With the following Google Apps Script you can grab the LIBOR value and added it to a new sheet. Goto the script editor:
and add this script:
function myCustomCalculation() {
//set active spreadsheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
// flush the spreadsheet before using it
SpreadsheetApp.flush();
// get both the sheets
var sh0 = ss.getSheets()[0], sh1 = ss.getSheets()[1];
// get cell value from sheet[0]
var cell = sh0.getRange("D2").getValues()[0];
// add libor value to other sheet
sh1.appendRow([new Date(), cell]);
}
The clue to the story is to create a time based trigger:
and set the trigger to execute at 5-6 pm:
See the example file I´ve created: LIBOR. I've added an extra menu item, so that you can execute the script this way.
