How to Use the Properties to YAML Converter

Unflatten flat dotted property key-value configurations into nested hierarchical YAML in seconds.

Paste Properties Content

Paste flat dotted properties straight into the input editor, or upload a .properties file.

Confirm Hierarchy

Review the keys to make sure they are dot-separated (e.g. app.db.port) to allow nested parsing.

Convert Instantly

The parser runs live as you edit or type, building cleanly nested levels and indentation instantly.

Copy or Download

Copy the generated YAML output to your clipboard, or download it as a .yaml file for your project.

Frequently Asked Questions

Why convert Properties to YAML?
YAML is much more readable for complex configurations. When migrating flat .properties files to .yaml, this tool saves time by automatically building the nested levels.
Does it handle complex keys?
Yes, it handles any number of nested levels. a.b.c.d=value will result in a 4-level deep YAML structure.
Is my data secure?
Absolutely. Like all tools on Upendra.dev, the conversion happens entirely in your browser. No data ever leaves your machine.
Can I use comments in my properties file?
Yes. Single line comments starting with # are preserved during input parsing to help you maintain contextual notes in your config configurations.
Does this tool support lists or arrays?
Currently, properties files representing array elements (e.g., list[0]=value, list[1]=value) are parsed as standard dotted strings. You can easily adjust the resulting YAML indentation manually if list syntax is required.
