Create a sample JSON document from a JSON Schema Tool

Posted: July 20, 2023  |  Categories: Tools

In our Integration projects, especially nowadays on Azure Integration Services, we often work with JSON messages. And despite Logic App Designer allowing us to generate a JSON schema based on a JSON payload (or JSON message), but there are many situations we need the opposite! We want to generate a dummy message from the JSON Schema in order to test our Logic Apps solutions or now our Data Mapper maps.

Unfortunately, there aren’t any out-of-the-box capabilities inside Logic Apps or the new Data Mapper to generate a dummy message.

I’m doing a lot of demos and sessions on the new Data Mapper, and you cannot imagine the times I forget what the input message for each specific map is, and I find myself always looking for that information.

In order to accomplish that, we normally use free online tools like this one:, but what annoys me about these online tools is that all data are stored in their log files, and sometimes for privacy/security concerns that can be a problem. Mainly because of this reason, I decide, along with my team to start creating these free tools with the source code available on GitHub in order to not raise the same suspicions.
