Email the filter results from Google Apps Scripts

Question

I have the following function (btw I am new to Google Apps Scripts).

function testing(){
  let thisSpreadsheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(thirtyMinuteWorksheet).getDataRange().getValues()

  let filterData = thisSpreadsheet.filter(function (row,index) {
      return row[11] >= 30
  });


if(filterData.length > 0){
      MailApp.sendEmail({
      to: 'email@gmail.com',
      subject: 'test',
      body: filterData,
      noReply: true
      });
  }

the filter data filters the sheet and returns all the rows that match the logic. Id like to be able to email those rows. if I run this, i get and email with this. (plus more, shorten it for simplicity).

{10=[Ljava.lang.Object;@7f7f43f6, 179=[Ljava.lang.Object;@d387470, 
83=[Ljava.lang.Object;@5daa185f, 54=[Ljava.lang.Object;@39ca2a17, }

i can see this is an object but I couldnt find anything on their API that pointed me in the right direction as to how to covert this results into the actual values

ps

Yes, if i console.log filterData i do get the correct objects. any ideas?

Answer 1

I figured out a way, since this is an array of objects, I just converted that into and HTML function. as below.

I passed in my array results and added some headers as well.

function makeTableHTML(myArray,tableHeaders) {
    let result = "<table border=1>";
    result += "<tr>";
        for(var j=0; j<tableHeaders.length; j++){
            result += "<td>"+tableHeaders[j]+"</td>";
        }
        result += "</tr>";
    for(var i=0; i<myArray.length; i++) {
        result += "<tr>";
        for(var j=0; j<myArray[i].length; j++){
            result += "<td>"+myArray[i][j]+"</td>";
        }
        result += "</tr>";
    }
    result += "</table>";

    return result;
}

That gave me a way to add the return results into the sendmail function from Google Scripts.

You can try using join instead since the data you are sending is an array. Convert it to string to properly show the data.

Sample data:

Code:

  let filterData = thisSpreadsheet.filter(function (row, index) {
    return row[11] >= 30;
  });

  // Preprocesses filterData before sending mail
  filterData.forEach(function (row, index) {
    filterData[index] = filterData[index].join(",");
  });
  filterData = filterData.join("\n");


  if (filterData.length > 0) {
    MailApp.sendEmail({
      to: 'email@gmail.com',
      subject: 'test',
      body: filterData,
      noReply: true
    });
  }

Sample output:

One quick answer is to try and wrap filterData with JSON.stringify() , but you can't modify how it shows in the mail.

Code:

body: JSON.stringify(filterData),

Sample output:
