## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## JSON Data Cleaner & Normalizer

Clean, normalize, and de-duplicate JSON records with a simple and predictable workflow.

JSON Data Cleaner & Normalizer processes arrays of JSON objects, removes unnecessary whitespace from string values, optionally converts object keys to lowercase, and removes exact duplicate records.

It is designed for API workflows, ETL pipelines, automation, analytics preparation, and structured dataset cleaning.

### Features

- Trim leading and trailing whitespace from string values
- Optionally convert object keys to lowercase
- Remove exact duplicate records
- Process arrays of JSON objects
- Store clean results in the default Apify dataset
- Deterministic and predictable processing
- No external website access required

### Input

Provide the records you want to process in the `items` array.

#### Example

````json
{
  "items": [
    {
      "Name": " Alice ",
      "City": " Naples "
    },
    {
      "Name": " Alice ",
      "City": " Naples "
    }
  ],
  "lowercaseKeys": true,
  "trimStrings": true
}

# Actor input Schema

## `items` (type: `array`):

Array of JSON objects to normalize.
## `lowercaseKeys` (type: `boolean`):

Convert object keys to lowercase.
## `trimStrings` (type: `boolean`):

Trim leading and trailing whitespace from strings.

## Actor input object example

```json
{
  "items": [],
  "lowercaseKeys": false,
  "trimStrings": true
}
````

# Actor output Schema

## `results` (type: `string`):

Items written to the default dataset.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("urban_souffle/mf-99-data-normalization-for-unified-job-market").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("urban_souffle/mf-99-data-normalization-for-unified-job-market").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call urban_souffle/mf-99-data-normalization-for-unified-job-market --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,urban_souffle/mf-99-data-normalization-for-unified-job-market"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
