JSON Stringify node — Grafit Pro

Inputs

Port	Type	Default
InputThe object, array or single value to turn into text. Key order is preserved as it arrived; unconnected gives empty text.	json	—
PrettyOn writes the text across multiple lines with indentation, off packs it onto one line — the compact form to send over TCP or OSC.	bool	`true`
IndentHow many spaces each nesting level is pushed in. Negative values count as 0, and 0 collapses the text to one line even when Pretty is on; 2 or 4 read best.	int	`4`

Outputs

Port	Type
Output	string
Length	int

Overview

JSON Stringify is the inverse of JSON Parse. It takes any structured JSON value — objects, arrays, nested structures — and serializes it into a text string. The output can be compact (single line) or pretty-printed with customizable indentation.

The node respects OrderedJSON key ordering, so objects constructed with JSON Object maintain their key sequence in the output text. Plain dictionaries use sorted key order.

Examples

Pretty-print an object:

Input: {"name": "circle", "radius": 1.5}, Pretty: true, Indent: 4

Output:

{
    "name": "circle",
    "radius": 1.5
}

Compact output:

Input: {"x": 1, "y": 2}, Pretty: true, Indent: 0

Output: {"x":1,"y":2}

Pretty-print disabled:

Input: {"a": [1, 2, 3]}, Pretty: false

Output: {"a":[1,2,3]}

Two-space indent:

Input: {"colors": ["red", "green"]}, Pretty: true, Indent: 2

Output:

{
  "colors": [
    "red",
    "green"
  ]
}

Use Cases

Formatting JSON data for display in a Text As Image node on the output canvas
Preparing JSON payloads for transmission via TCP Client or OSC Sender
Debugging data flow by visualizing structured data as readable text
Exporting structured data to external systems or files

Tips

The Length output is useful for monitoring payload size before network transmission.
Key order is preserved from OrderedJSON sources (JSON Object, JSON Merge). This gives you predictable, reproducible output.
Set Indent to 2 for compact-but-readable output, or 4 for standard formatting.
Special characters in strings (quotes, backslashes, newlines, tabs) are automatically escaped.
Booleans serialize as true/false and null values serialize as null, matching standard JSON conventions.
