The Format Converter Node can be used to quickly convert data from one format to another.
Using the Format Converter node

JSON input, CSV output - properties available
One property is available if the input format is JSON and the output format is CSV.

Flows
This documentation describes how Flows can be run from REST API, listeners, or they can be scheduled.
- Nodes
  - Maps
    A map node invokes a LNK map within a flow.
  - Flow
    A flow node invokes a sub flow within a flow. Sub-flows need not be wired to other nodes; it is valid to have a flow that is comprised of multiple sub-flows that each have listeners.
  - Source and Target
    Source and Target nodes provide Link with an outside-in approach to developing integrations. The inside-out approach means that you begin with a map, add inputs and outputs, and then configure these to access resources. Connections might be created in the process. The outside-in approach implements the integration from the opposite direction. You begin with the outside interfaces, then connects them to provide maps and other artifacts.
  - Cache Read and Write
    This documentation describes the function and use of the Cache Read and Cache Write nodes.
  - Clone
    The Clone node has one input and two output terminals. This node clones, or copies the input data from the single input terminal to both output terminals.
  - Decision
  - Fail
    Fails the flow execution.
  - Format Converter
    The Format Converter Node can be used to quickly convert data from one format to another.
    - Converting from XML to CSV or Delimited
      When converting from XML to CSV or delimited, the XML elements to convert to CSV are selected by an XPath expression.
    - Using the Format Converter node
      These instructions describe how to use the Format Converter node in a flow.
      - CSV input format - available properties
        These properties are available if the desired input format is CSV
      - CSV input format Delimited - available properties
        These properties are available if the input format is Delimited:
      - CSV output format - available property
        One property is available if the output format is CSV.
      - CSV output format delimited - available properties
        These properties are available if the output format is Delimited:
      - JSON input, CSV output - properties available
        One property is available if the input format is JSON and the output format is CSV.
      - JSON output, CSV input or delimited- properties available
        his property is available if the output format is JSON and the input format is CSV or Delimited:
      - XML input, CSV output or delimited- properties available
        This property is available if the input format is XML and the output format is CSV or delimited:
  - JAVA
    Invokes a java class, performing user defined functionality based on the properties specified for the java class to act on the input.
  - Join
    The Join node gathers the individual results and appends to a single output file or terminal.
  - Log
    This node logs the raw data from the node input into the file and propagates the data from the input to the output terminal.
  - REST Client
    The REST Client flow node provides a simple and powerful way to access REST services. It can be used to directly invoke REST APIs or can use prebuilt configurations that define the APIs of the service. The node supports:
  - Route
    The Route node provides a way to route data conditionally to one or more outputs of the node. The node bases decisions by evaluating a condition for a flow variable and determining whether to send the data to output 1 or 2 or both, based on the result of the condition.
  - Sleep
    This node suspends the execution of the flow for the specified number of milliseconds
  - Split
    A Split node should be used when there is a need to split csv data processing. This might occur when csv data processing becomes excessively time consuming. Such time-consuming behavior might occur when you send big csv data to the flow input terminal or it might become memory intense when complex data validation is being performed. The Split node can be used with these, and with other data processing tasks that can be done in parallel.
- Terminals
- Flow terminals
- Scheduled flows
- Listener
  A Flow that has a Map node as its first node, and uses a File adapter for an input, can enable that node's input to be a Watch.
- Flow audits
  Flow audits are a way to retrieve more verbose information about a flow instance.
- Flow variables
  Flow Variables are process data variables that go along with the flow execution, accessible to all nodes in the flow while it is being executed under flow executor/engine context.

JSON input, CSV output - properties available

One property is available if the input format is JSON and the output format is CSV.

Property available:

Input Array Path - When you convert from JSON to CSV, the incoming JSON must contain an array of JSON objects. This array can either be at the root of the document, or elsewhere in the document. If the entire document is an array of objects, the Input Array Path should not be set. Otherwise, specify the path of the array using dot-notation. For example, if the JSON data is:
```
{
    "data": {
        "id": 1,
        "people": [
            {
                "name": "Fred",
                "sex": "male"
            },
            {
                "name": "Susan",
                "sex": "female"
            }
        ]
    }
}
```

the path is specified as data.people.
