谷歌应用脚本 select 特定列上传到目标表

Question

Total beginner here. I am trying to select columns A,B,C from spreadsheet B which has around 40K rows and 25 columns, to spreadsheet A which is a blank document. So, I have two spreadsheets. This code works fine but I want to select only the columns I need (columns including all the data, not just the headers).

function importdata() {  
let ss = SpreadsheetApp.openById("ID"); //SPREADSHEET TO COPY FROM  
let sheet = ss.getSheetByName("name"); //SHEET (TAB) TO COPY FROM  
sheet.getRange(1,1,sheet.getLastRow(),sheet.getLastColumn()).getValues();

let ssThis = SpreadsheetApp.getActiveSpreadsheet();
let sheetRawData = ssThis.getSheetByName("name"); //SHEET IN THE TARGET SPREADSHEET TO COPY TO
sheetRawData.getRange(1,1,sheetRawData.getLastRow());
}

Any idea as to how I can add this into the code above? Many thanks!

Answer 1

You can create an array of selected columns and get / set the values for the ranges corresponding to those columns:

function importSelectedColumns() {  
  
  let selectedColumns = [1, 3, 5];
  
  let ss = SpreadsheetApp.openById("ID"); //SPREADSHEET TO COPY FROM  
  let sheet = ss.getSheetByName("name"); //SHEET (TAB) TO COPY FROM  
  let ssThis = SpreadsheetApp.getActiveSpreadsheet();
  let sheetRawData = ssThis.getSheetByName("name"); //SHEET IN THE TARGET SPREADSHEET TO COPY TO
  
  selectedColumns.forEach(function(column){
    let data = sheet.getRange(1,column, sheet.getLastRow(),1).getValues();
    sheetRawData.getRange(1,column, sheet.getLastRow(), 1).setValues(data);    
  }) 
}

Explanation:

• forEach() is one of several possibilities to loop through several columns subsequently.
• getRange(row, column, numRows, numColumns) lets you specify the number and amount of columns to retrieve.
• setValues(values) allows you to import the data from one range into another one.
• Note: The range dimensions of the origin and destination ranges need to match.

I'd propose the native approach with range.copyTo(range) :

function copy_cols() {
  var cols = ['a', 'c', 'd', 'x'];                // columns to copy

  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var src_sheet = ss.getSheetByName('Sheet1');    // source sheet
  var dest_sheet = ss.getSheetByName('Sheet2');   // destination sheet

  for (var col of cols) {
    var range = col + ':' + col;                  // a -> 'a:a', b -> 'b:b', etc
    var src_range = src_sheet.getRange(range);
    var dest_range = dest_sheet.getRange(range);
    src_range.copyTo(dest_range);
  }
}
