My article just published on @baeldung — a deep dive into JSON, TOON, and Java format libraries.

TOON uses ~40-50% fewer tokens than JSON. No braces, no brackets, no commas. Ideal for LLM apps where every token costs money.

json-io supports all three formats: JSON, JSON5, and TOON.

@glaforge Guillaume, thank you for creating such a fantastic graphic!

I would like to include it in the json-io https://t.co/ARM4TDbBW1 for display on GitHub. Is the original a vector (SVG) that you could share? Looking for editable version #'s.

First Java JSON library with full TOON read/write support 🎉

TOON is designed for LLM efficiency - 40-50% fewer tokens than JSON.

String toon = JsonIo.toToon(data, null);
MyClass obj = JsonIo.fromToon(toon, null).asClass(MyClass.class);

Useful for @springai and @langaborrego users optimizing token costs.

@starbuxman Thought this might be relevant for This Week in Spring - json-io now has full TOON read/write support for Java.

TOON reduces tokens by 40-50% vs JSON, useful for Spring AI apps. There's an open issue (#4869) requesting native support.

@FinancialPhys Wow. Simply, wow. I wonder how many women today feel the same as this woman?

@DisrespectedThe Here is an image that illustrates what this man is saying. JFK democrats are Republicans now. The modern democrate is a socialist-communist.
