st.json

Display an object or string as a pretty-printed, interactive JSON string.

Function signature[source]

st.json(body, *, expanded=True)

Parameters

body (object or str)

The object to print as JSON. All referenced objects should be serializable to JSON as well. If object is a string, we assume it contains serialized JSON.

expanded (bool or int)

The initial expansion state of the JSON element. This can be one of the following:

  • True (default): The element is fully expanded.
  • False: The element is fully collapsed.
  • An integer: The element is expanded to the depth specified. The integer must be non-negative. expanded=0 is equivalent to expanded=False.

Regardless of the initial expansion state, users can collapse or expand any key-value pair to show or hide any part of the object.

Example

import streamlit as st

st.json(
    {
        "foo": "bar",
        "stuff": [
            "stuff 1",
            "stuff 2",
            "stuff 3",
        ],
        "level1": {"level2": {"level3": {"a": "b"}}},
    },
    expanded=2,
)
