Java properties to JSON converter

How to use it

1. Enter properties text, build nested objects from dots, turn numbers and true/false into typed values and indentation.
2. The result appears straight away and updates as you edit.
3. Copy the result, or copy a link that keeps the same values to share it.

How it is calculated

Lines starting with # or ! are comments, and a line ending in an odd number of \ continues on the next. The key ends at an unescaped =, : or space, and \t, \n and \uXXXX are decoded. With nesting, a.b.c becomes nested objects and list[0] a list; with typing, text becomes a number only if its form stays the same.

Example

Inputs: Build nested objects from dots = yes, Turn numbers and true/false into typed values = yes, Indentation = 2 spaces. Result: JSON: { "server": { "port": 8080 }, "spring": { "application": { "name": "demo" }, "datasource": { "url": "jdbc:mysql://localhost:3306/shop" } }, "app": { "languages": [ "ar", "en" ], "title": "ToolSahla" } }; Keys: 6.

# Spring Boot
server.port=8080
spring.application.name=demo
spring.datasource.url=jdbc:mysql://localhost:3306/shop
app.languages[0]=ar
app.languages[1]=en
app.title=ToolSahla

{
  "server": {
    "port": 8080
  },
  "spring": {
    "application": {
      "name": "demo"
    },
    "datasource": {
      "url": "jdbc:mysql://localhost:3306/shop"
    }
  },
  "app": {
    "languages": [
      "ar",
      "en"
    ],
    "title": "ToolSahla"
  }
}

Limits and caveats

• Nesting rejects a key that is both a value and a group, such as a and a.b; turn the option off in that case.
• For a repeated key the last value wins, as in Java.
