safe-text-to-json

safeJsonParse extracts the first JSON object that appears inside a noisy string and returns that object, or null if there is no valid JSON payload. It is meant for toolchains where untrusted data is interleaved with markup, logging prefixes, or other extraneous content.

Installation

npm install safe-text-to-json

Usage

import safeJsonParse from "safe-text-to-json";

const raw = "prefix {\"id\": 42} suffix";
const result = safeJsonParse<{ id: number }>(raw);

if (result) {
  console.log("parsed id", result.id);
} else {
  console.log("no valid JSON found");
}

The parser only inspects the first { … } pair, so if a string contains multiple JSON fragments the earliest one is returned. Any failure or malformed content yields null instead of throwing.

API

safeJsonParse(text)

• text: string that may contain a JSON object
• Returns the parsed object or null on failure
