1. DOCX (Microsoft Word Document)

DOCX is the standard Microsoft Word document format introduced with Microsoft Office 2007. It is an XML-based file format used to create text documents such as letters, reports, resumes, contracts, and official business documents. DOCX files support advanced formatting features including fonts, styles, tables, images, charts, headers, footers, hyperlinks, and page layouts. They also allow collaboration features like comments, track changes, and cloud sharing through OneDrive. Compared to older DOC files, DOCX files are smaller in size and less prone to corruption. DOCX is widely accepted in business, education, and government sectors due to its compatibility and professional presentation quality. It also supports password protection and document encryption, making it suitable for handling sensitive and confidential information. DOCX files can be opened by Microsoft Word as well as many other word processing applications.

2. XLSX (Microsoft Excel Spreadsheet)

XLSX is the default file format for Microsoft Excel spreadsheets. It is used to store and manage numerical data, calculations, and analysis. XLSX files contain rows and columns of data along with formulas, functions, charts, pivot tables, and conditional formatting. This format is extensively used in accounting, finance, payroll, budgeting, inventory management, and data analysis. XLSX files are XML-based, which improves data integrity, reduces file size, and enhances compatibility. They support advanced features such as data validation and charting tools. XLSX files are widely used in business organizations for decision-making and reporting. They can be opened in Excel and other compatible spreadsheet applications, ensuring flexibility and efficiency in data handling.

3. PPTX (Microsoft PowerPoint Presentation)

PPTX is the standard file format used by Microsoft PowerPoint for creating presentations. It is widely used in business meetings, seminars, training programs, conferences, and academic lectures. PPTX files consist of a series of slides that may include text, images, charts, tables, animations, transitions, audio, and video elements. The XML-based structure of PPTX improves file performance and compatibility across systems. This format supports presenter tools, speaker notes, and collaborative editing. PPTX files are ideal for visually communicating ideas, strategies, and reports. They are compatible with most presentation software, making them easy to share and display on different devices without formatting issues.

4. TXT (Text File)

TXT is a plain text file format that stores data as simple text without any formatting. It is one of the most basic and widely supported file types. TXT files can be opened by almost any operating system or text editor, such as Notepad, TextEdit, or command-line tools. They are commonly used for notes, logs, configuration files, program source code, and simple documentation. TXT files have very small file sizes and are easy to create and edit. Due to the absence of formatting, they ensure maximum compatibility and are ideal for data exchange and storage. However, they do not support images, fonts, or styling, limiting their use in professional document presentation.

5. PDF (Portable Document Format)

PDF stands for Portable Document Format, developed by Adobe Systems. It is used to present documents in a fixed layout that remains consistent across devices and operating systems. PDF files support text, images, graphics, hyperlinks, forms, and digital signatures. They are widely used for e-books, invoices, reports, manuals, and official documents. PDFs preserve formatting and are ideal for printing and sharing. They also support security features such as password protection, encryption, and restricted editing. Because of their reliability and universal compatibility, PDF files are commonly used in business, education, and legal environments for secure document distribution.
