How to convert APK to PUB?

After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the XLS file after converting to XLSX may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from XLS to XLSX to be the same, you have to do this carefully and choose the proper application from the list below.

There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting XLS to XLSX does not meet your expectations, you can simply try to find on the Internet a different version of your file in XLS format, properly converted to a XLSX file by someone else. If this fails, use the information provided in the further part of the website.

What can I also do?

Unfortunately, if after performing the two previously described steps (trying to find your XLS file converted by someone else, and the attempt to convert it to XLSX on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the XLS file in its original format (without conversion to XLSX file). Such a solution will be difficult to implement, but it certainly will give the best result.
