CSV\EXCEL FILE READING

[Former Member]

Hi Guys!!

I have designed an upload program.

How to read excel or CSV File from Desktop.

Thanks,

Just upload the file into a suitable structure using cl_gui_upload and then process as an internal table. There aren't any "canned excel upload file" function modules or classes available unfortunately.

Note you'll have to define the delimiters as something in your structure

such as

begin of upload
            col1   whatever
            csv1(1)   whatever it's hex value is

*etc

Note also that if you use EXCEL 2007 it's actually easier since if you use the new xlsx format this is a compressed (zio) open source xml formatted type file which is far more compatable with other systems (including Open Office) than the older proprietary xls format. (Has Microsoft suddenly realized there ARE other systems and file formats out there !).

For more info on EXCEL file formats suggest you read the following WIKI link

http://en.wikipedia.org/wiki/Microsoft_Excel

hi anee,

try out this function module (SE37):

FILE_READ_AND_CONVERT_SAP_DATA

moreover some methods of this class could be helpful:

CL_GUI_FRONTEND_SERVICES

Hi there

have you ACTUALLY tried this yet.

In theory you can convert an XML file (EXCEL 2007 format) but this certainly won't work for a version of EXCEL prior to 2007 - especially since the.xls format is proprietary.

XLSX/SLSM format possibly could work but other formats certainly won't.

The only chance you really have is to convert the speradsheet to a text csv delimited file first and then do the SAP upload.

hi again,

my understanding of anees question was that CSV fit's the needs but

anee don't know how to get the content of the file to the ABAP program.

to solve this problem

FILE_READ_AND_CONVERT_SAP_DATA

should work fine.

Hello Anee

A useful function module for reading .csv files is TEXT_CONVERT_CSV_TO_SAP. The function group containing this fm contains several other function modules which are quite useful.
