> ## Agent Instructions
> FalkorDB is a graph database that speaks the Redis protocol. Queries are issued as OpenCypher through the GRAPH.QUERY and GRAPH.RO_QUERY commands, not over Bolt or a SQL connection.
> FalkorDB implements a subset of OpenCypher with proprietary extensions. Do not assume Neo4j-only syntax or procedures are available — check /cypher/cypher-support and /cypher/known-limitations before using a clause.
> FalkorDB is the successor to RedisGraph, but they are separate products. Do not present RedisGraph commands, versions, or limitations as current FalkorDB behavior.
> Use the official clients listed in /getting-started/clients rather than generic Redis or Neo4j drivers, and prefer the language the user is already working in.
> Configuration parameters are set with GRAPH.CONFIG SET or at startup; cite the exact parameter name from /getting-started/configuration rather than inventing one.
> This site covers four products: FalkorDB (core), FalkorDB Cloud, FalkorDB Enterprise, and the GraphRAG SDK. Name which one an answer applies to, since setup and operations differ.

> FLEX JSON functions for serializing values to JSON strings and parsing JSON strings into maps or lists.

FLEX json utilities.

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="What are FLEX JSON functions?">
    FLEX JSON functions provide serialization (value to JSON string) and parsing (JSON string to map or list) utilities for use in Cypher queries.
  </Accordion>

  <Accordion title="How do FLEX JSON functions handle invalid input?">
    They handle errors gracefully — `fromJsonMap` returns an empty map `{}` and `fromJsonList` returns an empty list `[]` on parse failures, without throwing exceptions.
  </Accordion>

  <Accordion title="How do I call a JSON function?">
    Use the namespace `flex.json.<function>()`. For example: `flex.json.toJson({name: 'Alice'})` returns a JSON string.
