dcc.Clipboard

The dcc.Clipboard component copies text to the
browser’s clipboard by clicking on a copy icon.

Simple Clipboard Example

The easiest way to trigger the copy is by using the target_id property.
No callback is required! Place dcc.Clipboard in the layout where
you would like the copy icon located. Specify the target_id of the component
with text to copy. In this example, the content of the value property of the
dcc.Textarea is copied to the clipboard.

from dash import Dash, dcc, html

app = Dash(__name__)

app.layout = html.Div([
    dcc.Textarea(
        id="textarea_id",
        value="Copy and paste here",
        style={"height": 100},
    ),
    dcc.Clipboard(
        target_id="textarea_id",
        title="copy",
        style={
            "display": "inline-block",
            "fontSize": 20,
            "verticalAlign": "top",
        },
    ),
])

if __name__ == "__main__":
    app.run_server(debug=True)

Clipboard icon inside a scrollable div

The style and className can be used to change the design or the position
of the copy icon. This example shows the icon placed in the top right corner
of a scrollable div. The next example shows the icon styled like a button.

from dash import Dash, dcc, html

app = Dash(__name__)

code = """```
html.Div([
    dcc.Markdown(
        code,
        id="code",
        style={"width": 500, "height": 200, "overflow": "auto"},
    ),
    dcc.Clipboard(
        target_id="code",
        style={
            "position": "absolute",
            "top": 0,
            "right": 20,
            "fontSize": 20,
        },
    ),
], style={"width": 500, "height": 200, "position": "relative"})
```"""

app.layout = html.Div([
    dcc.Markdown(
        code,
        id="code",
        style={"width": 500, "height": 200, "overflow": "auto"},
    ),
    dcc.Clipboard(
        target_id="code",
        style={
            "position": "absolute",
            "top": 0,
            "right": 20,
            "fontSize": 20,
        },
    ),
], style={"width": 500, "height": 200, "position": "relative"})


if __name__ == "__main__":
    app.run_server(debug=True)
html.Div([
    dcc.Markdown(
        code,
        id="code",
        style={"width": 500, "height": 200, "overflow": "auto"},
    ),
    dcc.Clipboard(
        target_id="code",
        style={
            "position": "absolute",
            "top": 0,
            "right": 20,
            "fontSize": 20,
        },
    ),
], style={"width": 500, "height": 200, "position": "relative"})

Updating the Clipboard Text in a callback

When target_id is not specified, the content of the text property
is copied to the clipboard. This works well with components like the DataTable
where you may want to customize the text in a callback. In this example,
the dataframe is converted to text with pandas to_csv(). See the
pandas documentation
for other formatting options such as including or excluding headers.

from dash import Dash, dcc, html, Input, Output, State, dash_table
import pandas as pd

app = Dash(__name__)

df = pd.read_csv("https://raw.githubusercontent.com/plotly/datasets/master/solar.csv")

app.layout = html.Div(
    [
        dcc.Clipboard(id="table_copy", style={"fontSize":20}),
        dash_table.DataTable(
            df.to_dict("records"),
            [{"name": i, "id": i} for i in df.columns],
            id="table_cb",

        )
    ]
)


@app.callback(
    Output("table_copy", "content"),
    Input("table_copy", "n_clicks"),
    State("table_cb", "data"),
)
def custom_copy(_, data):
    dff = pd.DataFrame(data)
    # See options for .to_csv() or .to_excel() or .to_string() in the  pandas documentation
    return dff.to_csv(index=False)  # includes headers

if __name__ == "__main__":
    app.run_server(debug=True)

Limitations

This component uses the Clipboard API,
which is not supported by older browsers like Internet Explorer and is
unfortunately disabled frequently by corporate IT policies. When the Clipboard
API is unavailable, the icon will not appear in the app and a warning message is
written to the console.

Currently dcc.Clipboard only supports copying text to the
clipboard. It does not support paste or other clipboard operations.
