iferror

utility

Returns fallback if value causes an error

Syntax

iferror(value, fallback)

value (any)

The expression to evaluate

fallback (any)

Value returned if the expression errors

any

Either the value or the fallback depending on whether an error occurs

Convert to number, use 0 if fails

Input:

iferror(.field | tonumber, 0)

Output:

Parse JSON, use empty object if fails

Input:

.config | iferror(fromjson, {})

Output:

{}

The iferror() function safely evaluates an expression and returns a fallback value if an error occurs.

Use iferror() to handle potential errors gracefully in data processing, such as failed type conversions or invalid operations.
