Is there any way of reading encrypted xlsx file via OpenXML lib? - openxml

I need to read encrypted xlsx file via OpenXML. Is there any ways to do it ?

You can't read a protected file in OpenXML.
You can identify a protected file with:

Perl parse an .xlsm file without using excel

I have an input .xlsm file from which I have to parse some values.
Currently I am using Win32::OLE which from certain reasons I need to stop using.
Is there a way to parse that file without using EXCEL processes?My searches on google lead me to Spreadsheet::ParseXLSX module and Excel::Writer::XLSX(with some problemes), but I don't know whether they require Excel or not.
Thank you!

Importing data from text file and saving the same in excel

I am trying to read data from text file (which is output given by Tesseract OCR) and save the same in excel file. The problem i am facing here is the text files are in space separated format, and there are multiple files. Now i need to read all the files and save the same in excel sheet.
I am using MATLAB to import and export data. I even thought of using python to convert the files into CSV format so that i can easily import the same in MATLAB and simply excelwrite the same. But no good solution.
Any guidance would be of great help.
thank you
To read a text file in Matlab you can use fscanf or textscan then to export to excel you can use xlswrite that write directly to the excel file.

Softartisan Officewriter does not create excel format with .xlsm extension

I want to create new excel sheet with .xlsm extension by using softartisan dll, however in create method of softartisan does not have xlsm format. It has only .xls and .xlsx formats.
My new excel contains macros hence I need .xlsm format.
Code is as follows
Dim xla As New ExcelApplication
errWb = xla.Create(FileFormat.Xls) ''Or errWb = xla.Create(FileFormat.Xlsx)
I want file in .Xlsm format
If anybody knows please suggest.
OfficeWriter does not support manipulating or creating Excel macros/VBA through the API because of the potential security risks. Creating a new XLSM file that doesn't contain any macros has limited usefulness. Hence the XLS and XLSX are the only file formats that can be created from scratch using OfficeWriter.
OfficeWriter does support manipulating existing XLSM files, but the macros/VBA are not accessible. If you need to create a new report that contains certain macros, we recommend that you create an XLSM file in Excel that contains the macros that you need. Then open and modify that file with ExcelApplication. The XLSM file can event be blank, except for the macros that you need.
Dim xla As ExcelApplication = new ExcelApplication()
Dim wb As Workbook = xla.Open("myStartingTemplate.xlsm")
...
Note: I work for SoftArtisans, makers of OfficeWriter.

Most efficient way to handle xlsx / xls input in spring batch

I have to write a spring batch program which should handle excel input.
Is there an itemreader present for excel files.
Special case: What if I am unsure about the input format of the file. It could be any of xlsx or xls and the program should be able to handle both.
Solution I have in my hand: Read excel using poi or jexcel and write into a dat file which could then be processed using FlatFileItemReader.
Write your own ExcelFileItemReader implementing ResourceAwareItemReaderItemStream interface and use poi/jexcel libraries there.
Don't forget to look at FlatFileItemReader source code.

Create Excel file in iPhone programmatically

I want to create a Excel supported file which contains strings and images programmatically. I tried to create a .csv file, but I am not able to .csv file with both string and image.
There are many possibilities. The easiest way is to create CSV-Files but you have to take care which seperators excel uses. For checking that you should create a spreadsheet in excel and save it as csv and take a look into that file using any text-editor.
Another approach is to use SpreadsheetML and here a link to the msdn XML Spreadsheet Reference
Otherwise just create a simple xlsx-file with excel, unzip that file and take a look into that the unziped files.
