CSV Export

Export grid data to a downloadable CSV file using the exportToCsv utility from core. It respects column visibility and applies valueFormatter so the exported values match what the user sees.

Quick Example

React

import { exportToCsv } from '@alaarab/ogrid-react-radix';

function ExportButton({ data, columns }: { data: Row[]; columns: IColumnDef<Row>[] }) {
  const handleExport = () => {
    exportToCsv(
      data,
      columns.map((col) => ({ columnId: col.columnId, name: col.name })),
      (item, columnId) => {
        const col = columns.find((c) => c.columnId === columnId);
        if (!col) return '';
        const value = col.valueGetter ? col.valueGetter(item) : (item as Record<string, unknown>)[columnId];
        return col.valueFormatter ? col.valueFormatter(value, item) : String(value ?? '');
      },
      'my-data.csv'
    );
  };

  return <button onClick={handleExport}>Export to CSV</button>;
}

Switching UI libraries

The OGrid component has the same props across all React UI packages. To switch, just change the import:

• Radix (lightweight, default): from '@alaarab/ogrid-react-radix'
• Fluent UI (Microsoft 365 / SPFx): from '@alaarab/ogrid-react-fluent' - wrap in <FluentProvider>

How It Works

The exportToCsv Function

exportToCsv<T>(
  items: T[],
  columns: CsvColumn[],
  getValue: (item: T, columnId: string) => string,
  filename?: string
): void

Parameter	Type	Description
items	T[]	The row data to export
columns	CsvColumn[]	Array of { columnId, name } defining which columns to include and their header names
getValue	(item, columnId) => string	Function to extract the display value for each cell
filename	string (optional)	Download filename (default: 'export.csv')

The function:

1. Builds a CSV header row from columns[].name.
2. Iterates over each item and calls getValue for each column.
3. Escapes values containing commas, quotes, or newlines.
4. Triggers a browser download with the specified filename.

Context Menu Integration

When cellSelection is enabled (the default), the context menu does not include a dedicated "Export to CSV" item. Use the exportToCsv utility directly from a toolbar button or custom UI element.

Exporting Visible Columns Only

Filter the columns array to only include visible columns before passing to exportToCsv.

const visibleCols = columns.filter((col) => visibleColumns.has(col.columnId));

exportToCsv(
  data,
  visibleCols.map((col) => ({ columnId: col.columnId, name: col.name })),
  getValue,
  'filtered-export.csv'
);

Formatted Values

Use valueFormatter in your getValue function so exported data matches the display. For example, a currency column that shows "$1,234.56" in the grid will export that same string.

const getValue = (item: Row, columnId: string) => {
  const col = columns.find((c) => c.columnId === columnId)!;
  const raw = col.valueGetter ? col.valueGetter(item) : (item as any)[columnId];
  return col.valueFormatter ? col.valueFormatter(raw, item) : String(raw ?? '');
};
