How to read data from spreadsheet as a look up table

Hello Can anybody please help me out in this..??
I want to read data from a spreadsheet file as it is a look up table.
I want to create a program which lets the user enter an element which is be found in the data in the spreadsheet file and gives back the number which is to the adjoining column of the element in the spreadsheet file.
Example i have the following data in spreadsheet file:
Range  Count
2              10
4              49
6              60
Etc.
If i enter 2 to search the data in the spreadsheet file, i do expect the program replies back with the answer 10 and so on...
Can anyone please help out...
Thanks in advance...

Why autoindex the output?  You should only have 1 output.  Besides, the Search 1D Array is simpler (no loop needed).

  • How to read columns from spreadsheet?

    I have text based spreadsheet files containing several columns of data (previously collected data written to file by "write to spreadsheet file" function). Each column is separated by a tab character.
    I need to plot each column on a separate waveform chart. I am trying to use the "read data from spreadsheet" function to do this, which I understand reads in the spreadsheet file as a 2D array.
    I cannot figure out how to separate each column from the 2D array which is the output of the "read data from spreadsheet" function. For each column in the spreadsheet, I need a 2D array, the first row of which is a series of numbers (1, 2, 3, 4, 5, 6 etc) representing arbitrary time points, and the second row is the act
    ual data from ONE column of the spreadsheet. I could then wire this 2D array to a waveform chart. I would need a separate 2D array for each column in the spreadsheet.
    Could someone suggest how this can be done? Better yet, is there example code available somewhere that shows how to do it?
    Thanks.

    Array indexing in LabVIEW version 6i can be confusing.
    I include an example code that you can study to see how it is done in your case.
    Basically, you need to disable the row index when using the ArrayIndex function. In earlier versions of LabVIEW this was done by right clicking on the index-input and selecting disable/enable input but with the new version this is no longer needed. Just wire what you have and the other port will be disabled automatically. However, if you are using version 6i, make sure you wire the array to the ArrayIndex first. You should then get a 2D version of the Indexing function automatically. In older versions you had to manually drag it to a bigger dimension. Attached are two files. One data file, data.txt, with three rows and three co
    lumns, and one VI, ColumnIndexing.vi, that reads out a specific column from that text file.
    This example code is compatible with LabVIEW 4.1 and up.
    Hope this helps. /Mikael

    How to read data from a zipped MS Access file?

    RPJ,
    You do not need to use the Close Zip File.vi when you unzip a folder.  This VI is used when you are creating a zip folder.
    As for examples, I found a couple of ActiveX based MS Access examples.  These programs look to be pretty basic.  For more in depth example I would search Microsoft Developers Network

  • How to read data from an internal table into a real table?

    Hello experts,
    I'm relatively new to ABAP and I'm trying to figure out how to read data from an internal table into a table that I created.  I'm trying to use the RRW3_GET_QUERY_VIEW_DATA function module to read data from a multiprovider.  I'm trying to read data from the e_cell_data and e_axis_data tables into a table that I've already created.  Please see code below.
    TABLES MULTITAB.
    DATA:
      query_name TYPE RSZCOMPID,
      s_cubename TYPE RSINFOPROV,
      t_cell_data TYPE RRWS_T_CELL,
      t_axis_data TYPE RRWS_THX_AXIS_DATA,
      t_axis_info TYPE RRWS_THX_AXIS_INFO,
      wa_t_cell_data like line of t_cell_data,
      wa_t_axis_data like line of t_axis_data,
      w_corp_tab like line of t_cell_data.
    s_cubename = 'CORP_MPO1'.
    query_name = 'Z_corp_test'.
        CALL FUNCTION 'RRW3_GET_QUERY_VIEW_DATA'
           EXPORTING
             i_infoprovider           = s_cubename
             i_query                  = query_name
            i_t_parameter            = query_string_tab
           IMPORTING
             e_cell_data              = t_cell_data
             e_axis_data              = t_axis_data
             e_axis_info              = t_axis_info.
    If anyone has any information to help me, I would greatly appreciate it.  Thanks.

    Hi,
    <li>Once you call the function module RRW3_GET_QUERY_VIEW_DATA, lets say data is available in the corresponding tables e_cell_data e_axis_data which you have mentioned.
    <li>Modify your internal table defined for other purpose, with data from e_cell_data e_axis_data like below.
    LOOP AT t_cell_data INTO wa_t_cell_data.
      "Get the required data from t_cell_data.
      MOVE-CORRESPONDING wa_t_cell_data TO it_ur_tab.
      "Modify your internal table wih data
      MODIFY it_ur_tab TRANSPORTING <field1> <field2> <field3>.
    ENDLOOP.
    LOOP AT t_axis_data INTO wa_t_axis_data.
      "Get the required data from t_cell_data.
      MOVE-CORRESPONDING wa_t_axis_data TO it_ur_tab.
      "Modify your internal table wih data
      MODIFY it_ur_tab TRANSPORTING <field1> <field2> <field3>.
    ENDLOOP.

  • Read data from xml files and  populate internal table

    Hi.
    How to read data from xml files into internal tables?
    Can u tell me the classes and methods to read xml data..
    Can u  explain it with a sample program...

    <pre>DATA itab_accontextdir TYPE TABLE OF ACCONTEXTDIR.
    DATA struct_accontextdir LIKE LINE OF itab_accontextdir.
    DATA l_o_error TYPE REF TO cx_root.
    DATA: filename type string ,
                 xmldata type xstring .
    DATA: mr      TYPE REF TO if_mr_api.
    mr = cl_mime_repository_api=>get_api( ).
    mr->get( EXPORTING  i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
                  IMPORTING  e_content = xmldata ).
    WRITE xmldata.
    TRY.
    CALL TRANSFORMATION id
          SOURCE XML xmldata
          RESULT shiva = itab_accontextdir.
      CATCH cx_root INTO l_o_error.
    ENDTRY.
    LOOP AT itab_accontextdir INTO struct_accontextdir.
        WRITE: / struct_accontextdir-context_id,
               struct_accontextdir-context_name,
               struct_accontextdir-context_type.
        NEW-LINE.
        ENDLOOP.</pre>
    <br/>
    Description:   
    In the above code snippet I am storing the data in an xml file(you know xml is used to store and transport data ) called 'xml_accontextdir.xml' that is uploaded into the MIME repository at path 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'.
    The below API is used to read a file in MIME repo and convert it into a string that is stored in ' xmldata'. (This is just a raw data that is got by appending the each line of  xml file).
    mr = cl_mime_repository_api=>get_api( ).
    mr->get( EXPORTING  i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
                  IMPORTING  e_content = xmldata ).
        Once the 'xmldata' string is available we use the tranformation to parse the xml string that we have got from the above API and convert it into the internal table.
    <pre>TRY.
    CALL TRANSFORMATION id
          SOURCE XML xmldata
          RESULT shiva = itab_accontextdir.
      CATCH cx_root INTO l_o_error.
    ENDTRY.</pre>
    Here the trasnsformation 'id ' is used to conververt the source xml 'xmldata' to resulting internal table itab_accontextdir, that have same structure as our xml file 'xml_accontextdir.xml'.  In the RESULT root of the xml file has to be specified. (In my the root is 'shiva'). 
    Things to be taken care:
    One of the major problem that occurs when reading the xml file is 'format not compatible with the internal table' that you are reading into internal table.  Iin order to get rid of this issue use one more tranformation to convert the data from the internal table into the xml file.    
    <pre>TRY.
          CALL TRANSFORMATION id
            SOURCE shiv = t_internal_tab
            RESULT XML xml.
        CATCH cx_root INTO l_o_error.
      ENDTRY.
      WRITE xml.
      NEW-LINE.</pre>
    <br/>
    This is the same transformation that we used above but the differnce is that the SOURCE and RESULT parameters are changed the source is now the internal table and result is *xml *string. Use xml browser that is available with the ABAP workbench to read the xml string displayed with proper indentation. In this way we get the format of xml file to be used that is compatable with the given internal table. 
    Thank you, Hope this will help you!!!

  • How to read data from a file in OSB

    hi guys,
    Recently, I've got a problem with reading file from specific location. I've actually followed this post OSB 11g - Read or Poll File in OSB - Oracle Fusion Middleware Blog, and then
    I know how to read a file. However, it does not as expected. Because, I've found no way to read data from the file. Therefore, no chance to manipulate the data like assigning to a variable, or extracting ....
    Hence, is there any way to read data from file by using proxy service in OSB ??? No Java code ???
    by the way, supposed that there is no way to read data from a file in OSB. So, What purposes will the way in the post above be used for?
    Many thanks in advance
