I am using ag-grid and using its “export to excel” feature. I am exporting a column which is a datetime type. I am basically doing as I (very briefly) outlined in my answer here (https://stackoverflow.com/a/49523800/1082063) to another users question. It works well, except for one glitch.
If an AG-grid cell value is null, i.e. the cell empty, I want the cell in the exported Excel workbook to also be empty. However, when the “null” value is returned for a cell, ag-grid puts in a cell in the workbook with
<Data ss:Type="DateTime"></Data>, which gets interpreted by Excel as 1900-01-00.
Any way around this?
Format the cells as
yyyy-mm-dd;;; . A cell rendered blank by formatting exports a blank cell.
