Hi,
I am downloading a excel spreadsheet from a website and then i tried to open it using
ExcelEngine excelEngine = new ExcelEngine();
IApplication application = excelEngine.Excel;
IWorkbook workbook = application.Workbooks.Open(@"C:\test.xls");
However the last line throws an error saying CompoundFileException was unhandled Wrong Signature.
I copy pasted the contents of the original xls file (off the web) into another xls file and the code worked fine.
Please advise.

Hi Aditya,
Thank you for the attachment.
I was able to see the issue with your spreadsheet. But when I analyzed the file, it appears to be a htm file renamed with .xls extension. Essential XlsIO does not provide support to open such files. After I re saved the file as .xls using MS Excel I was able to open it using Essential XlsIO.
Please let me know if you have any questions.

Our requirment is to open and process this file on a server which does not have MS Excel installed. Let me know if you think this can be done with any of your products.

Hi Aditya,
Essential XlsIO does not provide support to open a htm file. As a workaround if you can convert it to any form which is supported by XlsIO, that is as an .csv, .xml, .txt (Tab demilited), then you may open it using XlsIO and process it.
Please let me know if you have any questions.
Regards,
Geetha
