- **Category:** Development

- **Keywords:** lodash, javascript, json, array, object, utility

## Overview

Use JSON input and a JSON argument array with a fixed Lodash allowlist; arbitrary JavaScript is never evaluated.

## Inputs

- **Input JSON** (textarea): \[{"name":"Ada"},{"name":"Grace"}\]
- **Lodash Method** (select)
- **Arguments JSON** (textarea): \[2\] or \["user.name", "Guest"\]

## When to use

- Split, filter, deduplicate, flatten, or compare JSON arrays.
- Read, check, select, group, or reorder values in JSON objects and collections.
- Convert strings between camelCase, kebab-case, and Start Case formats.

## How it works

- Paste a valid JSON value into the Input JSON field.
- Select a Lodash method from the available allowlist.
- Enter method arguments as a JSON array, such as \[2\] or \["user.name", "Guest"\].
- Run the utility and inspect the JSON result, including the selected method and its output.

## Use cases

- Prepare JSON arrays by splitting values into groups, removing duplicates, compacting entries, or flattening nested arrays.
- Inspect and reshape JSON objects by reading nested properties, checking paths, or selecting and omitting fields.
- Standardize labels and organize collections with case conversion, grouping, and ordering methods.

## Frequently asked questions

### What input does the Lodash Online Utility accept?

It accepts JSON input, including arrays, objects, strings, and other valid JSON values.

### How do I provide Lodash method arguments?

Enter the arguments as a JSON array in the Arguments JSON field.

### Which Lodash methods are available?

Available methods include chunk, compact, uniq, flatten, difference, get, has, pick, omit, groupBy, orderBy, camelCase, kebabCase, and startCase.

### Can it execute arbitrary JavaScript?

No. The utility uses a fixed, curated Lodash allowlist and does not evaluate arbitrary JavaScript.

### What format is the result?

The result is returned as JSON.
