A cheap way to do this is to use Angular to generate a <table> and use FileSaver.js to output the table as an .xls file for the user to download. Excel will be able to open the HTML table as a spreadsheet. <div id=”exportable”> <table width=”100%”> <thead> <tr> <th>Name</th> <th>Email</th> <th>DoB</th> </tr> </thead> <tbody> <tr … Read more
I faced the same problem with .net Core application. I added the System.Text.Encoding.CodePages nuget package and registered the encoding provider before ExcelReaderFactory.CreateReader(stream) which resolved the issue. System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance); //open file and returns as Stream using (var stream = File.Open(fileName, FileMode.Open, FileAccess.Read)) { using (var reader = ExcelReaderFactory.CreateReader(stream)) { } }

This returns the first nonblank value of the given range of cells. For your example, the formula is entered in the column with the header “a” A B C D … Read more

Compared to many of the existing packages (e.g. gdata, xlsx, xlsReadWrite) readxl has no external dependencies so it’s easy to install and use on all operating … Read more
Assuming you really mean easiest and are not necessarily looking for a way to do this programmatically, you can do this: Add, if not already there, a row of “column Musicians” to the spreadsheet. That is, if you have data in columns such as: Rory Gallagher Guitar Gerry McAvoy Bass Rod de’Ath Drums Lou Martin … Read more
I highly recommend xlrd for reading .xls files. But there are some limitations(refer to xlrd github page): Warning This library will no longer read anything other than .xls files. For alternatives that read newer file formats, please see http://www.python-excel.org/. The following are also not supported but will safely and reliably be ignored: – Charts, Macros, … Read more

We faced the exact same issue in our co. Our tests output excel workbooks. Binary diff was not an option. So we rolled out our own simple command line tool. Check out the ExcelCompare project. Infact this allows us to automate our tests quite nicely. Patches / Feature requests quite welcome!
