Can I censor only specific nested keys without affecting the rest of the JSON?

Yes, the tool allows you to target keys and values in objects and arrays, so you can redact selective fields while leaving the surrounding structure intact.

What types of data can be censored in the output?

You can censor keys and values in objects, values within arrays, and numbers in numeric data types, with the option to replace them with a custom string.

Is there a limit to the size of JSON I can upload?

The material does not specify size limits, but as a free online tool, very large files may experience slower processing times.

Will the censored JSON still be valid for API use?

The tool preserves the overall format integrity of the original JSON, so the output should remain a valid JSON structure suitable for most API workflows.

About this tool

What Censor JSON Data does

Censor JSON Data is a free online utility that sanitizes JSON documents by removing or replacing specified keys and values. Users upload raw JSON, define which elements need anonymization, and receive a scrubbed output that preserves the original structure. The tool supports redacting keys and values within objects, values in arrays, and numeric data types, allowing users to specify replacement strings for sensitive data before transmission or storage.

Step by step

How to use the Online JSON Tools Censor JSON Data

1
Load your raw JSON into the input field on the Censor JSON Data page
2
In the tool options, select which keys, values in arrays, or numeric types to censor
3
Specify the replacement string you want to use for the sensitive data
4
Process the JSON to generate a sanitized version ready for sharing or storage

Is it right for you

Best for

Developers and data handlers who need to quickly remove personally identifiable information or API keys from JSON datasets before sharing or committing them to version control.

Limitations

Ads appear on the hosting page
Censorship rules are based on pattern matching rather than strict schema validation
Output format depends on the specific replacement strings chosen by the user
