TableBinding.rowCount property

Gets the number of rows in the table, as an integer value.

Hosts: Access, Excel, Word
Available in Requirement set TableBindings
Last changed in Selection 1.1
var rowCount = bindingObj.rowCount;

Return Value

The number of rows in the specified TableBinding object.


When you insert an empty table by selecting a single row in Excel 2013 and Excel Online (using Table on the Insert tab), both Office host applications create a single row of headers followed by a single blank row. However, if your add-in's script creates a binding for this newly inserted table (for example, by using the addFromSelectionAsync method), and then checks the value of the rowCount property, the value returned will differ depending whether the spreadsheet is open in Excel 2013 or Excel Online.

  • In Excel on the desktop, rowCount will return 0 (the blank row following the headers is not counted).

  • In Excel Online, rowCount will return 1 (the blank row following the headers is counted).

You can work around this difference in your script by checking if rowCount == 1, and if so, then checking if the row contains all empty strings.

In content add-ins for Access, for performance reasons the rowCount property always returns -1.


function showBindingRowCount() {
    Office.context.document.bindings.getByIdAsync("myBinding", function (asyncResult) {
        write("Rows: " + asyncResult.value.rowCount);
// Function that writes to a div with id='message' on the page.
function write(message){
    document.getElementById('message').innerText += message;
