Properties to YAML converter

How to use it

1. Enter properties text, 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

The file is read with Java Properties.load rules, then every key is split at dots and [n] becomes a list item, checking that lists run from 0 without gaps. With typing, 8080 becomes a number and true a boolean, while 1.10 stays text because its form would change. YAML is then written with 2 or 4 space indentation.

Example

Inputs: Turn numbers and true/false into typed values = yes, Indentation = 2 spaces. Result: YAML: server: port: 8080 spring: application: name: demo datasource: url: jdbc:mysql://localhost:3306/shop app: languages: - ar - en title: ToolSahla .

# 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

• A key that is both a value and a group, such as a and a.b, cannot be written as YAML.
• Comments are dropped, and for a repeated key the last value wins.
