- **Category:** Data Processing

- **Keywords:** array, zip, object, keys, lodash

## Overview

Create an object by pairing keys and values by index.

**Highlights:**
- Uses lodash `_.zipObject`
- Accepts JSON arrays for keys and values
- Missing values default to undefined

**Example:**
- Keys: `["id", "name"]`
- Values: `[1, "Ada"]`
- Result: `{"id": 1, "name": "Ada"}`

## Inputs

- **Keys** (textarea): Enter a JSON array of keys
- **Values** (textarea): Enter a JSON array of values

## When to use

- When you have two parallel arrays of data that need to be combined into a key-value object format.
- When you need to quickly map a list of identifiers to their corresponding data points for API payloads.
- When you are cleaning or restructuring raw data arrays into a more readable JSON object format.

## How it works

- Input your keys as a JSON array in the 'Keys' field.
- Input your corresponding values as a JSON array in the 'Values' field.
- The tool automatically pairs the elements by index to generate the resulting object.
- If the values array is shorter than the keys array, the remaining keys will be assigned an undefined value.

## Use cases

- Converting database column headers and row data into JSON objects.
- Merging configuration keys with their respective setting values.
- Mapping user IDs to user metadata for frontend state management.

## Frequently asked questions

### What happens if the keys and values arrays have different lengths?

If there are more keys than values, the extra keys will be assigned a value of undefined. If there are more values than keys, the extra values are ignored.

### Does this tool support nested objects?

Yes, as long as your input arrays contain valid JSON structures, the tool will pair them into the resulting object.

### Is this tool using a standard library?

Yes, this tool utilizes the lodash _.zipObject function to ensure consistent and reliable object creation.

### What format should the input be in?

The inputs must be valid JSON arrays, such as ["key1", "key2"] and ["value1", "value2"].

### Can I use this for large datasets?

Yes, the tool is designed to handle large arrays efficiently, provided they are formatted as valid JSON.
