在 Google 表格单元格 (GAS) 中打印未指定数量的数组内容

Question

I am collecting information from a database, based on a filter and is stored in an array of arrays. Once this information is collected I want to be able to print this data onto a new sheet like this:

___________________________________  
|*****|John Buck, Associate, Luxura|
------------------------------------
|*****|Jane Doe, Manager, Eclipse  |
------------------------------------
|*****|Jim Bob, Executive, Lokia   |
------------------------------------
|*****|Suzzy Sue, Director, RoomX  |
___________________________________

The most important part is that each time I run this function the array may be a different size, so I need it to continue through the array until all records have been printed down the sheet. I've tried a few things, but I am only used to using forEach or for loops when there is a condition, where as this one would just print the specified info in every array.

function testArray() {
  var activeSpreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  var activeSheet = activeSpreadsheet.getActiveSheet();
  var activeRange = activeSpreadsheet.getActiveRange();
  var activeCell = activeSpreadsheet.getActiveCell();

  var startCell = activeSheet.getRange(5, 4);
  var ratingStartCell = activeSheet.getRange(5, 3);

  var newArray = [
    ["John Buck", "*****", "Associate", "Luxura"][
      ("Jane Doe", "****", "Manager", "Eclipse")
    ][("Jim Bob", "***", "Executive", "lokia")][
      ("Suzzy Sue", "*****", "Director", "RoomX")
    ],
  ];

  newArray.forEach((r, o) => {
    startCell.setValues(
      newArray[r][0] +
        ", " +
        newArray[r][2] +
        ", " +
        newArray[r][3] +
        ", " +
        newArray[r][4]
    );
  });

  newArray.forEach((r, o) => {
    ratingStartCell.setValues(newArray[r][2]);
  });
}

Answer 1

You could post the newArray to activeSheet in one go using the setValues(values) method .

This is more efficient than writing to the sheet on cell at a time. See Best Practices .

activeSheet.getRange(1, 1, newArray.length, newArray[0].length).setValues(newArray);

The size of the array does not need to be specified. newArray.length is the number of rows and newArray[0].length is the number of columns.

You need to be careful when constructing the array: each row must have the same number of columns. If the number of columns is different, you'll get an error and the setValues() will fail.

Answer 2

By the way, I modified your array. I'm not sure why it contains "()", you can refer to JavaScript Array to learn more on how to declare and use arrays.

You can refer to this sample code:

function testArray() {
  var activeSpreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  var activeSheet = activeSpreadsheet.getActiveSheet();
  Logger.log(activeSheet.getSheetName());

  var newArray = [
    ["John Buck", "*****", "Associate", "Luxura"],
    ["Jane Doe", "****", "Manager", "Eclipse"],
    ["Jim Bob", "***", "Executive", "lokia"],
    ["Suzzy Sue", "*****", "Director", "RoomX"]
  ];
  Logger.log(newArray);

  //Create new array that will contain expected row values
  var rowValues = [];
  newArray.forEach((r,o)=>{
    //Push a 2-D array, Col1 will be the rating (****) while Col2 will be the remaining strings
    //separated by a comma and space
    rowValues.push([r[1], r[0]+", "+r[2]+", "+r[3]]);    
  });
  Logger.log(rowValues);
  //Set the values for the selected range, using the size of the 2-d array starting from row 5.
  activeSheet.getRange(5,3,rowValues.length,rowValues[0].length).setValues(rowValues);
 
}

What it does?

1. After fixing your array, I created a new array rowValues which will contain 2 information:
   • Rating
   • Concatenated strings separated by a comma and a space.
2. Once I have created the desired grouping and output for each row. I now set the values of the selected range based on the rowValues created using Sheet.getRange(row, column, numRows, numColumns) and Range.setValues(values)

I set the start row to 5 and start column to 3 based on your earlier example. Feel free to adjust your start row and column index based on your preference.
