CSV Export - AG Grid

Overview

AG Grid provides built-in CSV export functionality allowing you to export grid data to CSV files. You can export all data, filtered data, or selected rows with extensive customization options for formatting and content.

Basic Export

Export grid data using the API methods:

import { exportDataAsCsv } from 'ag-grid-community';

// Export with default settings
exportDataAsCsv(beans);

// Export with custom filename
exportDataAsCsv(beans, {
  fileName: 'my-export.csv'
});

Export Configuration

Default Export Params

Set default parameters for all CSV exports:

import { CsvExportParams } from 'ag-grid-community';

const gridOptions = {
  defaultCsvExportParams: {
    fileName: 'data-export',
    columnSeparator: ',',
    suppressQuotes: false,
    skipColumnHeaders: false,
    skipColumnGroupHeaders: true,
    allColumns: false,
    onlySelected: false,
    exportedRows: 'filteredAndSorted'
  } as CsvExportParams
};

Column Separator

Customize the delimiter between columns:

import { CsvExportParams } from 'ag-grid-community';

exportDataAsCsv(beans, {
  columnSeparator: ';'  // Use semicolon instead of comma
} as CsvExportParams);

// Tab-separated values
exportDataAsCsv(beans, {
  columnSeparator: '\t'
} as CsvExportParams);

Export Scope

Export Filtered Data

import { CsvExportParams } from 'ag-grid-community';

// Export only filtered and sorted rows (default)
exportDataAsCsv(beans, {
  exportedRows: 'filteredAndSorted'
} as CsvExportParams);

// Export all rows regardless of filter
exportDataAsCsv(beans, {
  exportedRows: 'all'
} as CsvExportParams);

Export Selected Rows

import { CsvExportParams } from 'ag-grid-community';

// Export only selected rows
exportDataAsCsv(beans, {
  onlySelected: true
} as CsvExportParams);

// Export selected rows across all pages
exportDataAsCsv(beans, {
  onlySelected: true,
  onlySelectedAllPages: true
} as CsvExportParams);

Export Specific Columns

import { CsvExportParams } from 'ag-grid-community';

// Export all columns in column definition order
exportDataAsCsv(beans, {
  allColumns: true
} as CsvExportParams);

// Export specific columns
exportDataAsCsv(beans, {
  columnKeys: ['athlete', 'age', 'country']
} as CsvExportParams);

// Export using column objects
const columns = [api.getColumn('athlete'), api.getColumn('age')];
exportDataAsCsv(beans, {
  columnKeys: columns
} as CsvExportParams);

Headers and Groups

Column Headers

import { CsvExportParams } from 'ag-grid-community';

// Skip column headers
exportDataAsCsv(beans, {
  skipColumnHeaders: true
} as CsvExportParams);

// Include column headers (default)
exportDataAsCsv(beans, {
  skipColumnHeaders: false
} as CsvExportParams);

Column Group Headers

import { CsvExportParams } from 'ag-grid-community';

// Include column group headers
exportDataAsCsv(beans, {
  skipColumnGroupHeaders: false
} as CsvExportParams);

// Skip column group headers (default)
exportDataAsCsv(beans, {
  skipColumnGroupHeaders: true
} as CsvExportParams);

Custom Processing

Process Cell Callback

Customize cell values during export:

import { ProcessCellForExportParams, CsvExportParams } from 'ag-grid-community';

const processCellCallback = (params: ProcessCellForExportParams): string => {
  const { value, column, node } = params;
  
  // Format dates
  if (column.getColId() === 'date' && value instanceof Date) {
    return value.toLocaleDateString();
  }
  
  // Format currency
  if (column.getColId() === 'price') {
    return `$${value.toFixed(2)}`;
  }
  
  return value;
};

exportDataAsCsv(beans, {
  processCellCallback: processCellCallback
} as CsvExportParams);

Process Header Callback

Customize column header text:

import { ProcessHeaderForExportParams, CsvExportParams } from 'ag-grid-community';

const processHeaderCallback = (params: ProcessHeaderForExportParams): string => {
  const { column } = params;
  
  // Use custom header names
  const headerMap: Record<string, string> = {
    'athlete': 'Athlete Name',
    'age': 'Age (years)',
    'country': 'Country of Origin'
  };
  
  return headerMap[column.getColId()] || column.getColDef().headerName || '';
};

exportDataAsCsv(beans, {
  processHeaderCallback: processHeaderCallback
} as CsvExportParams);

Process Group Header Callback

import { ProcessGroupHeaderForExportParams, CsvExportParams } from 'ag-grid-community';

const processGroupHeaderCallback = (params: ProcessGroupHeaderForExportParams): string => {
  const { columnGroup } = params;
  return columnGroup.getColGroupDef()?.headerName?.toUpperCase() || '';
};

exportDataAsCsv(beans, {
  processGroupHeaderCallback: processGroupHeaderCallback
} as CsvExportParams);

Process Row Group Callback

import { ProcessRowGroupForExportParams, CsvExportParams } from 'ag-grid-community';

const processRowGroupCallback = (params: ProcessRowGroupForExportParams): string => {
  const { node } = params;
  
  if (node.group) {
    return `Group: ${node.key} (${node.allChildrenCount} items)`;
  }
  
  return '';
};

exportDataAsCsv(beans, {
  processRowGroupCallback: processRowGroupCallback
} as CsvExportParams);

Row Filtering

Should Row Be Skipped

import { ShouldRowBeSkippedParams, CsvExportParams } from 'ag-grid-community';

const shouldRowBeSkipped = (params: ShouldRowBeSkippedParams): boolean => {
  const { node } = params;
  
  // Skip rows with incomplete data
  return !node.data.athlete || !node.data.country;
};

exportDataAsCsv(beans, {
  shouldRowBeSkipped: shouldRowBeSkipped
} as CsvExportParams);

Pinned Rows

import { CsvExportParams } from 'ag-grid-community';

// Skip pinned rows
exportDataAsCsv(beans, {
  skipPinnedTop: true,
  skipPinnedBottom: true
} as CsvExportParams);

// Include pinned rows (default)
exportDataAsCsv(beans, {
  skipPinnedTop: false,
  skipPinnedBottom: false
} as CsvExportParams);

Row Groups

import { CsvExportParams } from 'ag-grid-community';

// Skip row group headers
exportDataAsCsv(beans, {
  skipRowGroups: true
} as CsvExportParams);

// Include row group headers (default)
exportDataAsCsv(beans, {
  skipRowGroups: false
} as CsvExportParams);

Custom Content

Prepend and Append Content

import { CsvExportParams, CsvCustomContent } from 'ag-grid-community';

const prependContent: CsvCustomContent = [
  ['Company Report'],
  ['Generated:', new Date().toLocaleDateString()],
  []  // Empty row
];

const appendContent: CsvCustomContent = [
  [],
  ['Total Rows:', 'COUNT']
];

exportDataAsCsv(beans, {
  prependContent: prependContent,
  appendContent: appendContent
} as CsvExportParams);

Custom Content Below Row

import { ProcessRowGroupForExportParams, CsvExportParams, CsvCustomContent } from 'ag-grid-community';

const getCustomContentBelowRow = (params: ProcessRowGroupForExportParams): CsvCustomContent | undefined => {
  const { node } = params;
  
  if (node.group && node.footer) {
    return [[
      { data: { value: 'Subtotal:' } },
      { data: { value: node.aggData?.total || '' } }
    ]];
  }
  
  return undefined;
};

exportDataAsCsv(beans, {
  getCustomContentBelowRow: getCustomContentBelowRow
} as CsvExportParams);

Advanced Options

Quote Handling

import { CsvExportParams } from 'ag-grid-community';

// Suppress quotes around values
exportDataAsCsv(beans, {
  suppressQuotes: true  // No quotes, ensure no separator in values
} as CsvExportParams);

// Use quotes (default for proper CSV format)
exportDataAsCsv(beans, {
  suppressQuotes: false  // Values wrapped in quotes, escapes internal quotes
} as CsvExportParams);

Export Row Numbers

import { CsvExportParams } from 'ag-grid-community';

exportDataAsCsv(beans, {
  exportRowNumbers: true  // Include row number column
} as CsvExportParams);

Value Source

import { CsvExportParams, CellValueResolveFrom } from 'ag-grid-community';

// Export from underlying data (default)
exportDataAsCsv(beans, {
  valueFrom: 'data' as CellValueResolveFrom
} as CsvExportParams);

// Export pending batch edit values
exportDataAsCsv(beans, {
  valueFrom: 'batch' as CellValueResolveFrom
} as CsvExportParams);

// Export current editor values
exportDataAsCsv(beans, {
  valueFrom: 'edit' as CellValueResolveFrom
} as CsvExportParams);

Disable Export

Prevent CSV export:

const gridOptions = {
  suppressCsvExport: true  // Disable CSV export completely
};

File Naming

Static File Name

import { CsvExportParams } from 'ag-grid-community';

exportDataAsCsv(beans, {
  fileName: 'export-2024-03-04.csv'
} as CsvExportParams);

Dynamic File Name

import { ExportFileNameGetter, ExportFileNameGetterParams, CsvExportParams } from 'ag-grid-community';

const fileNameGetter: ExportFileNameGetter = (params: ExportFileNameGetterParams) => {
  const date = new Date().toISOString().split('T')[0];
  return `data-export-${date}`;
};

exportDataAsCsv(beans, {
  fileName: fileNameGetter
} as CsvExportParams);

Common Use Cases

Export with Custom Date Formatting

import { ProcessCellForExportParams, CsvExportParams } from 'ag-grid-community';

const processCellCallback = (params: ProcessCellForExportParams): string => {
  const { column, value } = params;
  
  // Format all date columns
  if (column.getColDef().cellDataType === 'date' && value) {
    const date = new Date(value);
    return date.toLocaleDateString('en-US', {
      year: 'numeric',
      month: 'long',
      day: 'numeric'
    });
  }
  
  return value;
};

exportDataAsCsv(beans, {
  processCellCallback: processCellCallback
} as CsvExportParams);

Export Selected Rows with Summary

function exportSelectedWithSummary() {
  const selectedRows = api.getSelectedRows();
  const count = selectedRows.length;
  
  exportDataAsCsv(beans, {
    onlySelected: true,
    prependContent: [['Selected Rows Export']],
    appendContent: [[], [`Total Selected: ${count}`]]
  });
}

Export to Server Instead of Download

import { getDataAsCsv, CsvExportParams } from 'ag-grid-community';

async function exportToServer() {
  const csvData = getDataAsCsv(beans, {
    allColumns: true,
    exportedRows: 'filteredAndSorted'
  } as CsvExportParams);
  
  if (csvData) {
    await fetch('/api/export', {
      method: 'POST',
      headers: { 'Content-Type': 'text/csv' },
      body: csvData
    });
  }
}

Export with Row Groups Expanded

import { CsvExportParams } from 'ag-grid-community';

// Expand all groups before export
api.expandAll();

exportDataAsCsv(beans, {
  skipRowGroups: false,  // Include group headers
  exportedRows: 'filteredAndSorted'
} as CsvExportParams);

// Collapse groups after export
api.collapseAll();

TypeScript Interfaces

// From exportParams.ts
export interface CsvExportParams extends ExportParams<CsvCustomContent> {
  columnSeparator?: string;
  suppressQuotes?: boolean;
}

export interface BaseExportParams {
  allColumns?: boolean;
  columnKeys?: (string | Column)[];
  rowPositions?: RowPosition[];
  fileName?: string | ExportFileNameGetter;
  exportedRows?: 'all' | 'filteredAndSorted';
  onlySelected?: boolean;
  onlySelectedAllPages?: boolean;
  skipColumnGroupHeaders?: boolean;
  skipColumnHeaders?: boolean;
  skipRowGroups?: boolean;
  skipPinnedTop?: boolean;
  skipPinnedBottom?: boolean;
  valueFrom?: CellValueResolveFrom;
  shouldRowBeSkipped?(params: ShouldRowBeSkippedParams): boolean;
  processCellCallback?(params: ProcessCellForExportParams): string;
  processHeaderCallback?(params: ProcessHeaderForExportParams): string;
  processGroupHeaderCallback?(params: ProcessGroupHeaderForExportParams): string;
  processRowGroupCallback?(params: ProcessRowGroupForExportParams): string;
}

// From csvExportApi.ts
export function getDataAsCsv(beans: BeanCollection, params?: CsvExportParams): string | undefined;
export function exportDataAsCsv(beans: BeanCollection, params?: CsvExportParams): void;

Best Practices

Use default export params for consistency

Set defaultCsvExportParams in gridOptions to ensure consistent exports across your application.

Format data appropriately

Use processCellCallback to format dates, numbers, and other data types for readability in CSV.

Handle special characters

Keep suppressQuotes: false (default) to properly escape commas, quotes, and newlines in cell values.

Consider large datasets

For very large exports, use exportedRows: 'filteredAndSorted' and encourage users to filter data first.

Provide clear file names

Use dynamic file names with dates or filters applied to help users organize their exports.
