What is XLSX file?

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. Previous versions of MX Excel provide support for the XLSX files only after installing a proper plugin.

An XLSX spreadsheet may comprise of:

  • Data stored in form of tables,
  • Charts,
  • Formulas and functions.

The XLSX is a native format for MS Excel 2007 and newer versions. It is supported also in other spreadsheet programs of various office suites. It does not support macros, in order to provide macros support, the format must be changed, for instance into XLSM, dedicated for spreadsheets enabling macro function support.

Besides the standard spreadsheet programs supporting XLSX files, you can also use applications available online. The main example is Google Spreadsheets. It is an application which easily enables to browse, edit and create files in XLSX format, and what is important – using it is completely free. Microsoft provides also free internet version of its spreadsheet – Microsoft Excel Online.

What else may cause problems?

There can be more reasons which determine that you are not able to open the XLSX file (apart from the lack of the proper application installed).

First - the XLSX file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the XLSX file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the XLSX file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the XLSX file has not been completed and it cannot be opened properly).
