Data Grid - Export

Easily export the rows in various file formats such as CSV, Excel, or PDF.

Enabling export

To enable the export menu, pass the GridToolbar component in the Toolbar component slot.

<DataGrid {...data} loading={loading} slots={{ toolbar: GridToolbar }} />

<DataGrid {...data} loading={loading} slots={{ toolbar: GridToolbar }} />

Press Enter to start editing

The export menu is provided in a stand-alone component named GridToolbarExport. You can use it in a custom toolbar component as follows.

function CustomToolbar() {
  return (
    <GridToolbarContainer>
      <GridToolbarExport />
    </GridToolbarContainer>
  );
}

Disabled format

You can remove an export format from the toolbar by setting its option property disableToolbarButton to true. In the following example, the print export is disabled.

<DataGrid
  slotProps={{ toolbar: { printOptions: { disableToolbarButton: true } } }}
/>

Exported columns

By default, the export will only contain the visible columns of the Data Grid. There are a few ways to include or hide other columns.

Set the disableExport attribute to true in GridColDef for columns you don't want to be exported.

<DataGrid columns={[{ field: 'name', disableExport: true }, { field: 'brand' }]} />

Set allColumns in export option to true to also include hidden columns. Those with disableExport=true will not be exported.

<DataGrid slotProps={{ toolbar: { csvOptions: { allColumns: true } } }} />

Set the exact columns to be exported in the export option. Setting fields overrides the other properties. Such that the exported columns are exactly those in fields in the same order.

<DataGrid slotProps={{ toolbar: { csvOptions: { fields: ['name', 'brand'] } } }} />

By default, the Data Grid exports the selected rows if there are any. If not, it exports all rows except the footers (filtered and sorted rows, according to active rules), including the collapsed ones.

Customizing the rows to export

Alternatively, you can set the getRowsToExport function and export any rows you want, as in the following example. The grid exports a few selectors that can help you get the rows for the most common use-cases:

Selector	Behavior
`gridRowIdsSelector`	The rows in their original order.
`gridSortedRowIdsSelector`	The rows after applying the sorting rules.
`gridFilteredSortedRowIdsSelector`	The rows after applying the sorting rules, and the filtering rules.
`gridExpandedSortedRowIdsSelector`	The rows after applying the sorting rules, the filtering rules, and without the collapsed rows.
`gridPaginatedVisibleSortedGridRowIdsSelector`	The rows after applying the sorting rules, the filtering rules, without the collapsed rows and only for the current page (Note: If the pagination is disabled, it will still take the value of `page` and `pageSize`).

When using Row grouping, it can be useful to remove the groups from the CSV export.

CSV export

Exported cells

When the value of a field is an object or a renderCell is provided, the CSV export might not display the value correctly. You can provide a valueFormatter with a string representation to be used.

<DataGrid
  columns={[
    {
      field: 'progress',
      valueFormatter: (value) => `${value * 100}%`,
      renderCell: ({ value }) => <ProgressBar value={value} />,
    },
  ]}
/>

File encoding

You can use csvOptions to specify the format of the export, such as the delimiter character used to separate fields, the fileName, or utf8WithBom to prefix the exported file with UTF-8 Byte Order Mark (BOM). For more details on these options, please visit the csvOptions API page.

<GridToolbarExport
  csvOptions={{
    fileName: 'customerDataBase',
    delimiter: ';',
    utf8WithBom: true,
  }}
/>

Escape formulas

By default, the formulas in the cells are escaped. This is to prevent the formulas from being executed when the CSV file is opened in Excel.

If you want to keep the formulas working, you can set the escapeFormulas option to false.

<DataGrid slotProps={{ toolbar: { csvOptions: { escapeFormulas: false } } }} />

// or

<GridToolbarExport csvOptions={{ escapeFormulas: false }} />

Print export

Modify the Data Grid style

By default, the printed grid is equivalent to printing a page containing only the Data Grid. To modify the styles used for printing, such as colors, you can either use the @media print media query or the pageStyle property of printOptions.

For example, if the Data Grid is in dark mode, the text color will be inappropriate for printing (too light).

With media query, you have to start your sx object with @media print key, such that all the style inside are only applied when printing.

<DataGrid
  sx={{
    '@media print': {
      '.MuiDataGrid-main': { color: 'rgba(0, 0, 0, 0.87)' },
    },
  }}
  {/* ... */}
/>

With pageStyle option, you can override the main content color with a more specific selector.

<DataGrid
  slotProps={{
    toolbar: {
      printOptions:{
        pageStyle: '.MuiDataGrid-root .MuiDataGrid-main { color: rgba(0, 0, 0, 0.87); }',
      }
    }
  }}
  {/* ... */}
/>

Customize grid display

By default, the print export displays all the DataGrid. It is possible to remove the footer and the toolbar by setting respectively hideFooter and hideToolbar to true.

<GridToolbarExport
  printOptions={{
    hideFooter: true,
    hideToolbar: true,
  }}
/>

If rows are selected when exporting, the checkboxes will not be included in the printed page. To export the checkboxes you can set includeCheckboxes to true.

<GridToolbarExport
  printOptions={{
    includeCheckboxes: true,
  }}
/>

For more options to customize the print export, please visit the printOptions API page.

Custom export format

You can add custom export formats by creating your own export menu. To simplify its creation, you can use <GridToolbarExportContainer /> which contains the menu logic. The default <GridToolbarExport /> is defined as follow:

const GridToolbarExport = ({ csvOptions, printOptions, ...other }) => (
  <GridToolbarExportContainer {...other}>
    <GridCsvExportMenuItem options={csvOptions} />
    <GridPrintExportMenuItem options={printOptions} />
  </GridToolbarExportContainer>
);

Each child of the <GridToolbarExportContainer /> receives a prop hideMenu to close the export menu after the export. The demo below shows how to add a JSON export.

Excel export

This feature relies on exceljs. The Excel export allows translating columns' type and tree structure of a DataGrid to an Excel file.

Columns with types 'boolean', 'number', 'singleSelect', 'date', and 'dateTime' are exported in their corresponding type in Excel. Please ensure the rows values have the correct type, you can always convert them as needed.

Customization

Customizing the columns

You can use the columnsStyles property to customize the column style. This property accepts an object in which keys are the column field and values an exceljs style object.

This can be used to specify value formatting or to add some colors.

<GridToolbarExport
  excelOptions={{
    columnsStyles: {
      // replace the dd.mm.yyyy default date format
      recruitmentDay: { numFmt: 'dd/mm/yyyy' },
      // set this column in green
      incomes: { font: { argb: 'FF00FF00' } },
    },
  }}
/>

Customizing the document

You can customize the document using two callback functions:

exceljsPreProcess called before adding the rows' dataset.
exceljsPostProcess called after the dataset has been exported to the document.

Both functions receive { workbook, worksheet } as input. They are exceljs objects and allow you to directly manipulate the Excel file.

Thanks to these two methods, you can modify the metadata of the exported spreadsheet. You can also use it to add custom content on top or bottom of the worksheet, as follows:

function exceljsPreProcess({ workbook, worksheet }) {
  workbook.created = new Date(); // Add metadata
  worksheet.name = 'Monthly Results'; // Modify worksheet name

  // Write on first line the date of creation
  worksheet.getCell('A1').value = `Values from the`;
  worksheet.getCell('A2').value = new Date();
}

function exceljsPostProcess({ worksheet }) {
  // Add a text after the data
  worksheet.addRow(); // Add empty row

  const newRow = worksheet.addRow();
  newRow.getCell(1).value = 'Those data are for internal use only';
}

// ...

<GridToolbarExport
  excelOptions={{
    exceljsPreProcess,
    exceljsPostProcess,
  }}
/>;

Since exceljsPreProcess is applied before adding the content of the Data Grid, you can use it to add some informative rows on top of the document. The content of the Data Grid will start on the next row after those added by exceljsPreProcess.

To customize the rows after the Data Grid content, you should use exceljsPostProcess. As it is applied after adding the content, you can also use it to access the generated cells.

In the following demo, both methods are used to set a custom header and a custom footer.

Using a web worker

Instead of generating the Excel file in the main thread, you can delegate the task to a web worker. This method reduces the amount of time that the main thread remains frozen, allowing to interact with the grid while the data is exported in background. To start using web workers for the Excel export, first you need to create a file with the content below. This file will be later used as the worker script, so it must be accessible by a direct URL.

// in file ./worker.ts
import { setupExcelExportWebWorker } from '@mui/x-data-grid-premium';

setupExcelExportWebWorker();

The final step is to pass the path to the file created to GridToolbarExport or the API method:

<GridToolbarExport
  excelOptions={{
    worker: () => new Worker('/worker.ts'),
  }}
/>;

// or

apiRef.current.exportDataAsExcel({
  worker: () => new Worker('/worker.ts'),
});

If you are using Next.js or Webpack 5, use the following syntax instead. Make sure to pass the relative path, considering the current file, to the worker script.

<GridToolbarExport
  excelOptions={{
    worker: () => new Worker(new URL('./worker.ts', import.meta.url)),
  }}
/>;

// or

apiRef.current.exportDataAsExcel({
  worker: () => new Worker(new URL('./worker.ts', import.meta.url)),
});

It is not necessary to make the script public because Webpack will handle that automatically for you.

Since the main thread is not locked while the data is exported, it is important to give feedback for users that something is in progress. You can pass a callback to the onExcelExportStateChange prop and display a message or loader. The following demo contains an example using a Snackbar:

If you want to use the exceljsPreProcess and exceljsPostProcess options to customize the final spreadsheet, as shown in the Customization section above, you have to pass them to setupExcelExportWebWorker instead. This is necessary because functions cannot be passed to the web worker.

// Instead of
<GridToolbarExport
  excelOptions={{
    exceljsPreProcess,
    exceljsPostProcess,
  }}
/>;

// Do the following in the ./worker.ts file
setupExcelExportWebWorker({
  exceljsPreProcess,
  exceljsPostProcess,
});

Escape formulas

By default, the formulas in the cells are escaped. This is to prevent the formulas from being executed when the file is opened in Excel.

If you want to keep the formulas working, you can set the escapeFormulas option to false.

<DataGridPremium slotProps={{ toolbar: { excelOptions: { escapeFormulas: false } } }} />

// or

<GridToolbarExport excelOptions={{ escapeFormulas: false }} />
