Files with the .ODS extension contain compressed spreadsheet files, stored in an open format based on XML . The ODS standard, which is an element of the ODF specification for office suite documents, was created on the basis of the OpenOffice.
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 ODS 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 ODS 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 ODS to XLSX does not meet your expectations, you can simply try to find on the Internet a different version of your file in ODS format, properly converted to a XLSX file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file ODS the desired result was not achieved, you can try to change the format of ODS file to other than XLSX. 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 ODS 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 ODS 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.
