Update the comments of multiple cells

The setComment method allows adding comments to various cells simultaneously by passing an object as a parameter. That helps to prevent multiple undesirable entries in the spreadsheet history.

// Create the spreadsheet
let worksheets = jspreadsheet(document.getElementById('spreadsheet'), {
    worksheets: [{
        minDimensions: [10,10]
        allowComments: true,
    }],
});

worksheets[0].setComments({ A1: 'Comment on A1', B1: 'Comments on B1' });

Enterprise Extensions

Multiple comments in the same grid cell

JSS Enterprise offers an extension that enables multiple comments within a single grid cell.
