In this guide we will show you how to process Trello JSON files with the enterprise version Flexter and convert it to SQL Server.


Trello is a web-based project management application originally made by Fog Creek Software in 2011, that was spun out to form the basis of a separate company in 2014 and later sold to Atlassian in January 2017.

SQL Server

Microsoft SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network (including the Internet).

Setting up SQL Server

  • First we connect to the server through SSMS

  • Then we create a new Database

  • We name our new DB ‘flexter’

  • Then we go to Secutity under Databases and me make a New Login

  • We select SQL Server authentication and put our Login name and Password. Under ‘Default Database’ we select ‘flexter’

  • Then under ‘User Mapping’ we mark ‘flexter’ and ‘db_owner’ and click OK

  • And now we can start processing the file

Processing Trello JSON file

We will be using the Docker Version of Enterprise Flexter on Localhost.

  • We run docker with the below command and create a container that will be destroyed when we exit it

  • Next we generate the Logical Schema ID

  • We now extract our data to SQL Server

  • And now we can see our data
