Import large Excel sheets?

Friends: success! I saved the file as csv and I could import it without problems. The morale: it is still easier in csv...

As some asked, indeed the Excel file had some columns with extra formatting and non-ascii characters, which must be the source of the problems

Thanks to all Francisco

We're working hard to make XLS and XLSX as robust of an option as CSV, so use whichever format best suits your needs!

Hi Eric, keep your eyes peeled for the next version of Wolfram Language, the bug involving sheets with charts in XLS and XLSX has been solved, among many other important bug fixes.

Hi Sean. I am using 11.3, Windows 10. The error message I get is: Import::fmterr: Cannot import data as XLS format. $Failed

Like Kyle mentioned there are some minor bugs with non-ASCII characters on filepaths and perhaps in the file in XLS in 11.3 (only on Windows) which are absolutely being addressed in the next version.

Remember that increasing Java won't help in 11.3 since XLS/XLSX import no longer uses Java!

Francisco,

I suggest saving the excel spreadsheet as a CSV file and import it into Mathematica from the CSV. Version 11.3 has some big CSV import improvements and there are new options that will handle any data format (ie strings with or without quotes, etc)

Regards

Neil

Hi Neil,

11.3 got some big excel updates as well (it no longer uses Java in 11.3), with even more improvements to come in the next version!

Many thanks Neil. Will try your suggestion and inform if it works.
