It has two run modes. 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. Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md. ## 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. Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run. For examples already wired to this Actor's own input schema, see the [API](#api) section below. Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`). # README ## JSON to CSV Converter Convert any JSON data into a CSV file effortlessly with this powerful Apify actor. Handle complex nested structures and expand lists into rows with ease. ### Features - **Handles Nested Structures**: Flattens nested JSON objects and arrays into a CSV format. - **Expand Lists into Rows**: Option to expand lists so that each item becomes a separate row. - **Multiple Input Methods**: Provide JSON data via URL or by pasting the JSON text directly. - **Customizable Output**: Define custom separators for nested keys. ### Benefits - **Ease of Use**: Convert complex JSON data without writing any code. - **Flexibility**: Suitable for any JSON structure, no matter how deeply nested. - **Efficiency**: Quickly transform data for analysis, reporting, or integration with other tools. ### How to Use 1. **Input Your JSON Data**: - **JSON File URL**: Enter the URL of your JSON file. - **Paste JSON Text**: Copy and paste your JSON content into the provided text area. 2. **Customize Options** (optional): - **Expand Lists into Rows**: Check this option to expand lists into multiple rows. - **Key Separator**: Set a custom separator for nested keys (default is `.`). 3. **Run the Actor**: - Click the **Start** button to begin the conversion process. 4. **Retrieve Your CSV File**: - After the run completes, download the CSV file from the **Key-value store**. Or export it to another format as per desire. ### Example **Input JSON**: ```json { "id": 1, "name": "John Doe", "emails": ["john@example.com", "jdoe@example.com"], "address": { "street": "123 Main St", "city": "Anytown" } } ``` **Output CSV**: | id | name | emails\[0] | emails\[1] | address.street | address.city | |----|----------|--------------------|--------------------|----------------|--------------| | 1 | John Doe | john@example.com | jdoe@example.com | 123 Main St | Anytown | ### Support For any questions or issues, please open an issue in the GitHub repository or contact support. *** Unlock the full potential of your JSON data by converting it into a CSV format that's ready for analysis and reporting.
