File data conversion made easy using ABAP custom utility class zcl_filedata_convert

Posted by -

In the last post, I talked about how to read XLSX files into an internal table and convert internal to XLSX files. In this post, I wanted to share a custom utility class that can make tasks of data conversion as simple as a method call. The class is ZCL_FILEDATA_CONVERT.

Below are a few of the code snippets showing its capabilities.

Let's start with XLSX to the internal table.

REPORT syst-repid.
DATA:
lt_itab TYPE solix_tab,
lt_vbak TYPE STANDARD TABLE OF vbak.
PARAMETER:
p_file TYPE string DEFAULT `C:\Users\user\Desktop\VBAK.XLSX`.
START-OF-SELECTION.
cl_gui_frontend_services=>gui_upload( EXPORTING filename = p_file " Name of file
filetype = 'BIN' " File Type (ASCII, Binary)
CHANGING data_tab = lt_itab " Transfer table for file contents
EXCEPTIONS OTHERS = 1
).
IF sy-subrc <> 0.
RETURN.
ENDIF.
new zcl_filedata_convert( )->xlsx_2_itab( EXPORTING it_solix = lt_itab
IMPORTING et_data = lt_vbak
).
cl_demo_output=>display( lt_vbak ).

It automatically handles date and time fields for you.

Internal table to XLSX

REPORT syst-repid.
PARAMETER:
p_file TYPE string DEFAULT `C:\Users\user\Desktop\VBAK1.XLSX`.
START-OF-SELECTION.
SELECT *
FROM vbak
INTO TABLE @data(lt_vbak)
UP TO 100 ROWS.
IF syst-subrc <> 0.
RETURN.
ENDIF.
DATA(lv_xstring) = NEW zcl_filedata_convert( )->itab_2_xlsx( lt_vbak ).
DATA(t_xtab) = cl_bcs_convert=>xstring_to_solix( iv_xstring = lv_xstring ).
cl_gui_frontend_services=>gui_download( EXPORTING bin_filesize = xstrlen( lv_xstring ) " File length for binary files
filename = p_file " Name of file
filetype = 'BIN' " File type (ASCII, binary ...)
CHANGING data_tab = t_xtab " Transfer table
EXCEPTIONS OTHERS = 1
).
IF sy-subrc <> 0.
RETURN.
ENDIF.

similarly converting data from and to CSV or TSV or special separated file, It handles it all.

Use it as it is or modify it to suit your needs.

As always, hope you like the post and use its information in your day to day work.

ABAP read excel(.XLSX) file to internal table in ABAP using CL_FDT_XL_SPREADSHEET

You are given a requirement to upload data to a custom DB table where the user provides you with the file path of the excel on his PC and the report loads the data from it to the Custom table. For experienced Abapers, the requirement is quite straightforward, except that the user wants to upload an XLSX file. There are not many options to read data from XLSX/XLS file. The TEXT_CONVERT_XLS_TO_SAP  function module is one of them but is a performance killer and uses OLE. In this post, I wanted to showcase How we can read data from the XLSX files using CL_FDT_SPOREADSHEET class. Let's start with uploading the file. Now that we have the file in xstring table, let's pass it to CL_FDT_XL_SPREADSHEET to get its object reference. From the object reference, we can retrieve each worksheet data. The data is returned in the form of an anonymous data object which can be dereferenced into a field symbol and passed to the target internal table. Below is the co...

Many a time you need a report for which the output needs to be an email. SO_NEW_DOCUMENT_SEND_API1 is heavily used to achieve the task but let's explore another way of achieving the same using CL_BCS. This post talks about how to use the CL_BCS library provided by SAP to easily send emails. CL_BCS Library The class serves as the interface from BCS to the applications. The methods of the class cater for the send functions. Using CL_BCS, You can: – Attach files to email – Build the HTML/raw of the body. – Set email’s Senders & Receiver – Send an email, etc. Let's see the steps one by one: Initiating CL_BCS: The first thing you need is to initiate a persistent send request. Creating BCS Document: Create the BCS document object which will be sent with the CL_BCS interface to BCS. In this case the Email.
