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.

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.
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.
I am trying to write a script that will allow me to download numerous (1000s) of data files from a data server (e.g, http://hydro1.sci.gsfc.nasa.gov/thredds/catalog/GLDAS_NOAH10SUBP_3H/2011/345/). Unfortunately, the names of the files in each directory are not formatted in a similar way (the time that they were created were appended to the end of the file name). I need to be able to specify the file name to subset the data (I have a special tool for these data types) and download it. I cannot find a function in matlab that will extract the file names.
I have looked at URLREAD, but it downloads everything including html code.
Thanks for your help!
You can easily parse the link.
x=urlread(url)
links=regexp(x,'<a href=''([^>]+)''>','tokens')
Reads every link, you have to filter all unwanted links.
For example this gets all grb files:
a=regexp(x,'<a href=''([^>]+.grb)''>','tokens')
I want to automate Excel using Perl to do the following task(s):
For a list of Excel .xls files, do the following:
Open the file
Set Format to CSV
Save the file under the original filename and directory, but replace the extension "xls" with "csv"
Close the file
End
I found how to open files, even how to save them. I did not find how to change the fileformat/save as a different format. There shall be no user dialogs popping up, it should be fully automated. The Excel file list I can generate myself, a parameterized "find" or maybe "dir" should suffice.
If you are using Excel automation a great help is Excel itself. Use the VBA environment (Alt+F11) to get help for the Excel objects you want to use.
The objectbrowser (F2) is very valuable.
Workbook.SaveAs([Filename], [FileFormat], [Password], [WriteResPassword], [ReadOnlyRecommended], [CreateBackup], [AccessMode As XlSaveAsAccessMode = xlNoChange], [ConflictResolution], [AddToMru], [TextCodepage], [TextVisualLayout], [Local])
Searching for CSV in the object browser will show Excel constants with their values, since you probably cannot use these Excel constants in Perl.
See Spreadsheet::ParseExcel and xls2csv, they will help you.
An iPhone app which I am creating generates reports from a Core Data database as a CSV file, which can then be emailed so that the user may use that data elsewhere outside of the app. I would also like to offer the ability to generate the same reports as a PDF file (of course, with nicer formatting) allowing the user to immediately print the report rather than having to jump through several hoops as with the CSV file - i.e. open in another application (e.g. Excel, Numbers) then reformat the columns (so they are wide enough for printing), bold the headings, etc.
Essentially, I want to provide the PDF file so that the user is immediately given a nicely formatted report, and they only need to export the CSV file if they wish to do data manipulation and need a format which is editable.
I was thinking that the easiest method would be taking the CSV file and the converting this into a PDF file, which would be the same as the CSV except would incorporate nicer formatting (such as a tabular layout) rather than the simple comma-separated format of the CSV file. I have been unable to find any ready-made classes for this purpose (to avoid reinventing the wheel) and I am unsure how to approach this since I have limited experience with this aspect of the SDK. Any suggestions or pointers in the right direction would be much appreciated.
You have two different problems:
Read CSV data into some structure in memory
Turn some structure in memory into a PDF
Aaron Saunders has posted some links for step 2, so here's a link for step 1:

That's a CSV parser I wrote that will turn your CSV file into an NSArray of NSArrays of NSStrings.
