How to set cell type?

Given some data like:

const workbook = new Excel.Workbook();
const sheet = workbook.addWorksheet('My Sheet');
const rows = [
    [1, 'Bob', true],
    [2, 'Jake', false]
];

sheet.addRows(rows);

How can I make the sheet column types in the excel file end up being Excel.ValueType.Number, Excel.ValueType.String, Excel.ValueType.ValueType.Boolean?

Is there any update on this? It will be very useful for cases where number is being stored as string or when date timezone needs to be changed on server side.

you can change the cell’s format by the following code (in this example I change all cells in col 1 (A) to text format: const cell = worksheet.getColumn(1); cell.eachCell((c, rowNumber) => { c.numFmt = '@'; });
