Convert DataFrame to Excel and write to file path

You can write a DataFrame or Series in Excel format using the toExcel function and specifying the file path.

const dfd = require("danfojs-node")

let data = {
    Abs: [20.2, 30, 47.3],
    Count: [34, 4, 5],
    "country code": ["NG", "FR", "GH"],

let df = new dfd.DataFrame(data);

dfd.toExcel(df, { filePath: "testOut.xlsx"});

Convert DataFrame to Excel and download the file in Client-side lib

You can automatically convert and download an Excel file in a browser environment, by specifying a filename. This will open a download window.

let data = {
    Abs: [20.2, 30, 47.3],
    Count: [34, 4, 5],
    "country code": ["NG", "FR", "GH"],

let df = new DataFrame(data);

dfd.toExcel(df, { fileName: "testOut.xlsx"});
