如何将excel文件中的数据集列放入数字数组

import numpy as np

data = np.loadtxt('path/to/file.txt')

import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        List<Double> dataList = new ArrayList<>();

        try {
            File file = new File("path/to/file.txt");
            Scanner scanner = new Scanner(file);

            while (scanner.hasNextDouble()) {
                double number = scanner.nextDouble();
                dataList.add(number);
            }

            scanner.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

        double[] data = new double[dataList.size()];
        for (int i = 0; i < dataList.size(); i++) {
            data[i] = dataList.get(i);
        }
    }
}

using System;
using System.Collections.Generic;
using System.IO;

class Program
{
    static void Main()
    {
        List<double> dataList = new List<double>();

        try
        {
            string[] lines = File.ReadAllLines("path/to/file.txt");

            foreach (string line in lines)
            {
                if (double.TryParse(line, out double number))
                {
                    dataList.Add(number);
                }
            }
        }
        catch (FileNotFoundException e)
        {

        double[] data = dataList.ToArray();
