Overview
Every customer does their data maintenance in Excel and most of the SAP implementation or Support
projects would get a requirement to upload an excel file into SAP system either to store the data in data
dictionary or for reporting – Predominantly to display the excel data in ALV/ in table control (in both SAP GUI
and Webdynpro).
Most of our SAP ABAP consultants would have thought about this business scenario and posted a lot of
threads in SCN too ;). I see a lot of SCN responses recommends the consultants to convert excel (XLS) file
to Tab Limited File or Comma Separated File (CSV) and to use GUI_UPLOAD for uploading the data into
internal table. Most of the threads on this subject are left unanswered.
Besides, each ABAP consultants would have tried uploading the data using the following renowned function
modules and somehow managed to complete the requirement. Have a gaze at the disadvantages in the
classical approach in the following tabular representation,

Function Module Disadvantages
Does not handle the excel file. Excel file needs to be
GUI_UPLOAD converted to Tab Limited or Comma Separated file. – The
accuracy of the data and validating is pretty challenging
Data processing is very slow and mass data upload is not
TEXT_CONVERT_XLS_TO_SAP
optimistic.
ALSM_EXCEL_TO_INTERNAL_TABLE Data processing is very slow as it processes the data cell by
KCD_EXCEL_OLE_TO_INT_CONVERT cell and the count of rows and columns are fixed.

Table 1: This table illustrates the conventional SE37 function modules available to upload the excel file into our
application server.

In addition, the last three function modules are available as part of “SAP_APPL” component and hence those
are available only for logistics and accounting modules. The chances of using this three function module in
other modules like Solution Manager or CRM or SRM systems are not possible owing to their unavailability.
Furthermore, all the above Function Modules cannot be used in Webdynpro ABAP.
Beyond SAP’s technical difficulties, Microsoft excel has its own restrictions as the total number of rows is
limited to 65,536 and the XLS format is stored in Binary format. Owing to all this complexities, until
NetWeaver 7.0, SAP does not offer any standard way to upload Microsoft’s proprietary excel.
As of NW 7.02 (NetWeaver 7.0 Enhancement Package 2), SAP does support the excel operations (Import/
Export) due to the openness of excel since Microsoft office 2007. Click here to know the difference between
XLS and XLSX files.

Openness of Excel (XLSX Format)
XLSX is a default Excel 2007 workbook format. In reality, the XLSX document is a ZIP compressed archive
with a directory structure of XML text documents. As shown in the screenshot below, the XLSX file could be
extracted and the excel data are place in the following file path.
The following are an important XML files, we need to refer to fetch the data from ABAP,
1. Sheet Data – SPFLIxlsheet1.xml
2. Shared String – SPFLIsharedStrings.xml

Have a look at the pictorial representation of the folder structure,

Figure 1: The screenshot depicts the following activities,
1. Decompress/ extract the XLSX file
2. Folder Structure of XLSX
3. XML files where we could find the excel data

© 2012 SAP AG 4


Each excel sheet and its cells are parsed as an XML document. Every strings in excel are uniquely stored in
a separate XML document “sharedstrings.xml” and those indexes are maintained in the respective sheet
XMLs whereas the integer values are maintained in the sheet XML itself. Have a glimpse of it in the following
screenshots,

Figure 2: The topmost view illustrates the schema of sheet XML and shared string XML and the how the mapping takes
place. The lower view is a snapshot captured from the excel file.

Thus, the effort of reading excel is much simplified and now all we need to do is to read multiple XML files
from XLSX package to populate an internal table.

APIs for Office Applications
As of NetWeaver 7 Ehp2 (7.02), we have a different APIs to adapt to the openness of MS Office platform.
The following classes are as part of those,

Loads/ creates an XLSX document. This is the API we use in this document
CL_XLSX_DOCUMENT
to load the excel file into ABAP internal table.
CL_DOCX_DOCUMENT Loads/ creates an word document
CL_PPTX_DOCUMENT Loads/ creates presentations.

XLSX Import – How to
The following are the steps ought to be followed to upload the file into ABAP Internal Table, here you go…
1. Read the path of the uploaded file by offering a “File open dialog”
2. Load the content of the file
3. Load the package
4. Load the parts of the package
5. Load the Shared String XML and Sheet1 XML
6. Process the XMLs using XSL transformation

The aforesaid steps are applicable for Webdynpro ABAP too by having “Upload UI element” in place.

Step 1 – Read the path of uploaded file
Get the file open dialog (on hitting F1) using the static method browse_local_file_open from the class
cl_openxml_helper as shown in the following code snippet,
AT SELECTION-SCREEN ON VALUE-REQUEST FOR filename.
cl_openxml_helper=>browse_local_file_open(
iv_title = 'Select XLSX File'
iv_filename = ''
iv_extpattern = 'All files(*.*)|*.*' ).

This method gets you the path of the selected file in the string variable. You could achieve this using the
static method file_open_dialog in the class cl_gui_frontend_services,

CALL METHOD cl_gui_frontend_services=>file_open_dialog
EXPORTING window_title = 'Select XLSX File'
initial_directory = dir
file_filter = '*.xlsx'
multiselection = ''
CHANGING file_table = filetable
rc = i.
IF i = 1.
READ TABLE filetable INDEX 1 INTO ft.
srcpath = ft-filename.
ENDIF.

Step 2 – Load the file content
Initially, the content of the selected file path should be uploaded into our program using the static method
load_local_file( ) from the class cl_openxml_helper,
TRY.
mv_file_data = cl_openxml_helper=>load_local_file( lv_filename ).
CATCH cx_openxml_not_found.
ENDTRY.

This will get you a hexadecimal content. This could be also achieved using the removed GUI class, so called
cl_gui_frontend_services=>fui_upload. As this frontend classes is usable only in SAP GUI based
transactions (not for webdynpro), we use the XML helper class cl_openxml_helper, which could be used both
in SAP GUI programs and webdynpro applications.

Step 3 – Loading the Package
As I mentioned before, the entire XSLX file is wrapped up in a compressed package and which is not
readable unless we read the package. For loading the package, we have a class cl_xlsx_document which
has got unveiled since NW 702 (NetWeaver 7 Ehp 2).
TRY.
mo_package = cl_xlsx_document=>load_document( iv_data = mv_file_data ).
CATCH cx_openxml_format cx_openxml_not_found.
ENDTRY.

Step 4 – Loading the parts of the Package
The loaded package will be in the format shown below and for reading the data from excel sheet1 we need
to read the XML “sharedString.xml” from “XLSXSPFLIxl” and “sheet1.xml” from
“XLSXSPFLIxlworksheets” folder. As these files are present in the different folders; we need to differentiate
and identify the XML by means of package parts.

Figure 3: The above screenshot refers to the different folder paths where user could locate the required XMLs to
populate the excel rows and columns.

The following code snippet would let you locate the exact XML file.
TRY.
mo_parts = mo_package->get_parts( ).
ENDTRY.

Step 5 – Load the XMLs
We need to read “Sheet” and “Shared String” XML files which are wrapped up in the loaded package. These
files could be located using the part reference (refer step 4).
Read the “Sheet1 XML” by passing to the part number as “2” as shown in the code snippet below.
(load_xml_data is the method you could find in the example program)
CONSTANTS co_sheet_xml TYPE i VALUE 2.
DATA mv_sheet_data TYPE xstring.
mv_sheet_data = load_xml_data( co_sheet_xml ).

© 2012 SAP AG 7


Read the “Shared String XML” by passing to the part number as “3”,

CONSTANTS co_shared_str_xml TYPE i VALUE 3.
DATA mv_shared_data TYPE xstring.
mv_shared_data = load_xml_data( co_shared_str_xml ).

Method Implementation:
METHOD load_xml_data.
DATA lo_xml_part TYPE REF TO cl_openxml_part.
DATA lo_xml_part_uri TYPE REF TO cl_openxml_parturi.
DATA lv_uri TYPE string.

TRY.
lv_uri = mo_parts->get_part( 2 )->get_parts( )->get_part(
iv_xml_index )->get_uri( )->get_uri( ).

lo_xml_part_uri = cl_openxml_parturi=>create_from_partname( lv_uri ).
lo_xml_part = mo_package->get_part_by_uri( lo_xml_part_uri ).
rv_xml_data = lo_xml_part->get_data( ).
ENDTRY.
ENDMETHOD.

Step 6 – Process the XML – Less ABAP – More XSLT
XSLT: XSL stands for EXtensible Stylesheet Language, and is a style sheet language for XML documents
driven by W3C. XSLT stands for XSL Transformations. XSLT is a language for transforming XML documents
into other XML documents or other objects such as HTML, XML or XSL. Typically, input documents are XML
files, but anything from which the processor can build an XQuery and XPath Data Model can be used. The
original document is not changed; rather, a new document is created based on the content of an existing
one. XSLT is a Turing-complete language, meaning it can perform any calculation that can be performed by
a modern computer program.
For more information for XSLT refer http://www.w3schools.com/xsl/

XSLT in ABAP: The SAP XSLT processor is already available as part of the kernel since Basis release 6.10
with the specifications defined for the XSLT version 1.0. XSLT has a capability to transform the following,
 XML to XML
 XML to ABAP Internal Table
 ABAP Internal Tale to XML
 ABAP Internal Table to ABAP Internal Table

Click here to know more about ABAP XSLT Programming and gaze at the examples too.
To create XSLT Programs in ABAP go to TCode SE80  Right Click on the Package  Create  Other (1)
 Transformation  Enter the name of the transformation and choose the type as “XSLT”.

Figure 4: Captured from SE80 transaction while attempting to create the XSLT transformation.

Processing the Sheet and Shared String XML
The processing of XSL transformation is much faster than ABAP language and hence we are going to do
more XSLT and less ABAP for processing the XML data.
The XSLT will read the “sheet xml data” and map the cell indexes with the “shared string XML” to read the
cell data.
In XSLT, we can pass only one XML file as a source; whereas we have two XML documents (Sheet
XML and Shared String XML) which need to be desterilized to form an internal table. Hence we are going to
pass the sheet XML as a source for XSLT and shared String XML as a parameter my removing the XML
namespaces. For removing the namespaces we are going to create another transformation. (Our objective is
to read and process both the XMLs using a single XSLT program.)
TRY.
CALL TRANSFORMATION zben_shared_string_del_namesp
SOURCE XML mv_shared_data
RESULT XML lv_shared_str_xml.
CALL TRANSFORMATION zben_xlsx_sheet_import
PARAMETERS p_shared_string = lo_shared_str_nodeset
SOURCE XML mv_sheet_data
RESULT lt_spfli = mt_spfli.
CATCH cx_xslt_exception.

ENDTRY.

The internal table mt_spfli is the final internal table needs to be passed to the ALV.
Transformation Parameters Remarks
ZBEN_SHARED_STRING_DEL_NAMESP Source  Shared String Removes the namespace of
XML “Shared String XML”. [we are
going to pass this XML as a
Result  Shared String
parameter string to the main
XML without namespaces
xslt as passing the XML as a
parameter is forbidden]
ZBEN_XLSX_SHEET_IMPORT Source  Sheet XML Processes the sheet data and
shared string data to populate
Parameter  Shared
an ABAP internal table.
String XML without
namespace)
Result (LT_SPFLI) 
ABAP Internal Table

Business Scenario
I have identified two scenarios one for SAP GUI and other for Webdynpro ABAP just to motivate you try out
this unified approach. You could use the same transformation for both the scenarios. Refer the subsequent
sections and try to make out the working scenario by referring to the code snippet showcased in the previous
sections. If you find any difficulties, please go through the complete code (ABAP and XSLT in the last
section)

Scenario 1 – Using SAP GUI
ALV needs to be populated by uploading the data from XLSX document.
Step 1: Choose the XLSX file in the selection screen

Figure 5: Selection Screen captured from SAP GUI with a single parameter for uploading the excel file

Step 2: On hitting F8, the uplaoded excel file needs to be processed and display the data in the ALV as
shown below,

Figure 6: ALV which lists the Flight information which has been processed by our classes and transformation.

Scenario 2 – Using Webdynpro ABAP
Table needs to be loaded by uploading the data from XLSX document
Step 1: Choose the XLSX file in the upload UI element

Figure 7: Webdynpro application with a “FileUpload” UI element and an button to upload the excel file.

Step 2: Click on “Upload XLSX”, the fine needs to be processed and displayed.

Figure 8: Webdynpro “Table” UI element which shows the uploaded data from the excel file.

XLSX Source File – To Upload

I knew that creating a XLSX document from scratch would take a lot of time. If you feel so get the file from
the DDIC itself in the following way,
1. Transaction Code SE16
2. Table Name: SPFLI
3. Execute
4. Upload the ALV output by exporting the data in XLSX format.
