    Hi @sweetu ve
    I will recommend you to use PnP library to reach your requirement. Here is the code for you to refer

    import * as React from 'react';    
    import styles from './ExportToExcel.module.scss';    
    import { IExportToExcelProps } from './IExportToExcelProps';    
    import { escape } from '@microsoft/sp-lodash-subset';    
    import { sp } from "@pnp/sp";    
    import "@pnp/sp/webs";      
    import "@pnp/sp/lists";      
    import "@pnp/sp/items";     
    import * as XLSX from 'xlsx';    
    import {saveAs}  from 'file-saver';    
        
    export interface MYListProperties {        
      Title: string;      
      City :String;      
            
    }        
    interface IPnpstate {          
      MyListData:MYListProperties[];        
    }     
    const fileType = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=UTF-8';    
    const fileExtension = '.xlsx';    
    var Heading = [  ["Title","City"],];    
    const saveExcel = (ListData) => {    
      if(ListData.length>0)    
      {    
      const ws = XLSX.utils.book_new();    
       // const ws = XLSX.utils.json_to_sheet(csvData,{header:["A","B","C","D","E","F","G"], skipHeader:false});    
       XLSX.utils.sheet_add_aoa(ws, Heading);    
       XLSX.utils.sheet_add_json(ws, ListData, { origin: 'A2', skipHeader: true });           
        const wb = { Sheets: { 'data': ws }, SheetNames: ['data'] };    
        const excelBuffer = XLSX.write(wb, { bookType: 'xlsx', type: 'array' });    
        const data = new Blob([excelBuffer], {type: fileType});    
        saveAs(data, 'Data' + fileExtension);    
      }    
    }    
        
        
    export default class ExportToExcel extends React.Component<IExportToExcelProps, {}> {    
      constructor(props: IExportToExcelProps, state: IPnpstate) {        
        super(props);        
        this.state = {        
          MyListData: []       
        };      
        this.Listdata=this.Listdata.bind(this);      
      }      
        public componentDidMount(){        
              
        }      
      private  Listdata=async ()=>{      
        //const items: MYListProperties[] = await sp.web.lists.getByTitle("ExportToExcelList").items.get();      
       // return items;      
        //console.log(items);      
        const items: MYListProperties[] = await sp.web.lists.getByTitle("ExportToExcelList").items.get().then((response: MYListProperties[]) => {      
        let result: MYListProperties[] = [];      
          //alert(response.length);    
          response.forEach(element => {      
            result.push({      
           Title: element.Title, City: element.City      
            });      
            });     
                
           // this.setState({ MyListData: result });    
            //alert(result.length);    
            saveExcel(result);    
            return items;      
          });     
                  
               
          
      }    
      public render(): React.ReactElement<IExportToExcelProps> {    
        return (    
          <div >      
            <button type='button' onClick={this.Listdata}>Export to Excel</button>            
              
          </div>      
        );    
      }    
    }
