What is JSON to Lua Converter?

Need to generate Lua tables from your JSON (JavaScript Object Notation) data? This tool does that instantly. Perfect for Lua developers working with game development, embedded systems, or scripting who need to deserialize JSON into Lua tables. Generate Lua tables, nested structures, and type definitions automatically.

According to Lua documentation, tables are the primary data structure in Lua and work perfectly for JSON data. Our converter analyzes your JSON structure and generates proper Lua tables. First, validate your JSON using our JSON Validator, then convert it to Lua. You can also format your JSON with our JSON Formatter first if needed.

Everything happens in your browser – your JSON never leaves your computer. Convert, download, and use your Lua code right away.

What Makes This Tool Different

Automatic Table Generation

We analyze your JSON structure and automatically generate Lua tables. JSON objects become Lua tables, arrays become Lua tables with numeric indices, everything gets proper Lua syntax.

Nested Structure Support

Handles deeply nested JSON structures perfectly. Nested objects become nested tables, arrays become tables with sequential indices.

Proper Lua Syntax

Generates valid Lua code with proper table syntax. Uses Lua's native table structure for maximum compatibility.

File Upload Support

Got a big file? Just upload it. Works great for converting those massive JSON configs or data files without copy-pasting.

Download Lua

One click to download your Lua file. Drop it into your Lua project and start using it. Perfect for game development, embedded systems, or scripting.

Clean Code Output

The generated Lua code is clean and well-formatted. Tables are properly structured and follow Lua conventions.

How It Works

1

Paste or Upload JSON

Paste your JSON into the left editor, or click "Upload" to load a file. The JSON should be valid – use our JSON Validator first if you're not sure. You can also click "Sample" to see an example.

2

Configure Options

Set your table name. These settings customize the generated Lua code to match your project's conventions.

3

Download or Copy

Click "Download" to save the Lua file, or "Copy" to copy it to your clipboard. The Lua code is ready to use in your project. Drop it into your Lua project and start using it.

When You'd Actually Use This

Game Development

Generate Lua tables from JSON configs for game engines. Create data structures for JSON-based game configurations, level data, or asset definitions. Perfect for Lua-based game engines.

Embedded Systems

Create Lua tables from JSON data for embedded systems. Generate data models for JSON-based configurations or device settings. Perfect for Lua scripting in embedded applications.

Scripting

Generate Lua code from JSON data structures. Perfect for creating data models, configuration tables, or data definitions from JSON schemas.

Configuration Files

Convert JSON configuration files to Lua tables. Makes configuration management easier in Lua applications and scripts.

Common Questions

Is my JSON data stored?

Nope. Everything happens right in your browser. Your JSON never leaves your computer – we don't even see it.

How are JSON objects handled?

JSON objects become Lua tables. Properties become table keys, and nested objects become nested tables. Arrays become Lua tables with numeric indices starting from 1.

Can I use the generated Lua code?

Yes. The generated Lua code is valid and ready to use. Drop it into your Lua project and start using it. You may want to review and refine the tables for your specific use case.

What Lua version is supported?

The generated code works with Lua 5.1 and later. It uses standard Lua features and follows Lua conventions for maximum compatibility.

Does it work with large JSON files?

Yep. Since everything happens in your browser, it depends on your device. Small to medium JSON structures convert instantly. Really huge structures might take a few seconds.

What about JSON parsing libraries?

The generated Lua code uses native Lua tables. You can use libraries like dkjson or cjson to parse JSON strings into these table structures.
