YAML to properties converter

How to use it

1. Enter yaml text, list item style and escape non-ascii as \uxxxx.
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

YAML is read with the YAML 1.2 core schema, then each value's path is joined with dots such as spring.datasource.url, and list items use [0] brackets or dots. Spaces, = and : are escaped in keys, line breaks as \n in values, and non-ASCII letters can become \uXXXX.

Example

Inputs: List item style = Brackets list[0] (Spring), Escape non-ASCII as \uXXXX = no. Result: .properties: server.port=8080 spring.application.name=demo spring.datasource.url=jdbc:mysql://localhost:3306/shop spring.datasource.username=root app.languages[0]=ar app.languages[1]=en ; Keys: 6.

server:
  port: 8080
spring:
  application:
    name: demo
  datasource:
    url: jdbc:mysql://localhost:3306/shop
    username: root
app:
  languages:
    - ar
    - en

server.port=8080
spring.application.name=demo
spring.datasource.url=jdbc:mysql://localhost:3306/shop
spring.datasource.username=root
app.languages[0]=ar
app.languages[1]=en

Limits and caveats

• The tool supports a clear YAML subset: maps, lists, scalars, quoted strings, | and > block scalars and [ ] and { } flow collections. Anchors &, aliases *, tags ! and multiple documents are rejected with a clear message.
• Empty maps and lists are not written, and comments are dropped.
