What is EXCEL File Format?

Microsoft Excel is a widely used spreadsheet software known for its ability to save and share data in various file formats. The different file formats supported by Excel offer flexibility and compatibility with other software applications.

The default file format in Excel is XLS, while the newer and more efficient XLSX format has gained popularity. XLSX files have advantages such as smaller file sizes, improved data recovery, and better compatibility with other programs.

For simpler data exchange, Excel supports CSV (Comma-Separated Values) and TXT (Plain Text) formats. CSV files use commas to separate data, making them easily readable by different applications. TXT files store plain text data without any formatting.

To preserve formatting and layout when sharing data, Excel allows saving files in the PDF (Portable Document Format) format. PDF files are widely used for publishing Excel data while retaining its visual presentation.

For collaborative projects, Excel offers the ODS (OpenDocument Spreadsheet) format, which is open-source and compatible with various software applications.

DBF (dBASE File) is a less commonly used format in Excel, but it is advantageous for handling large datasets and is compatible with dBASE software.

Excel also supports formats like XLT (Excel Template), XLTX (Excel Open XML Template), XLTM (Excel Macro-Enabled Template), and XML (eXtensible Markup Language) for template usage or data exchange between different software applications.
