'''TrimSpreadsheet''' is a lightweight open-source JavaScript spreadsheet engine. It let's you work with spreadsheet data right in your web browser. As with all TrimPath components, the '''TrimSpreadsheet''' engine is written as 100% standards-based JavaScript and CSS. Spreadsheets are stored as HTML markup, so it's easy to understand and embed into your own web pages. Merely assign a class of "spreadsheet" to your , and the TrimSpreadsheet engine will do the rest. Anyone familiar with CSS can also easily create their own spreadsheet themes.

  • Bold, italic, underline, left/center/right, etc.
    
• Recalculation Engine Features.
  
  • Automated recalculations (by default).
    
  • API-controllable recalculations, for firing off big recalculations just when you want.
    
  • Cycle detection, so no infinite loops during recalculation.
    
  • The recalculation engine is '''cooperative''', so you can optionally programmatically split a large recalculation into multiple phases. If you expect users to have huge spreadsheets, this can help ensure that the engine does not lock up the browser UI.
    
  • The recalculation engine is a separate sub-component that can be used without the UI component.
    
• Simple
  
  • TrimSpreadsheet follows unobtrusive JavaScript design principles, so a spreadsheet is as simple as an HTML.
    
  • TrimSpreadsheet markup is human readable, highly semantic and search indexer friendly.
    
  • The TrimSpreadsheet engine is smaller than most Excel spreadsheets.
    
• Hypertext Cell Contents.
  
  • HTML fragments are supported in your spreadsheet cells.
    
• Cross-browser.
  
• Configurable.
  
  • Scrollbars, row/column header bars, and formula controls are all controllable thru simple HTML markup.
    
• Cool Only In A Browser
  
  • Only those who've programmed against DHTML/DOM would think this is neat, but regular spreadsheet users will yawn...
    
    • Header Row & Column Bars that (try) to stay put during scrolling.
      
    • Resizable Rows & Columns through mouse dragging.
