How to iterate through multiple sheets in Excel file, retrieve sheet name and data

Hi,

  I am new to Talend and trying to read through multiple dynamic worksheets in the excel workbook and load data to table. 

tFileInputExcel -> tMap -> tOracleOutput works to load the data from all sheets to table.

 

But I need to get each worksheet name and check the name to derive a boolean value in addition to load the data in worksheet to table. The table columns looks like below

 

 SheetColumn1;SheetColumn2;...;Src_Sheet_Name;Etl_Flag

 

Any help or comments are helpful.

Hi,

In the tMap component you may access the current sheetname using the following expression (replace the tFileInputExcel # by yours):

((String)globalMap.get("tFileInputExcel_4_CURRENT_SHEET")) 

So, you can compare its value with what you want to populate the boolean field as desired.

@jlolling, good to know but in this case, tFileInputExcel is enough.

Thats easy. Use the component tFileExcelSheetList to iterate through the sheets and use within the iteration tFileExcelSheetInput to fetch the data. You can use the return value from the tFileExcelSheetList using as sheet name for tFileExcelSheetInput. Both referencing to tFileExcelWorkbookOpen in which you open the file.
