API-Ready JSON Generator from Table Record

[VaishnaviLathkar98]

This custom Flow Designer action converts selected fields from any ServiceNow record into a JSON-formatted string. It’s ideal for API integrations, structured logging, or sharing readable record data with other systems or processes.
The action dynamically extracts field values handling reference, choice, and date/time fields and produces clean, human-readable, API-ready JSON output.

Description:
This Flow Designer Script Action takes a record from any ServiceNow table and converts selected fields into a formatted JSON string. It includes robust error handling and proper formatting for different field types, ensuring the output is clean, reliable, and API-ready.

How it works:

Inputs:

1. tableName (String): Name of the table (e.g., incident)
2. recordSysId (String): Sys ID of the record to convert
3. fields (Array of Strings): List of field names to include in the JSON

Logic:

1. Validates required inputs (tableName, recordSysId, fields)
2. Returns a clear error message and sets issuccess = false if:
3. Inputs are missing
4. Record is not found
5. Field list is empty

Fetches the record and loops through the selected fields:
Skips excluded fields like work_notes and comments

Handles field types intelligently:

1. Reference fields → Uses display value
2. Choice fields → Uses display label
3. Date/time fields → Formats as ISO string
4. All others → Uses raw value
5. Converts the final object into a pretty-printed JSON string

Outputs:

1. jsonstring: The resulting JSON output or error information
2. issuccess: true if successful, false if any error occurred
3. errorMsg: Description of any error (empty if successful)

Notes:

1. This action excludes work_notes and comments to avoid large or formatted content.
2. If an invalid sys_id is passed, it will return a clear "Record not found" error.
3. Built-in error handling prevents flow failure and makes troubleshooting easier.
