Usage

1. Convert xlsx file to JSON

Sample files of this api: google docs or tencent docs

Commonjs

const XLSX2JSON = require('json-key-string-xlsx');
const xlsx2json = new XLSX2JSON();
const path = require('path');
const xlsxPath = path.join('./excel.xlsx');

const jsonData = xlsx2json.parse2json(xlsxPath);
// console.log(xlsx2json.parse2jsonCover);

ES Module

import xlsxJsonJs from 'json-key-string-xlsx';
const xlsx2json = new xlsxJsonJs();

UMD

<script src="https://cdn.jsdelivr.net/npm/xlsx@0.15.0/dist/xlsx.full.min.js"></script>
<script src="dist/json-key-string-xlsx.umd.min.js"></script>

<input type="file" name="file" id="file">
<script type="text/javascript">
  const xlsx2json = new jsonKeyStringXlsx();
  function handleFile(e) {
    const files = e.target.files, f = files[0];
    const reader = new FileReader();
    reader.onload = function(e) {
      const data = new Uint8Array(e.target.result);
      const jsonData = xlsx2json.parse2json(data, {type: 'array'});

    reader.readAsArrayBuffer(f);
  }
  document.getElementById('file').addEventListener('change', handleFile, false);

If some keys are overwritten, you can get details from xlsx2json.parse2jsonCover.

[ 'sheet name "main", row 12, value "disclaimer.content[1].c.a[0].b[0]"',
  'sheet name "main", row 16, value "fortest1.key"',
  'sheet name "main", row 21, value "fortest2[1].key2"',
  'sheet name "main", row 23, value "fortest3[].key"',
  'sheet name "main", row 25, value "fortest4.key"' ]

2. Convert JSON to xlsx file

The objData can also be an array of object.

const XLSX2JSON = require('json-key-string-xlsx');
const xlsx2json = new XLSX2JSON();
const objData = {
  "lang": "en",
  "userInfo": [
    {
      "name": "username",
      "nickname": "nickname"
    }
  ]
}
const aoaData = xlsx2json.json2XlsxByKey(objData);
// const aoaData = xlsx2json.json2XlsxByKey(objData, outputPath);
// const arrayBufferData = xlsx2json.json2XlsxByKey(objData, {type: 'array'});
