using System.Data;
using System.Globalization;
// ...

spreadsheetControl1.Options.Culture = new CultureInfo("fr-FR");
var workbook = spreadsheetControl1.Document;

var worksheet = workbook.Worksheets.ActiveWorksheet;
var dataTable = new DataTable();
dataTable.Columns.Add(new DataColumn("Column1", typeof(string)));
worksheet["A1"].Value = new DateTime(2022, 05, 30);
var exporter = worksheet.CreateDataTableExporter(worksheet["A1"], dataTable, false);
exporter.Options.DefaultCellValueToStringConverter.PreferredCulture = new CultureInfo("fr-FR");
exporter.Options.DefaultCellValueToStringConverter.SetPreferredNumberFormatLocal(spreadsheetControl1.Document, "mmm-aa");
exporter.Export();
string result = dataTable.Rows[0].Field<string>("Column1");

The CellValueToStringConverter.SetPreferredNumberFormat method allows you to obtain or specify a number format in the invariant culture.
