Create new row for each not empty column - google-apps-script

Question

I'm trying to convert an Excel macro to Google Apps Script. I would like to create a new row on a specific sheet for each not empty column in Google Spreadsheets.
My Inputsheet looks like the following:
ID | Inrellevant Column | Givenmoney | Takenmoney | Othermoney
1 | Data1 | 100 | 200 | 300
2 | Data2 | 400 | | 500
I want to create a new row in another sheet for each not empty cell, so the desired Outputsheet would be:
ID | Inrellevant Column | Moneycode | Amount
1 | Data1 | Givenmoney | 100
1 | Data1 | Takenmoney | 200
1 | Data1 | Othermoney | 300
2 | Data2 | Givenmoney | 400
2 | Data2 | Othermoney | 500
I tried the following:
Outputsheet.getRange('A2').offset(0, 0, Inputsheet.length).setValues(Inputsheet);
However I can't see to create a loop to create new rows for each not empty column.

Hoi Fred, assuming you want the output to appear from the top left cell onwards in the sheet 'Outputsheet', try this code:
function myFunction() {
var ss = SpreadsheetApp.getActive(),
source = ss.getSheetByName('Inputsheet'),
target = ss.getSheetByName('Outputsheet'),
arr = [
["ID", "Header 2nd col", "Moneycode", "Amount"]
],
data = source.getDataRange().getValues(),
headers = data[0];
data.splice(1)
.forEach(function (r) {
r.forEach(function (c, i) {
if (!isNaN(parseFloat(c)) && isFinite(c) && i > 1) {
arr.push([r[0], r[1], headers[i], c])
}
})
})
target.getRange(1, 1, arr.length, arr[0].length).setValues(arr);
}
See this example sheet where you can run the above script from the menu 'My Menu'....
