Robust and Safe JSON Parsing in n8n
detail.loadingPreview
Effortlessly handle complex and potentially malformed JSON data within your n8n workflows. This solution provides robust parsing capabilities, ensuring your automation processes can reliably ingest and process data.
About This Workflow
Dealing with JSON data in automation can be a challenge, especially when dealing with incomplete, incorrectly formatted, or unexpectedly structured JSON. This n8n workflow snippet introduces a powerful solution to overcome these hurdles. It leverages custom JavaScript code to perform robust and safe JSON parsing, transforming raw input into usable data structures. The workflow is designed to gracefully handle errors, provide context for parsing failures, and fix common JSON malformations, ensuring your data pipelines remain stable and efficient. By pre-processing and validating JSON before it enters your main workflow logic, you significantly reduce the risk of downstream errors and streamline your automation development.
Key Features
- Robust JSON Parsing: Handles various JSON formats and structures.
- Error Handling & Context: Captures detailed error messages with contextual information for easier debugging.
- Invalid Escape Sequence Correction: Fixes common issues with improperly escaped characters.
- Unescaped Quote Handling: Addresses malformed JSON strings containing unescaped double quotes.
- Control Character Escaping: Ensures all control characters within JSON strings are properly escaped.
How To Use
- Add the 'Execute Workflow Trigger' Node: Configure this node to receive your raw JSON data. In the
jsonExampleparameter, provide a sample of the JSON you expect to process. - Add the 'Code' Node: Connect the output of the trigger node to this code node.
- Paste the JavaScript Code: Copy and paste the provided JavaScript code (the
jsCodecontent from the snippet) into thejsCodeparameter of the code node. - Configure Node Settings: Ensure the
modeis set torunOnceForEachItem. - Connect Downstream Nodes: Connect the output of the 'Code' node to your subsequent n8n nodes. The output will be either the parsed JSON object/array or
nullwith an error message if parsing failed.
