Common JSON Syntax Traps
The JSON specification (RFC 8259) is much stricter than standard JavaScript object literals.
Trailing commas after the last array item or object property throw syntax errors. Single quotes are prohibited around keys and strings—only double quotes are valid. Additionally, undefined and functions cannot be represented in valid JSON.
Client-Side Parsing for Zero Data Exposure
Never paste production database records or authorization payloads into web formatters that post data to remote servers.
DocSwift JSON Formatter runs JSON.parse() and syntax colorizers in your local browser runtime, guaranteeing total data isolation.
