XLSX is the XML-based workbook format introduced in Microsoft Excel 2007. It contains worksheets, cell formulas, formatting, and data tables wrapped in an OpenXML zip structure.
XLSM is Microsoft Excel’s macro-enabled spreadsheet format. Fileora safely extracts all worksheet data, tables, and values while stripping automated VBA macros.
XLS is the legacy binary spreadsheet format used by Microsoft Excel from 1997 through 2003, built on OLE2 Compound Document containers.
OpenDocument Spreadsheet is an open, XML-based standard format for tabular workbooks, maintained by OASIS and used natively by LibreOffice Calc.
Comma-Separated Values is the universal text format for tabular data. Each line represents a data record, with fields delimited by commas.
Tab-Separated Values stores structured table data using tab characters instead of commas, eliminating escaping conflicts in text containing commas.
Structured Query Language script file. Fileora generates executable INSERT INTO SQL statements directly from spreadsheet and CSV records.
Excel Binary Workbook encodes workbook data, cell matrices, and formulas into compressed binary segments rather than XML text streams. This architecture dramatically accelerates read and write operations for massive multi-megabyte enterprise datasets.
Excel Template is Microsoft Excel XML-based workbook template format. It encapsulates pre-formatted grid layouts, custom formulas, print boundaries, and corporate styling, ensuring that opening the file creates an unsaved workbook duplicate.
OpenDocument Spreadsheet Template defines reusable workbook layouts in the open OASIS standard. It preserves column formatting, calculation formulas, and chart configurations across LibreOffice Calc and OpenDocument-compatible applications.
Apple Numbers is the proprietary spreadsheet format developed by Apple for macOS and iOS. Rather than adhering to an infinite grid model, Numbers files feature freeform canvases containing multiple independent data tables, charts, and media blocks.
