JSON is the format you get when you export from an API by hand, dump a payload from a webhook, or save a config file. The Use JSON file step pulls a JSON document into your Parabola flow and flattens it into a table you can transform like any other dataset.

​
Use JSON file

The Use JSON file step pulls a dataset from a JSON file you upload. Once the data is in your flow, you can join, filter, and reshape it with the rest of Parabola’s transform steps.

​
Configuration

Drag a file onto the canvas or click Click to upload a file.
Use JSON file step with the file upload prompt
After upload, the step opens to its settings page and shows the parsed JSON.

In Advanced Settings, you can skip a number of rows or columns when importing — rows skip top-down, columns skip left-to-right.

Helpful tips

  • Files don’t auto-update. Parabola can’t pull updates from your computer automatically. To pull live JSON on each run, use the Pull from an API step or grab the file from cloud storage.
  • Nested fields flatten by default. Deeply nested JSON gets flattened into columns with dot-notation names. If your downstream logic needs them clean, use a Select columns or Edit columns step to rename them.
  • Storage and security. Uploaded files are stored in an Amazon S3 bucket. All connections use SSL and are encrypted.
