Planilhas do Excel podem ser importadas para arquivos XDF usando rxImport por meio da interface ODBC do Excel. Considerando que o driver ODBC do Excel é instalado e configurado no Windows, um exemplo de código para a importação de uma planilha, "Plan1" da pasta de trabalho "C:/Data/ODBCTest.xlsx" seria:
#Define ODBC connection string.connectionStr <- "Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};DriverId=790;Dbq=C:/Data/ODBCTest.xlsx;DefaultDir=c:/Data;"
#Define ODBC query into workbook. The worksheet name must be followed by '$' and enclosed in [].
testExcel = "SELECT * FROM [Sheet1$]"
#Define ODBC data source for the import using the query and connection string.
excelDS<- RxOdbcData(sqlQuery = testExcel, connectionString=connectionStr)
#Define input workbook and output xdf file.
excelDS_XDF<- RxXdfData("testFromExcel.xdf")
#Import the workbook into the XDF
rxImport(excelDS, excelDS_XDF, overwrite=TRUE)
