XLSX is a file extension used for Microsoft Excel spreadsheet files that are created using Microsoft Excel 2007 and later versions. It is part of the Office Open XML (OOXML) format, which is an open standard file format for office applications. XLSX files store data in a structured format and can include text, numerical data, formulas, charts, and more.
The Office Open XML format was introduced to replace the older binary file formats used by earlier versions of Microsoft Excel (such as XLS). The XML-based format provides several advantages, including better data recovery, smaller file sizes, and improved compatibility with other software applications.
XLSX files can be opened and edited using Microsoft Excel or various other spreadsheet software that supports the Office Open XML format. Additionally, many modern spreadsheet applications and programming libraries provide support for working with XLSX files.
CSV stands for Comma-Separated Values. It is a plain-text file format commonly used for storing tabular data, such as spreadsheets or databases. In a CSV file, each line represents a row of data, and the values within each row are separated by commas (or other delimiters, such as semicolons or tabs).
