我如何从特定行和列读取数据到特定行和列从excel表到nodejs中的json格式

Question

我正在使用 xlsx 包。如果有的话，请推荐任何其他的包

我试过了，但我没有得到完整的数据

var sheet, jsonData,
    excelString = new Buffer(base64, 'base64').toString('binary'),
    workbook = excelParser.read(excelString, {type: 'binary'});

    if (workbook.Sheets['Sheet1']) {
      sheet = workbook.Sheets['Sheet1'];
      workbook.Sheets['Sheet1'] = sheet;
      jsonData = excelParser.utils.sheet_to_json(workbook.Sheets['Sheet1'], {});

Answer 1

你可以使用

npm install excel

使用这个。

var parseXlsx = require('excel');
parseXlsx('Spreadsheet.xlsx', function(err, data) {
  if(err) throw err;
    // data is an array of arrays
});

您也可以访问Converting excel file to json in nodejs

Note: Make sure your Excel file is not opened by any other software (especially Excel !).

编码愉快。

Answer 2

var XLSX = require('xlsx');
var workbook = XLSX.readFile('Test1.xlsx');

var first_sheet_name = workbook.SheetNames[0];

// to read the value of individual cell 
var address_of_cell = 'C4';
var worksheet = workbook.Sheets[first_sheet_name]; 
var desired_cell = worksheet[address_of_cell];
var desired_value = (desired_cell ? desired_cell.v : undefined);
console.log(desired_value);

请阅读 xlsx https://www.npmjs.com/package/xlsx 的文档以进一步澄清

Answer 3

var XLSX = require('xlsx');
var workbook = XLSX.readFile(path);
var sheet_name_list = workbook.SheetNames;
var xlData = XLSX.utils.sheet_to_json(workbook.Sheets[sheet_name_list[0]]);
 for (let i = 0; i < xlData.length; i++) {
            let employee_choice1 = xlData[i].employee_choice
            var employee_choice = employee_choice1.split(',')
//implement your condition

}
