Wow, I just mentioned I relaunched SpreadsheetLight, and now it’s free?
Truth be told, it was a hard decision. I spent a lot of time and effort on SpreadsheetLight. There’s an ECMA documentation PDF that’s over 5000 pages long involved. There’s cross-referencing with the Open XML SDK documentation. There’s experimentation with the actual Excel software to make sure the values are correct. I wrote copious amounts of XML documentation (every single public function and property) so that IntelliSense helps the programmer while he’s using the library.
Did you know Excel’s interface takes in values that are different when assigned to certain corresponding properties? SpreadsheetLight functions take in those Excel “approved” values rather than the Open XML recognised ones. Using SpreadsheetLight is as close to using Excel as you can get.
The crucial point came down to this: I want programmers to benefit from the software. It’s of no use to me or any programmer lying forgotten and hidden behind a pay wall.
And so I freed it.
It’s now free, both in gratis and libre. It uses the MIT License. Download it. Do whatever you want. Come back and tell me how easy your life became.
I only ask that you tell anyone who might benefit from the use of a spreadsheet library. Even if you don’t need to create spreadsheets, you can still download it and see how easy it is to create one.
SpreadsheetLight can be found here. Thank you.
