How to upload Excel to SAP(using ABAP)

ABAP code to upload XLSX file to SAP using ABAP. The method shown in the blog will work in SAP GUI and Webgui (program launched from Fiori Launchpad). This approach will also work with OData.

Code is based on class CL_FDT_XL_SPREADSHEET which can be instantiated using the file name and excel file in XSTRING variable. This processing of file as XSTRING is particularly useful in case of Fiori Apps, OData CREATE_STREAM method pass uploaded file already in XSTRING which can be simply passed on to class CL_FDT_XL_SPREADSHEET constructor.

After instantiating the class get list of worksheets in the file using IF_FDT_DOC_SPREADSHEET~GET_WORKSHEET_NAMES. Method GET_WORKSHEET_NAMES returns internal table. In most of the case, you would read the first worksheet name and call method IF_FDT_DOC_SPREADSHEET~GET_ITAB_FROM_WORKSHEET with worksheet name to get data in a dynamic internal table. However, if you have data over multiple worksheets then you would have to call method GET_ITAB_FROM_WORKSHEET in the loop for each worksheet.

There are some function modules (TEXT_CONVERT_XLS_TO_SAP) available in SAP which can help you read data from XLS/XLSX file but these are based on Office Integration and requires MS Office installed on your PC. Also, this Office Integration solution (along with a range of other features) is not supported in WebGUI. In other words, these FMs will only work when you are running your program in SAP WebGUI.

I have structured the logic in standalone SE38 program so you can copy-paste and have it ready for testing in your system. Obviously, you would have to adapt the code to use it in your application but you get the idea of how it works.

      1. Hi Pawan , Do you have sample code related to excel file upload from other ip. address like( //122.23.45.6/ ) which have folder with login password , our program should capable for login as well after passing login id pass words.

  1. Easily coded and very useful. The simplest XLSX upload implementation I have found on the web. Nice job! Thanks for sharing, you have been really helpful!

  2. Hi there, my business partner found out that there is a limit to the number of worksheets than can be uploaded. If you are just uploading one or two spreadsheets then this is a good tool.

    1. Hi, thank you for letting us know. Did you managed to find out the limit? I think this class is used in Data Migration Cockpit and I would imagine limit would be more than one or two.

      I have just uploaded a spreadsheet with 10 worksheets and I can see 10 worksheets in internal table lt_worksheets (line 111).

      1. what you have done to upload file via Fiori launchpad? I am getting Z drive filepath which doesnot exist. can you tell me what code you adapted to use it in your application

  3. Hello, does this upload method allow the excel file to be open on workstation when uploading to gui?

  4. Hi Pawan,
    The above code is very helpful for .xlsx files. Do you have similar code for .xls file with multiple worksheets also
    should work for Macro enabled workbook.

    I have a requirement where i have to read the macro enabled excel file (.xls) with multiple worksheets.

    Thanks
    Murthy

  5. Hi Pawan,

    I´m currently facing a weird problem with Method CONVERT_DEC_TIME_TO_HHMMSS in CL_FDT_XL_SPREADSHEET.
    I have time-formatted values (e.g. 10:45:03) in my Excel and by uploading them into SAP-tables some values get changed by the above method.
    I found that the method return invalid seconds (> 59) and sometimes (really! no pattern in behavior) swapped them (e.g. from “02” to “20”).
    I´m at SAP_BASIS/SAP_ABA 750 and wondering, if you have a solution?

    Thanks
    Sebastian

    1. Just to add to the above:
      A workaround would be to add a “T” before the timestamp, e.g. “T10:45:03”. Seems to me, that the SAP-method will handle the values then correctly.
      But unfortunately I didn´t found a way to change the value during export (using your coding via CL_SALV_EXPORT_TOOL_ATS_XLS to export any table to XLSX), since the structure is bound to a SAP-datafield type with a length of only 6 chars (HHMMSS), thus I can´t add a “T” w/o cutting the last digit.
      Any ideas?

  6. Hello Pawan, I tried to use cl_gui_frontend_services=>file_open_dialog from WEBGUI but it is throwing dump.

  7. Hi Pawan,

    I tried running your example, but only returned the message
    ‘File “_rels/.rels” not found in package’.

    Can you help me with this?

    regard.

    Kim.

  8. Hi Pawan, It was nice really nice blog that helped me. Can you please also upload code for Download data from SAP to Excel multiple tabs.
    We did using OLE object coding but it work from SAP GUI and not work from FIORI.
    Please help this is really urgent.

  9. Hi Pawan, Nice blog and very helpful. Please also share how to download SAP internal tables data to Excel multiple sheets. We did using OLE concepts but that not working when run from Fiori.
    Can you please help with any links or code as this is bit urgent.

  10. Any reason why you are using BIN parameter in GUI_UPLOAD and convert the binary data into xstring on the next step instead of using ASC parameter and have xstring directly after GUI_UPLOAD?

  11. very helpful – Thanks. Saved me good few hours of work time to write a database upload program.

  12. Thanks for this post and it was really helpful. I am trying to use this workaround so i can perform xls upload via FLP ( SAP WEB GUI app ). when am trying to do so, I am getting file error in FM GUI_UPLOAD – mapping file or directory could not be found. any pointers in this regard would be helpful
