json_filter
Extract specific fields from JSON data by defining a shape object. Input a file path (local or URL) and specify desired fields or nested structures to filter results efficiently.
Instructions
Filter JSON data using a shape object to extract only the fields you want. Provide filePath (local file or HTTP/HTTPS URL) and shape parameters.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| chunkIndex | No | Index of chunk to retrieve (0-based). If filtered data exceeds 400KB, it will be automatically chunked. Defaults to 0 if not specified. | |
| filePath | Yes | Path to the JSON file (local) or HTTP/HTTPS URL to filter | |
| shape | No | Shape object (formatted as valid JSON) defining what fields to extract. Use 'true' to include a field, or nested objects for deep extraction. Examples: 1. Extract single field: {"type": true} 2. Extract multiple fields: {"type": true, "version": true, "source": true} 3. Extract nested fields: {"appState": {"gridSize": true, "viewBackgroundColor": true}} 4. Extract from arrays: {"elements": {"type": true, "x": true, "y": true}} - applies to each array item 5. Complex nested extraction: { "type": true, "version": true, "appState": { "gridSize": true, "viewBackgroundColor": true }, "elements": { "type": true, "text": true, "x": true, "y": true, "boundElements": { "type": true, "id": true } } } Note: - Arrays are automatically handled - the shape is applied to each item in the array. - Use json_schema tool to analyse the JSON file schema before using this tool. - Use json_dry_run tool to get a size breakdown of your desired json shape before using this tool. |
