//You can also convert the range e.g: [0,0,0,0] to cell address by using ssObj.getAlphaRange()
// ssObj.getAlphaRange(0,0,0,0); // returns "A1"
Using updateCellVaue(), you can update value and format for single cell only. If you want to update multiple cells with unique value, you can use the ‘updateUniqueData()’ client-side method else use the ‘updateRange()’ method to update range of cells based on defined sheet settings.
