What is a .OTS file?
OTS is an OpenDocument spreadsheet template - the same package as ODS, used as the basis for new spreadsheets.
- Did you know
- An OTS is the template form of an OpenDocument spreadsheet, opened in LibreOffice Calc as the starting point for new workbooks.
- It is the same zipped XML as an .ods, just marked as a template so it opens as a fresh, unsaved copy.
- Templates like this carry ready-made formulas, formatting and headings - an invoice or budget skeleton - without the user rebuilding them each time.
- Under the hood a .OTS file is really a ZIP archive - rename it to .zip and you can browse the files inside.
- 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.
- Open a .OTS file
- Drag a .OTS file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
