st.json

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

Function signature[source]

st.json(body, *, expanded=True, width="stretch")

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.

width ("stretch" or int)

The width of the JSON element. This can be one of the following:

  • "stretch" (default): The width of the element matches the width of the parent container.
  • An integer specifying the width in pixels: The element has a fixed width. If the specified width is greater than the width of the parent container, the width of the element matches the width of the parent container.

Example

import streamlit as st

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