如何使用javascript将json数据导出到excel文件？

Question

I have json data which needs to be exported to an excel sheet. I have tried

window.open('data:application/vnd.ms-excel,' + encodeURIComponent( $('#tableId').html()));

But this works for html table only.

 $(document).ready(function() { $('button').click(function() { var data = $('#txt').val(); if (data == '') return; JSONToCSVConvertor(data, "Vehicle Report", true); }); }); function JSONToCSVConvertor(JSONData, ReportTitle, ShowLabel) { //If JSONData is not an object then JSON.parse will parse the JSON string in an Object var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData; var CSV = ''; //Set Report title in first row or line CSV += ReportTitle + '\\r\\n\\n'; //This condition will generate the Label/Header if (ShowLabel) { var row = ""; //This loop will extract the label from 1st index of on array for (var index in arrData[0]) { //Now convert each value to string and comma-seprated row += index + ','; } row = row.slice(0, -1); //append Label row with line break CSV += row + '\\r\\n'; } //1st loop is to extract each row for (var i = 0; i < arrData.length; i++) { var row = ""; //2nd loop will extract each column and convert it in string comma-seprated for (var index in arrData[i]) { row += '"' + arrData[i][index] + '",'; } row.slice(0, row.length - 1); //add a line break after each row CSV += row + '\\r\\n'; } if (CSV == '') { alert("Invalid data"); return; } //Generate a file name var fileName = "MyReport_"; //this will remove the blank-spaces from the title and replace it with an underscore fileName += ReportTitle.replace(/ /g, "_"); //Initialize file format you want csv or xls var uri = 'data:text/csv;charset=utf-8,' + escape(CSV); // Now the little tricky part. // you can use either>> window.open(uri); // but this will not work in some browsers // or you will not get the correct file extension //this trick will generate a temp <a /> tag var link = document.createElement("a"); link.href = uri; //set the visibility hidden so it will not effect on your web-layout link.style = "visibility:hidden"; link.download = fileName + ".csv"; //this part will append the anchor tag and remove it after automatic click document.body.appendChild(link); link.click(); document.body.removeChild(link); }

If the csv format fits your need, then it can be easily done like in this topic .

Otherwise, you will have to parse manually your JSON to the 'XML' format of a Excel file (because I don't know any library doing this). In this case, you will have to study the Excel file format, which is explained in this MSDN blog .

Cheers

this solution works fine with large JSON data, IE error issues, hope this will help

 $(document).ready(function() { $("#button1").on('click', function(e) { var url = ""; $.ajax({ type: "GET", url: url, success: function(result) { DownloadJsonData(result, "NewFile", true); }, error: function(result) { alert('Error '); } }); }); function DownloadJsonData(JSONData, FileTitle, ShowLabel) { //If JSONData is not an object then JSON.parse will parse the JSON string in an Object var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData; var CSV = ''; //This condition will generate the Label/Header if (ShowLabel) { var row = ""; //This loop will extract the label from 1st index of on array for (var index in arrData[0]) { //Now convert each value to string and comma-seprated row += index + ','; } row = row.slice(0, -1); //append Label row with line break CSV += row + '\\r\\n'; } //1st loop is to extract each row for (var i = 0; i < arrData.length; i++) { var row = ""; //2nd loop will extract each column and convert it in string comma-seprated for (var index in arrData[i]) { row += '"' + arrData[i][index] + '",'; } row.slice(0, row.length - 1); //add a line break after each row CSV += row + '\\r\\n'; } if (CSV == '') { alert("Invalid data"); return; } //Generate a file name var filename = FileTitle + (new Date()); var blob = new Blob([CSV], { type: 'text/csv;charset=utf-8;' }); if (navigator.msSaveBlob) { // IE 10+ navigator.msSaveBlob(blob, filename); } else { var link = document.createElement("a"); if (link.download !== undefined) { // feature detection // Browsers that support HTML5 download attribute var url = URL.createObjectURL(blob); link.setAttribute("href", url); link.style = "visibility:hidden"; link.download = filename + ".csv"; document.body.appendChild(link); link.click(); document.body.removeChild(link); } } } }) 

 .flex { display: flex; justify-content: center; } .flex-item+.flex-item { margin-left: 10px; } .button { border-radius: 4px; background-color: #f4511e; border: none; color: #FFFFFF; text-align: center; font-size: 28px; padding: 20px; width: 100%; transition: all 0.5s; cursor: pointer; margin: 15px; margin-left: 25px; } .button span { cursor: pointer; display: inline-block; position: relative; transition: 0.5s; } .button span:after { content: '\\00bb'; position: absolute; opacity: 0; top: 0; right: -20px; transition: 0.5s; } .button:hover span { padding-right: 25px; } .button:hover span:after { opacity: 1; right: 0; }

Answer 4

@niravpatel9898's original answer works well for me, however the actual download to CSV causes this error in excel while parsing the JSON data I have: Some features might be lost if you save this workbook in the comma-delimited (.csv) format. To preserve these features, save it in an Excel file format. Is there any way to get rid of this warning and ensure the data parses and downloads to Excel correctly?

When I try using changing the code to output to .xls or when I use the solution suggested by @iwayankit, it does not seem to work. Below is the original code by @niravpatel9898 that I am trying to work with:

<script>
$(document).ready(function() {
  $('button').click(function() {
    var data = $('[id="xyz"]').val();
    if (data == '')
      return;

    JSONToCSVConvertor(data, "Report", true);
  });
});

function JSONToCSVConvertor(JSONData, ReportTitle, ShowLabel) {
  //If JSONData is not an object then JSON.parse will parse the JSON string in an Object
  var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;

  var CSV = '';
  //Set Report title in first row or line

  CSV += ReportTitle + '\r\n\n';

  //This condition will generate the Label/Header
  if (ShowLabel) {
    var row = "";

    //This loop will extract the label from 1st index of on array
    for (var index in arrData[0]) {

      //Now convert each value to string and comma-seprated
      row += index + ',';
    }

    row = row.slice(0, -1);

    //append Label row with line break
    CSV += row + '\r\n';
  }

  //1st loop is to extract each row
  for (var i = 0; i < arrData.length; i++) {
    var row = "";

    //2nd loop will extract each column and convert it in string comma-seprated
    for (var index in arrData[i]) {
      row += '"' + arrData[i][index] + '",';
    }

    row.slice(0, row.length - 1);

    //add a line break after each row
    CSV += row + '\r\n';
  }

  if (CSV == '') {
    alert("Invalid data");
    return;
  }

  //Generate a file name
  var fileName = "";
  //this will remove the blank-spaces from the title and replace it with an underscore
  fileName += ReportTitle.replace(/ /g, "_");

  //Initialize file format you want csv or xls
  var uri = 'data:text/csv;charset=utf-8,' + escape(CSV);

  // Now the little tricky part.
  // you can use either>> window.open(uri);
  // but this will not work in some browsers
  // or you will not get the correct file extension    

  //this trick will generate a temp <a /> tag
  var link = document.createElement("a");
  link.href = uri;

  //set the visibility hidden so it will not effect on your web-layout
  link.style = "visibility:hidden";
  link.download = fileName + ".csv";

  //this part will append the anchor tag and remove it after automatic click
  document.body.appendChild(link);
  link.click();
  document.body.removeChild(link);
}

</script>
