How to fix a JSON Text in Minecraft? [duplicate]

Solution 1:

Your syntax is incorrect because to chain multiple json string definitions together, you need to arrange them in an array.

Arrays are defined using the square [] brackets.
A compound bracket; curly {} brackets can only be used for nesting other constants.

In theory, you need to do this:

/tellraw @a [{"text":"(YOU!)","color":"blue","Bold":"true"},{"text":"Rawr.","color":"red","bold":"true"}]  
            ^                                                                                           ^

Might I also add, multiple strings in an array are explictly added, so (without color), your text will look like this:

(YOU!)Rawr.

You may want to add a space into one of the strings to denote seperation.
