How to access a cell value when the column has been defined with ag-grid value getters?

Question

If the ag-grid column definition has been defined with a value getter , the value gets displayed fine on the grid. However I was not able to find a way to access a value in a given cell if the cell is using cell value getters. Was trying to access the data through api.forEachNode, but it doesnt show the data. The only way I found was to export the data as CSV and then parse it using getDataAsCsv(params).

Is exporting the data the only way to access value of a column in a grid with a value getter?

Thanks in advance:)

You can always add a new property to your data.

Let's say I have a derived column to show the row index, where I am just returning row index.

Before returning from value getter, I can add this index to a new property called 'special'

{
   headerName: 'Special',
   maxWidth: 100,
   valueGetter: function(params) {
    params.node.data.special = params.node.rowIndex; // added property called special
    return params.node.rowIndex;
   }  
},  

You can now access this in api.forEachNode by doing -

this.gridApi.forEachNode(function(rowNode, index) {
     console.log(rowNode.data.special);
}
