📄 Data Format Conversions

JSON Converter

• JSON → Python Dict — Produces valid Python with True/False/None, quoted keys
• JSON → JavaScript Object — Clean JS syntax, template literals for multi-line strings
• JSON → YAML — Human-readable YAML with configurable indentation
• JSON → XML — Well-formed XML from JSON
• JSON → TOML — Rust Cargo.toml, Python pyproject.toml, Hugo config
• JSON → CSV — Excel-ready CSV with headers, proper escaping
• JSON → .env — Environment variable file from JSON config

YAML Converter

• YAML → JSON — Parse Kubernetes, Docker Compose, GitHub Actions config
• XML → YAML — Direct conversion with attribute support

XML Converter

• XML → JSON — Parse RSS feeds, SOAP responses, config files
• XML → YAML — Convert legacy XML to modern YAML config

CSV Converter

• CSV → JSON — Smart type detection (numbers, booleans, nulls auto-parsed)
• JSON → CSV — Export nested data to flat CSV

TOML Converter

• TOML → JSON — Parse Cargo.toml, pyproject.toml, config.toml

.env File Parser

• .env → JSON — Parse environment files, skip comments, handle quotes
• JSON → .env — Generate environment files from JSON config

Data Extraction

• Extract Values — Pull all leaf values from any nested structure
• Extract Keys — Get dot-notation paths (user.address.city) from any JSON/YAML

🔧 String Encoding & Decoding

Base64 Encoder / Decoder

• Base64 Encode — Encode strings, JWT payloads, data URIs
• Base64 Decode — Decode tokens, PEM certificates (multi-line supported)

URL Encoder / Decoder

• URL Encode — RFC 3986 compliant encoding for query strings and paths
• URL Decode — Decode percent-encoded strings from logs or API responses

HTML Entity Encoder / Decoder

• HTML Encode — Escape <, >, &, " for safe rendering
• HTML Decode — Convert &, <, > back to characters (single-pass, no double-decode)

📝 Case Converter

✨ JSON Formatter

• Minify JSON — Strip whitespace for production, API payloads (60-80% size reduction)
• Beautify JSON — Pretty-print with configurable indent (2 or 4 spaces)
• Single Line — Collapse multi-line text to one line
• Multi Line — Expand single-line content to multiple lines

📋 Real-World Examples

Convert JSON to Python Dict

Input:  {"name":"Alice","active":true,"score":null}
Output: {'name': 'Alice', 'active': True, 'score': None}

Convert JSON to YAML (Kubernetes-ready)

# Input JSON:
{"apiVersion":"v1","kind":"Service","metadata":{"name":"my-app"}}

# Output YAML:
apiVersion: v1
kind: Service
metadata:
  name: my-app

Parse .env File to JSON

# Input (.env):         Output (JSON):
DATABASE_URL=postgres   {"DATABASE_URL": "postgres",
API_KEY="my secret"      "API_KEY": "my secret"}
# ignored comment

CSV to JSON Array

# Input:               # Output:
name,age,active        [{"name":"Alice","age":30,"active":true},
Alice,30,true           {"name":"Bob","age":25,"active":false}]
Bob,25,false

Decode Base64 JWT Payload

Input:  eyJ1c2VyIjoiQWxpY2UiLCJyb2xlIjoiYWRtaW4ifQ==
Output: {"user":"Alice","role":"admin"}

⌨️ Keyboard Shortcuts

🔒 Privacy & Security

• Zero network calls — all transformations run entirely on your machine
• No telemetry — your code is never sent anywhere
• No API keys — works fully offline
• Input validation — 1MB size limit, recursion depth limits, YAML schema restrictions
• Open source — fully auditable on GitHub

🆚 Why Not Just Use an Online Converter?

🐛 Troubleshooting

Shortcut not working? Another extension may be using Ctrl+Shift+T. Use the right-click menu or Command Palette instead.

Transformation shows error? Check that your input is valid for the format (e.g. valid JSON, valid XML). The error message will tell you exactly what's wrong.

Context menu not appearing? Make sure text is selected before right-clicking.
