Description

Clean Values

Remove nulls, empty strings, empty collections, default values, and duplicates from JSON data. Optionally trim whitespace, sort keys, and truncate oversized content. A comprehensive cleanup utility for normalizing messy data.

Operations

Each cleanup operation can be toggled independently. Enable multiple operations to clean data in a single pass.

Remove Null Values

Delete object keys that have null values at any depth.

Remove Empty Strings

Delete object keys that have empty string "" values.

Remove Empty Collections

Delete empty objects {} and empty arrays [].

Remove Default Values

Delete falsy defaults — 0 and false. Useful for stripping placeholder values.

Remove Duplicates

Remove duplicate items in arrays. Compares both primitive values and full objects (deep equality).

Trim Whitespace

Trim leading and trailing whitespace from all string values throughout the document.

Sort Keys

Sort object keys alphabetically at all levels.

Max String Length

Truncate strings longer than a specified character count (0 = no limit).

Max Array Length

Keep only the first N items in arrays (0 = no limit).

Remove Large Blobs

Remove base64 strings and long single-line values larger than 1KB.
