如何在 google 工作表 Apps 脚本中对以逗号分隔的多个数据进行 vlookup？

Question

我有 google sheet 来创建 vlookup。

Sheet 1

	G	H
1	Categories	Category ID
2	ab, ac, bd
3	ac
4	av, ab

Sheet 2

A	B	C
Category	Category slug	category Id
ab	/ab/	1
ac	/ac	2
av	/av	3

我想进行如下所示的 vlookup。

	G	H
1	Categories	Category ID
2	ab, ac, bd	1,2,bd
3	ac	2
4	av, ab	3,1

要求是：

映射/为单元格中的所有数据创建 vlookup
在 vlookup 数据不可用的地方反转相同的数据

我试图在脚本编辑器中创建一个函数。但是事情并没有像我预期的那样发展。

function replace_category_with_id(){

  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("T");
  var total = sheet.getLastRow();
  var range = sheet.getRange(2,7,total,1);
  var values = range.getValues();
  var asheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("A");
  var atotal = asheet.getLastRow();
  var arange = asheet.getRange(2,1,atotal-1,3);
  var avalues = arange.getValues();
  
  //Create an array variable result
  var results =[{}];

  //Run a for loop for the values in the T Spreadsheet
  for(var i=0; i<values.length-1; i++)
  {
    //Split multiple data in a cell
    var splitdata = values[i].toString().split(",");
    
    //Search if the individual data in splitdata is available
    for(var count=0; count<(splitdata.length); count++)
    {
      //Create a flag to check if the search has found the data
      var flag = 0;
      for(var n=0; n<avalues.length-1;n++)
    {
      //Logger.log(avalues[n]);
      if(splitdata[count] == avalues[n][0])
      {
        Logger.log(i);
        Logger.log(count);
        Logger.log(n);
        //results[i][count] = avalues[n][2];
        flag = 1;
      }
    }
    if(flag==0)
    {
      results[i][count] = splitdata[count];
    }

    }

    //Logger.log(values[i]);
     
  } 

  //Display Results array
  for(var i=0; i<=results.length; i++)
  {
    Logger.log(results[i]);
  }
}

我对您的代码进行了一些修改，并为每个过程添加了注释。

试试这个：

function replace_category_with_id(){
  //Retrieve Sheet1 data
  var sheet1 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1");
  var total = sheet1.getLastRow();
  var range = sheet1.getRange(2,7,total-1,1);
  var sheet1_values = range.getValues();
  //Retrieve Sheet2 data
  var sheet2 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet2");
  var atotal = sheet2.getLastRow();
  var arange = sheet2.getRange(2,1,atotal-1,3);
  var sheet2_values = arange.getValues();
  
  //Sheet2: Create object as lookup 
  var lookup = {};
  sheet2_values.forEach(element => {
    //Push each element and use Category as key and Category ID as value
    lookup[element[0]] =  element[2]  
  })

  var result = [];
  sheet1_values.forEach(element => {
    //Sheet1: Split each categories in the first column.
    var val = element[0].toString().split(",");
    var val_str = [];
    val.forEach(element2 => {
      //Sheet1: Check if Category exists in lookup, if not use Category
      if(lookup.hasOwnProperty(element2)){
        val_str.push(lookup[element2])
      }else{
        val_str.push(element2);
      }
    })
    //Combine results in an Array
    result.push([val_str.join(",")])
  })

  //Set values to sheets using the combined results.
  sheet1.getRange(2,8,total-1,1).setValues(result);
  
}
