions workflows, and CI/CD pipelines. Supports comments, multi-line strings, anchors/aliases, and native data types.

### JSON (.json)
Lightweight data interchange format with strict syntax (double quotes required). Used by REST APIs, npm package.json, VS Code settings, ESLint configs, and web applications. Supports nested objects, arrays, and native types (string, number, boolean, null). No comment support.

### INI (.ini, .cfg)
Simple configuration format using [sections] with key=value pairs. Common in Windows applications, PHP (php.ini), MySQL (my.cnf), and legacy systems. Supports `;` and `#` comments. No native nesting or type system.

### TOML (.toml)
Configuration format designed for clarity. Used by Rust (Cargo.toml), Python (pyproject.toml), Hugo, and Deno. Supports typed values, native datetime, tables, arrays of tables, and inline tables. More expressive than INI while more readable than JSON.

### ENV (.env)
Environment variable files with KEY=VALUE pairs, one per line. Conventionally uses UPPER_SNAKE_CASE keys. Essential for Docker containers, cloud platform deployments (AWS, GCP, Azure), CI/CD secrets, and 12-factor app configuration. No nesting support.

### XML (.xml)
Markup language for structured data with tags, attributes, and namespaces. Used in Maven pom.xml, SOAP web services, .NET configuration, Ant build files, and enterprise applications. Supports schema validation and CDATA sections.
