需要将表格导出为text格式放到项目resources/text文件夹下
新建场景，挂载到Canvas上运行

表格文件格式：

保存格式选text

tableToJson :

import CryptoJS = require('./FileSaver');

const { ccclass, property } = cc._decorator;

@ccclass
export default class tableToJson extends cc.Component {
    protected start(): void {
        this.loadRes("text", (data) => {
            cc.log(data)
            data.forEach(element => {
                cc.log(element.text)
                this.readData(element.text, element._name)
            });
        })
    }

    readData(text, name) {
        let json = {}
        let arr = text.split("\n")
        let head = arr.shift().split("\r")[0].split("\t")
        let type = arr.shift().split("\r")[0].split("\t")
        arr.forEach(element => {
            let jsonArr = element.split("\r")[0].split("\t")
            if (!jsonArr) return;
            for (let i = 0; i < head.length; i++) {
                let headName = head[i];
                if (!jsonArr[i]) {
                    continue;
                }
                let data = jsonArr[i]
                if (!json[jsonArr[0]]) {
                    json[jsonArr[0]] = {}
                }
                if (type[i] == 'int') {
                    json[jsonArr[0]][headName] = Number(data)
                }
                else {
                    json[jsonArr[0]][headName] = data + ""
                }
            }
        });
        cc.log(json)
        this.downloadFile(JSON.stringify(json), name + ".json");
    }

    //保存
    downloadFile(content, filename) {
        //content 为写入文件的内容，可以通过获取文本框的value写入
        var file = new File([content], filename, { type: "text/plain;" });  //type: "text/plain;charset=utf-8"
        CryptoJS.saveAs(file);
    }


    //加载resources下文件
    loadRes(url, completeCallback) {
        if (!url) {
            console.error("url为空！！");
            return;
        }
        let extname = cc.path.extname(url);
        if (extname) {
            // strip extname
            url = url.slice(0, - extname.length);
        }
        cc.resources.loadDir(url, cc.Asset, null, (err, asset: cc.Asset[]) => {
            if (err) {
                console.error("加载失败", url, "\n", err);
                Editor.log("加载失败", url, err);
                return;
            }
            completeCallback(asset);
        });
    }
