Do you need to generate Excel spreadsheets on your server on a monthly basis? Do you need to create Excel spreadsheets on your web server on the fly? Do you need to take the data in your database and put it in an Excel spreadsheet for your clients?

And do you want to write source code that does that just as easily as using Excel?

SpreadsheetLight makes it easy for you to create those spreadsheets. You can write code that does most of the common Excel tasks with SpreadsheetLight as easily as using Excel itself (usually with only a handful of lines of code!).

You also get full library source code, so you can quickly create custom functions without waiting for technical support. Or you know, you’re just plain curious (that’s fine too).

SpreadsheetLight comes with perpetual royalty-free licensing, so you don’t have to worry about renewal fees.

Check out the sample source code!

Easy to use

SpreadsheetLight is a spreadsheet software library that’s built on .NET Framework and the Open XML SDK from Microsoft. Simply add the SpreadsheetLight library and the Open XML SDK to your software project and immediately start using it.

There is no crippling of feature sets and you don’t need someone to send you an unlock code. Straightforward adding to your project and continue forward with a minimum of fuss.

Simple to learn

You get extensive documentation of SpreadsheetLight so it’s easy to figure out what to do and how to do them. There’s also a quick-start guide so your programmers can start generating spreadsheets within minutes.

*Technical: Most standard functions of generating spreadsheets can be accessed through one class, so your programmers don’t have to search around the library and waste time.

Lightweight yet powerful

SpreadsheetLight offers you

  • Comprehensive styling abilities from font colours to gradient background fills.
  • Support for named cell styles.
  • Easy rich text formatting within a cell.
  • Support for built-in or custom-created themes.
  • Row/column inserting and deleting, while correctly modifying all your merged cells, formulas, tables and defined names.
  • Freezing and splitting worksheet panes.
  • Extensive post-insertion picture abilities from fills and outlines, to perspective shadows, to 3D rotations.
  • Easily insert tables.
  • Sort cell data by column and by row.
  • Set conditional formatting (data bars, color scales, icon sets and cell highlighting galore!).

Simple licensing

Pay once, use forever. It’s royalty free. You get unlimited developer/site/client/machine licenses. You can use it in a commercial product. You can integrate the included source code in your own projects (subject to the MIT License).

You don’t have to worry about renewing licenses or copyright. Isn’t that a relief?

Simple purchasing process

You pay with your credit card or PayPal (payment information is not stored anywhere on the site). You go to a page to download the software library. You sign up in a form with your email address so you can be notified of updates (this is the only form you’ll ever fill in. Promise!)

That’s it! Send the software library to your programmers. Your coffee’s not even cold yet.

Sample code

Extensive documentation

Not sure if SpreadsheetLight suits your needs? Download the MSDN-style documentation* (right-click and choose the “save as” option if you hit trouble) of all the available classes and functions and enumerations and whatnots. (Did you know the SLDocument class does most of your tasks? This means you don’t need to learn about too many new classes before getting started.)

As you’re writing your code, SpreadsheetLight provides you with extensive documentation on its functions and parameters, so it’s easy for you. The idea is so you don’t have to trawl through tons of documentation if you don’t want to.

* The documentation is in a CHM file. You might have to go to the file properties and choose Unblock under the General tab (in Windows) so you can view it.

Features
