# PDF Export - Customising Content

PDF Export uses Value Getters and, by default, [Value Formatters](https://www.ag-grid.com/react-data-grid/value-formatters/#formatting-for-export). Export callbacks can replace the resulting text without changing the values displayed in the grid.

## Customising Cell and Row Group Values

Use `processCellCallback` and `processRowGroupCallback` in `defaultPdfExportParams` to customise exported body cells and row groups.

```jsx
const processCellCallback = (params) => `_${params.value ?? ''}_`;
const processRowGroupCallback = (params) => `row group: ${params.node.key ?? ''}`;

<AgGridReact
    processCellCallback={processCellCallback}
    processRowGroupCallback={processRowGroupCallback}
/>
```

See below the functions on the `PdfExportParams` interface to customise exported grid cell and row group values.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `processCellCallback` | `Function` |  |  |  |
| `processRowGroupCallback` | `Function` |  |  |  |

The following example adds the prefix `row group: ` to row-group values and surrounds body-cell values with underscores in the exported PDF.

interface ResultData {
  athlete: string;

}

const GridExample = () => {
  const gridRef = useRef<AgGridReact<ResultData>>(null);
  const containerStyle = useMemo(() => ({ width: "100%", height: "100%" }), []);
  const gridStyle = useMemo(() => ({ height: "100%", width: "100%" }), []);
  const [rowData, setRowData] = useState<ResultData[]>([
    {
      athlete: "Asha Patel",
      country: "United Kingdom",
      sport: "Rowing",
      gold: 2,
    },
    {
      athlete: "Noah Williams",
      country: "United Kingdom",
      sport: "Cycling",
      gold: 1,
    },
    { athlete: "Sofia Rossi", country: "Italy", sport: "Swimming", gold: 3 },
    { athlete: "Marco Bianchi", country: "Italy", sport: "Fencing", gold: 1 },
  ]);
  const [columnDefs, setColumnDefs] = useState<ColDef[]>([
    { field: "athlete", minWidth: 180 },
    { field: "country", rowGroup: true, hide: true },
    { field: "sport", minWidth: 140 },
    { field: "gold" },
  ]);
  const defaultColDef = useMemo<ColDef>(() => {
    return {
      flex: 1,
      minWidth: 100,
    };
  }, []);
  const defaultPdfExportParams = useMemo<PdfExportParams>(() => {
    return {
      processCellCallback(params: ProcessCellForExportParams): string {
        return `_${params.value ?? ""}_`;
      },
      processRowGroupCallback(params: ProcessRowGroupForExportParams): string {
        return `row group: ${params.node.key ?? ""}`;
      },
    };
  }, []);

  const onBtExport = useCallback(() => {
    gridRef.current!.api.exportDataAsPdf();
  }, []);

  return (
    <AgGridProvider modules={modules}>
      <div style={containerStyle}>
        <div className="example-wrapper">
          <button onClick={onBtExport}>Export to PDF</button>

          <div style={gridStyle}>

              groupDefaultExpanded={-1}
              defaultPdfExportParams={defaultPdfExportParams}
            />
          </div>
        </div>
      </div>
    </AgGridProvider>
  );
};

const root = createRoot(document.getElementById("root")!);
root.render(
  <StrictMode>
    <GridExample />
  </StrictMode>,
);
```

## Customising Column Headers and Group Header Values

Use `processHeaderCallback` and `processGroupHeaderCallback` to customise exported column headers and column-group headers.

```jsx
const processHeaderCallback = (params) => `header: ${params.api.getDisplayNameForColumn(params.column, null)}`;
const processGroupHeaderCallback = (params) =>
    `group header: ${params.api.getDisplayNameForColumnGroup(params.columnGroup, null)}`;

<AgGridReact
    processHeaderCallback={processHeaderCallback}
    processGroupHeaderCallback={processGroupHeaderCallback}
/>
```

See below the functions on the `PdfExportParams` interface to customise exported column group headers and headers.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `processHeaderCallback` | `Function` |  |  |  |
| `processGroupHeaderCallback` | `Function` |  |  |  |

The following example prefixes exported headers with `header: ` and exported group headers with `group header: `.

These callbacks return text. To style the processed result, use `processStyleCallback`; its `value` is the final exported string.
