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.

I need to extract the "Content Created" date out of thousands of files, but haven't been able to find a way to do this using PowerShell / other Command Line utility.
Does someone out there know a way to obtain this metadata? If so, please can you advise me. Thanks.
I've looked at various resources online, including this site, but haven't been successful thus far.
Here's a screenshot explaining what I'm trying to do.
I've been unable to find a native powershell cmdlet which does what you want. However, I found this article: Use PowerShell to Find Metadata from Photograph Files and the script it used: get file meta data function.
The article talks about image files, but the function is not specific for image files.
I tested it out on a folder containing a Word and an Excel file and the returned Metadata from the Word file contains the Content Created date. The Excel file does not contain/return that value. This is not unexpected as the Details tab of properties for the Excel file does not contain a Content Created value so it seems to be specific for Word files, and maybe some other file or document types.
Update:
You write that you need to extract this info from thousands of files, but if those files are anything but Word-files you probably won't be able to do that.
As far as I can tell this should work with the file types exposing the type of metadata you want. However, it seems that the ContentCreated property is unique to Word. I tried adding a text file (.txt), Acrobat PDF (.pdf), MS Access (.mdb), Excel (.xlxs) and a Word doc (.docx) file to my test folder and the only one that has/returns that metadata property is the Word file.
You should also be aware that the script seems to return metadata localized, so for me to programatically get the info i wanted I had to pipe the output of the script to Select-Object -Property Name,'Innehåll skapat' (which is the Swedish name for Content created). So if you're running on a non-english system you may need to check what the output looks like before creating your Select-Object statement.

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!
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.

Excel Addin Error #NAME?
I think it is a follow-up query to my earlier reported issue concerning User defined function in Excel.
I am able to use the function in Excel when used Manually, but when I write to an excel file using Matlab using xlswrite, it gives an error #NAME?
I am attaching the screenshots of the both when entered manually and when using the function through Matlab.
Thanks
EDIT :
Thanks a lot. I have stored the VBA function as an Excel addin here :
C:\Users\Administrator\AppData\Roaming\Microsoft\Addins
Here is what I saw about Excel Add-ins not loaded when used in Automation :

I am attaching the small snippet of the code from chi_squared() here :
Function Chi_Squared(act, exp, Optional df)
This is how I write to an excel file in Matlab :
Formula_chisqr={[ '=chi_squared(' 'O2:O22' ',' 'M2:22' ')']};
[status, message] = xlswrite1(ExcelFilename,Formula_chisqr,sheetname, Location_Agg);
I also tried giving the complete path as suggested. But it did not work.
Thanks
You have to specify the workbook where the UDF defined. Even if your function is it your PERSONAL.XLSB file. You don't have to do it only if UDF is defined in the same file where you use it.
For example,
='myFunctions.xlsb'!chi_squired(O2:O21,P2:P21)
If myFunctions.xlsb is not opened you may need to specify full path to the file.
If you want to be able to call UDF in any file without specifying the file name, you need to save the file as Add-in, and then enable it in Options - Add-ins - Manage Add-ins.
Another idea: When you use XLSWRITE provide file name with extension XLSX, like test.xlsx, not just test. By default MATLAB saves files with XLS extention in older format. It looks like when you open such file in newer version of Excel (2007/2010) the compatibility mode does not allow macros or UDFs to run.
When you open the Excel as a COM server, the UDF's and Add-ins are not loaded by default. So, you need to first load the add-ins if you would like to use the add-in your Excel file.
Here is the small code snippet in Matlab which loads the add-ins before opening the Excel file.
Excel = actxserver ('Excel.Application');
Excel.Workbooks.Open('C:\YourAddInFolder\AddInNameWithExtension');
Excel.Workbooks.Item('AddInNameWithExtension').RunAutoMacros(1);
File='C:\YourFileFolder\FileName';
if ~exist(File,'file')
ExcelWorkbook = Excel.Workbooks.Add;
ExcelWorkbook.SaveAs(File,1);
ExcelWorkbook.Close(false);
end
Excel.Workbooks.Open(File);

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.
