Filter data by column K in Google Script Editor (Google Sheets)

Question

In this example, I have a set of data from a Google Sheet (4Cat) feeding into another sheet (ImportFeeder) where I am running my Google Script.

At the end of the script below, how can I insert a filter script to sort the data by Row K? (only showing iPad products)

function myFunction() {
var sss = SpreadsheetApp.openById('1kL96dRm3Z8XBtMXnSzUARxR1b34-njlkZQ1sU0c3g1s'); //replace with source ID
var ss = sss.getSheetByName('4cat'); //replace with source Sheet tab name
var range = ss.getRange('A:I'); //assign the range you want to copy
var data = range.getValues();

var tss = SpreadsheetApp.openById('1u7547KaniKHLUJn2v-ezN4l8ZcxE4viCFcoxsA904MI'); //replace with destination ID
var ts = tss.getSheetByName('Sheet1'); //replace with destination Sheet tab name
ts.getRange(ts.getLastRow()+1, 1, data.length, data[0].length).setValues(data);

var range = ts.getRange(ts.getLastRow()+1, 1, data.length, data[0].length)
var rawData = range.getValues()     // get value from spreadsheet 2
var data = []                       // Filtered Data will be stored in this array
for (var i = 0; i< rawData.length ; i++){
if(rawData[i][10] == "iPad")            // Check to see if column K says ipad if not skip it
{
data.push(rawData[i])
}
}
}

(Cannot read property length from undefined)

Required - Successful sheet to sheet import, filter data by Row K within Google Scripts. Add a clear() sheet function to the top of the script, as this will be running daily and the sheet needing clearing before daily import.

Answer 1

Why not using a custom filter function? Added a .toLowerCase() to match "ipad" case insensitive.

function myFunction() {
var sss = SpreadsheetApp.openById('1kL96dRm3Z8XBtMXnSzUARxR1b34-njlkZQ1sU0c3g1s'); //replace with source ID
var ss = sss.getSheetByName('4cat');   //replace with source Sheet tab name
var range = ss.getRange('A:V');        //assign the range you want to copy
var rawData = range.getValues()        // get value from spreadsheet 1
var data = rawData.filter(isColKiPad); // Filtered Data will be stored in this array
var tss = SpreadsheetApp.openById('1u7547KaniKHLUJn2v-ezN4l8ZcxE4viCFcoxsA904MI'); //replace with destination ID
var ts = tss.getSheetByName('Sheet1'); //replace with destination Sheet tab name
ts.getRange(2,1,ts.getLastRow() - 1,ts.getLastColumn()).clear(); // Assuming header is in the first row, clears sheet but header
ts.getRange(2, 1, data.length, data[0].length).setValues(data);
};
// Change both to ts.getRange(1,1,[...] if there's no header row
function isColKiPad(arr) {
  return arr[10].toLowerCase() == "ipad";
};

Did you consider using a Spreadsheet formula? You could try a combination of =IMPORTRANGE(spreadsheet_key, string_range) and QUERY(data, query, [header]) to import your range already filtered :

=QUERY(IMPORTRANGE("1kL96dRm3Z8XBtMXnSzUARxR1b34-njlkZQ1sU0c3g1s";"4cat!A:V");"SELECT * WHERE Col11 = 'iPad'")

You won't even need to clear your sheet this way.

Answer 2

you can add this to your original code:

filterByText(rawData, 10, iPad);

It will work as long as you add this function after your myFunction function:

function filterByText(data, columnIndex, values) {
    var value = values;
    if (data.length > 0) {
        if (typeof columnIndex != "number" || columnIndex > data[0].length) {
            throw "Please, can you choose a valid column index?";
        }
        var r = [];
        if (typeof value == "string") {
            var reg = new RegExp(escape(value).toUpperCase());
            for (var i = 0; i < data.length; i++) {
                if (columnIndex < 0 && escape(data[i].toString()).toUpperCase().search(reg) != -1 || columnIndex >= 0 && escape(data[i][columnIndex].toString()).toUpperCase().search(reg) != -1) {
                    r.push(data[i]);
                }
            }
            return r;
        } else {
            for (var i = 0; i < data.length; i++) {
                for (var j = 0; j < value.length; j++) {
                    var reg = new RegExp(escape(value[j]).toUpperCase());
                    if (columnIndex < 0 && escape(data[i].toString()).toUpperCase().search(reg) != -1 || columnIndex >= 0 && escape(data[i][columnIndex].toString()).toUpperCase().search(reg) != -1) {
                        r.push(data[i]);
                        j = value.length;
                    }
                }
            }
            return r;
        }
    } else {
        return data;
    }
}

Above is the code used by Google Apps Script's ArrayLib library filterByText method. I literally just copied it and made the throw friendlier.

Your full code could look something like this:

function myFunction() {
  var sss = SpreadsheetApp.openById('1kL96dRm3Z8XBtMXnSzUARxR1b34-njlkZQ1sU0c3g1s'); //replace with source ID
  var ss = sss.getSheetByName('4cat'); //replace with source Sheet tab name
  var range = ss.getRange('A:I'); //assign the range you want to copy
  var data = range.getValues();

  var tss = SpreadsheetApp.openById('1u7547KaniKHLUJn2v-ezN4l8ZcxE4viCFcoxsA904MI'); //replace with destination ID
  var ts = tss.getSheetByName('Sheet1'); //replace with destination Sheet tab name
  ts.getRange(ts.getLastRow()+1, 1, data.length, data[0].length).setValues(data);

  var range = ts.getRange(ts.getLastRow()+1, 1, data.length, data[0].length)
  var rawData = range.getValues()     // get value from spreadsheet 2
  var data = filterByText(rawData, 10, iPad); // rawData is now sorted.
  range.clear();

  var powerRange = ts.getRange(ts.getLastRow()+1, 1, data.length, data[0].length);

  powerRange.setValues(data);
} 

function filterByText(data, columnIndex, values) {
    var value = values;
    if (data.length > 0) {
        if (typeof columnIndex != "number" || columnIndex > data[0].length) {
            throw "Please, can you choose a valid column index?";
        }
        var r = [];
        if (typeof value == "string") {
            var reg = new RegExp(escape(value).toUpperCase());
            for (var i = 0; i < data.length; i++) {
                if (columnIndex < 0 && escape(data[i].toString()).toUpperCase().search(reg) != -1 || columnIndex >= 0 && escape(data[i][columnIndex].toString()).toUpperCase().search(reg) != -1) {
                    r.push(data[i]);
                }
            }
            return r;
        } else {
            for (var i = 0; i < data.length; i++) {
                for (var j = 0; j < value.length; j++) {
                    var reg = new RegExp(escape(value[j]).toUpperCase());
                    if (columnIndex < 0 && escape(data[i].toString()).toUpperCase().search(reg) != -1 || columnIndex >= 0 && escape(data[i][columnIndex].toString()).toUpperCase().search(reg) != -1) {
                        r.push(data[i]);
                        j = value.length;
                    }
                }
            }
            return r;
        }
    } else {
        return data;
    }
}
