What is a .XLTX file?
XLTX is a Microsoft Excel template - the same zipped XML package as XLSX, used as the starting point for new workbooks.
- Did you know
- An XLTX is a macro-free Excel template - the reusable starting point for new workbooks, carrying formatting and formulas but no code.
- The x marks it as the XML-based, macro-free format introduced with Office 2007.
- Like XLSX it is a ZIP package, so renaming a .xltx to .zip lets you browse its sheets and styles as XML.
- What Analyser shows you
- Open and read Microsoft Office documents - modern Word, Excel and PowerPoint (DOCX, XLSX, PPTX), their template, macro-enabled and slideshow variants (DOTX, XLTX, POTX, DOCM, XLSM, PPTM, PPSX), the binary Excel workbook (XLSB), and the legacy 97-2003 binaries (DOC, XLS, PPT) - plus the OpenDocument family in every shape: zipped and flat single-XML text, spreadsheets, presentations and graphics (ODT, ODS, ODP, ODG, FODT, FODS), templates (OTT, OTS, OTP, OTG), legacy StarOffice (SXW, SXC, SXD), and EPUB e-books, shown as page previews with selectable text, tables, sheets and slides. Excel workbooks (XLSX and its macro/template variants, plus the binary XLSB) and OpenDocument spreadsheets (ODS) additionally open in a full analysis workbench alongside the sheet preview - a virtualised grid with sort, filter, search and column tools, a group-by summary, and a chart builder - to explore the data itself, not just preview it.
