Download json, is this possible?


I have an imputo for csv, and whant to download it to json. Is this possible? How?

I pass from a drag n drop a csv, pass it to json, but can’t download it? (or don’t know how).

How can I download it?

Hello @topotaman,

It’s pretty straightforward, use this as an example:

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

app = Dash(__name__)
app.layout = html.Div(
        html.Button("Download JSON", id="btn_json"),

df = pd.DataFrame({"a": [1, 2, 3, 4], "b": [2, 1, 5, 6], "c": ["x", "x", "y", "y"]})

    Output("download-dataframe-json", "data"),
    Input("btn_json", "n_clicks"),
def func(n_clicks):
    return dcc.send_data_frame(df.to_json, "mydf.json")

if __name__ == "__main__":
    app.run_server(debug=True, port=8000)

Basically, pass your dataframe to the dcc.send_data_frame as json. :slight_smile:

thanks! yeeeeeha!!
