A small example
JSON is a data format. Object keys and strings use double quotes, and trailing commas are not allowed. Paste the example into the formatter.
Make a deliberate mistake
Remove a closing brace and run the formatter. The parser should reject the document rather than silently repair it. Restore the brace to continue.
Validation has two layers
Parsing checks syntax. Your application must still validate meaning: whether a name is present, an amount is within range and a property has the expected type. Valid JSON does not automatically make an input trustworthy.
Compare safely
Use the JSON comparison tool to compare two versions. The result identifies changed paths. These browser utilities do not upload your input, but avoid pasting secrets into any shared screen or demonstration.
Example input
{
"project": "Example",
"values": [2, 4, 6],
"active": true
}
