        "content": "# Airtable Hierarchical Record Fetcher\n\n## Description\n\nThis n8n workflow retrieves an Airtable record along with its related child records in a hierarchical structure. It can fetch up to 3 levels of linked records and assembles them into a comprehensive JSON object, making it ideal for complex data relationships and nested record structures.\n\n## Features\n\n- **Multi-level Record Fetching**: Retrieves parent record, linked child records (level 2), and optionally grandchild records (level 3)\n- **Selective Level 3 Fetching**: Only fetches level 3 records for specified linked fields to optimize performance\n- **Rich Text Processing**: Converts Airtable's pseudo-markdown rich text fields to HTML format\n- **Hierarchical JSON Output**: Organizes all data in a structured, nested JSON format\n- **Flexible Configuration**: Customizable depth and field selection per execution\n\n## Input Parameters\n\nThe workflow accepts a JSON array with the following structure:\n\n```json\n[\n  {\n    \"base_id\": \"appN8nPMGoLNuzUbY\",\n    \"table_id\": \"tblLVOwpYIe0fGQ52\", \n    \"record_id\": \"reczMh1Pp5l94HdYf\",\n    \"level_3\": [\n      \"fldRaFra1rLta66cD\",\n      \"fld3FxCaYk8AVaEHt\"\n    ],\n    \"to_html\": true\n  }\n]\n```\n\n### Parameter Details\n\n| Parameter | Type | Required | Description |\n|-----------|------|----------|-------------|\n| `base_id` | string | Yes | Airtable base identifier |\n| `table_id` | string | Yes | Airtable table identifier for the main record |\n| `record_id` | string | Yes | Airtable record identifier to fetch |\n| `level_3` | array | No | Array of field IDs from level 2 records for which to fetch level 3 children |\n| `to_html` | boolean | No | Convert rich text fields from pseudo-markdown to HTML (default: false). This requires `marked` npm package. |\n\n## Output Structure\n\nThe workflow returns a hierarchical JSON object with the following structure:\n\n```json\n{\n   \"id\": \"recXXXXXXX\",\n   \"field_1\": ...,\n   \"field_2\": ...,\n   \"level2_child\": [\n      {\n         \"id\": \"recXXXXXXX\",\n         \"field_a\": ...,\n         \"field_b\": ...,\n         \"level3_child\": [\n            {\n               \"id\": \"recXXXXXXX\",\n               \"field_y\": ...,\n               \"field_z\": ...,\n            },\n            ...\n         ]\n      },\n      ...\n   ]\n}\n```"
