Files with the .XLSX extension contain spreadsheets compressed in ZIP format, stored in an open format based on XML – Office Open XML. It was introduced into Microsoft Office suite since its 2007 version, in order to provide higher format portability.
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 XLSX file after converting to WB2 may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from XLSX to WB2 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 XLSX to WB2 does not meet your expectations, you can simply try to find on the Internet a different version of your file in XLSX format, properly converted to a WB2 file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file XLSX the desired result was not achieved, you can try to change the format of XLSX file to other than WB2. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your XLSX file converted by someone else, and the attempt to convert it to WB2 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 XLSX file in its original format (without conversion to WB2 file). Such a solution will be difficult to implement, but it certainly will give the best result.
