HTMCell - Online Spreadsheet

Demo Version

What is it

HTMCell is a demo application that brings an(other) online version of a spreadshit program. It is mainly deployed as a demo for our work. However it is going to be continuously developed until it meets a minimum of useful functionality. This would be roughly described as:

  • User data space, each user - a different guest initially - will be assigned a different set of tables.
  • External user validation (probably via your Facebook account).
  • Math formula support - initially basic operations and functions
  • Book support (as a collection of related tables)
  • Formatting of tables, rows, columns and cells at user request
  • Scrollable tables, with volatile data in order to support large tables
  • Import / Export (upload/download) CSV files
  • Import / Export (upload/download) XLS(X) files
  • Limitation to the total cells used by each user. Only the cells filled with a value will be accounted.
