    Nope. Use third party stuff, or don't do it.

    You can however play a trick if the requirements really are that simplistic. In stead of using actual excel files, export data to a CSV file in stead and use that. Then all you need basically is regular Reader/Writer classes to manipulate the file. The end result is still the same: you can read & write data "from excel".

    That's not a CSV file. CSV stands for Comma Separated Values. It's not a difficult format to produce, or to read, but you need to get it right. There is no magical 'process' other than just writing the code, but make sure you understand the file format correctly first.

    But thing is the text file treat as entire data is one data,it's not like row wise and column wise.
    we can read the data by stream as whole from file ,but how can get/know EMP data based on EMP id.

    Regarding Secuirty constrains of my project i am not send the Actually Requirement or data.
    Basic requirement is Based Trans ID i need to get Email ID then send the email to Businees people.
    Right now Excel has data for all Trans ID.
    how can acchive this issues the Same Excel data converted in to Text file data.

    Thanks,

    I don't know what that means. An Excel file isn't 'one data', it is in fact one or more spreadsheets, each of which contains rows and columns.
    we can read the data by stream as whole from file ,but how can get/know EMP data based on EMP id.
    It's just a column in a row, just like everything else in the file.

    Nobody has asked for it. I don't see the point of this remark.
    Basic requirement is Based Trans ID i need to get Email ID then send the email to Businees people.

    These statements have no relevance to this forum.

    This question has no ascertainable meaning whatsoever. You've been told you must use CSV. I have no idea what you're asking for now.
