I tried using XSSFBEventBasedExcelExtractor class but it reads all of the data in the sheets present.
I have many sheets in Binary excel file and I want to extract one sheet. Is there a way to do that? Other approaches are welcome.

i have data in multiple excel files (numbers). I need to use these data (no need to copy) and perform some calculations in another excel file. Could someone help me with macros to do this?
I'm working on Talend and recently my goal was to parse each sheet of an Excel file to do some different things.
For example, nowadays I'm working on an excel file composed of 4 sheets and I want to replace some values by other values in both sheets. The output file would be the same excel file, composed of its 4 sheets with all the values, including those replaced.
I used tFileExcelWorkbook and tFileExcelSheetList to parse my Excel file, then tFlowIterate to create a global variable (name of sheet) and tReplace to make the search/replace.
But actually I'm stuck.. I really don't know How to make it to create the same excel file, with the same sheets by using that tReplace component.
Do you know what I could do to solve that problem, and more generally how to do to parse sheets of an Excel file ?
Thanks !

Julien,
Easier way to parse/process sheets in an Excel would be to use a tFileInputExcel and in the "Sheet list" define the sheet names/position that needs to be worked on.

Folks,
We have one requirement related to scalability for excel update.
e.g. We have Excel work book with 10 work sheets each is having huge amount of data.
Now what we want to do is replace one of the CELL in one of the sheet with 'NEW VALUE'
But with Apache POI we understood we have to load entire 'Work book' even if we have to modify data in one of the excel sheets. This is consuming huge memory and is not acceptable.
Is there any CELL level read write(immediate flush) facility or API for excel.
An XLSX file is actually a ZIP file containing multiple XML files.
You could extract the contents (but keep the folder structure intact), change only the XML file you want, compress it back, and replace the original.
I have a single Excel containing many sheets as sheet1, sheet2, sheet3, etc. I need to split this Excel into individual CSVs, i.e.
sheet1--->file1.csv
sheet2-->file2.csv
sheet3-->file3.csv
and so
on...
I need to do this either using PERL or UNIX. I also want to know the record count from each of the individually generated CSVs.
Since I am a beginner in Unix, I spent much time in writing the code and it doesn't seem working.
Please give your suggestions. Thanks in advance.
I was facing the same issue, I guess this post (link) should help you.Batch split xls sheets to csv -
This contains a js code which you just have to put inside the folder where you have all the xls files.It will split the sheets into separate csv and name them following this syntax: {file_name}-{worksheet_name}.csv
Hope this helps.
You can either use the csvkit program:
in2csv --write-sheets "-" -f Masterfile.xlsx
which will generate as many files as they are sheets
Masterfile_0.csv Masterfile_1.csv ...
or you can also use the ssconvert tool from the Gnumeric project:
ssconvert -S Masterfile.xlsx split_file.csv
but the naming scheme is less convenient as each file have the sheet number prepended (they need to be renamed):
split_file.csv.0 split_file.csv.1
I have several excel spreadsheets in a folder, where each spreadsheet contains several worksheets. I've written a code which loads a specific worksheet from each spreadsheet into matlab. The worksheet is called 'Bass min'.
files = dir('*.xls');
%read data from excel into matlab
for i=1:length(files);
File_Name{i}=files(i,1).name;%Removes the file names from 'files'
[num{i},txt{i},raw{i}] = xlsread(File_Name{i},'Bass min');
end
Is there a faster way of doing this? As I have many spreadsheets its takes a long time to read. I've heard some people mentioning actxserver as a faster method, but don't know how this would work!
many thanks
You could try reading the files in basic mode, in which case Matlab would read the files directly without going through Excel:
[num{i},txt{i},raw{i}] = xlsread(File_Name{i},'Bass min','','basic');
