ScriptCS makes it easy to write and execute C# code. Once you have ScriptCS installed on your PC, all you need is your favorite text editor.
To install ScriptCS, go to http://scriptcs.net/ and follow the instructions.
This sample scriptcs can be used to export all the cards on a board in comma-delimited (.csv) format. You will need ExportCards.csx, CardModel.csx, and the LeanKit.API.Client.Library assemblies (.dll files). You can compile the LeanKit.API.Client.Library, or you can download the files from the LeanKit Support Wiki. You will also need to modify ExportCards.csx to provide your LeanKit account name, email address, password, and the Board ID to use.
Once you have set everything up correctly, you can run the following from a command prompt to export cards and save to a local file named cards.csv.
scriptcs ExportCards.csx > cards.csv
