XLSX is a file type used by Microsoft Excel for spreadsheet documents. It is a proprietary format and is part of the Office Open XML (OOXML) specification. XLSX files are based on the Open XML standard, which is an open standard for document exchange. XLSX files can be opened and edited with Microsoft Excel, LibreOffice Calc, Apache OpenOffice Calc, and other spreadsheet programs.
XLSX files can be converted to other formats using software such as LibreOffice Calc, Apache OpenOffice Calc, and Microsoft Excel. These programs can convert XLSX files to other formats such as CSV, HTML, PDF, and XML.
When converting XLSX files, there are several important considerations to keep in mind. For example, formatting and formulas may not be preserved when converting to other formats. Additionally, some of the software used to convert XLSX files may have limited support for certain features, such as macros and pivot tables.
Using XLSX files can also have some drawbacks. For example, XLSX files are not compatible with all versions of Microsoft Excel, and may not be supported by some spreadsheet programs. Additionally, XLSX files are not suitable for use on the web, as they cannot be opened in a web browser.
For these reasons, it is recommended to use a free and easy online website such as Convert.Guru to convert XLSX files.
