OTS Viewer for Android - Read Spreadsheet Template Files

OTS files are OpenDocument spreadsheet templates, part of the OASIS OpenDocument family. LibreOffice Calc and Apache OpenOffice Calc use them to start new workbooks with prepared column layouts, cell styles and formulas; invoices, timesheets and budget forms are typical contents.

GroupDocs.Viewer Cloud makes those templates readable on Android. Rather than porting a spreadsheet engine to a handset, your app posts the OTS file and receives rendered pages as PNG, JPG, HTML or PDF. Thumbnails, zoom and page navigation are part of the same API, and files carrying a password open as well.

An Android SDK for Java shortens the call to a few lines, with samples in the documentation and installation by Gradle or Maven. Because 180+ formats are covered, the ODS workbooks built from your templates render through identical code.

Check any OTS in the free online viewer first, then open a trial account and experiment in the API Explorer once development starts.
