LangChain - Output Parsers

In this code:

output_parser = JsonOutputParser(auto_fix=True)
raw_output = '{"name": "Bob", "age": "twenty"}'
result = output_parser.parse(raw_output)

The age value is a string instead of a number. What will auto-fixing do?

AIt removes the age field from the output

BIt will not change the value type; parsing succeeds

CIt raises a type error during parsing

DIt converts the string 'twenty' to number 20 automatically

Step-by-Step Solution

Solution:

Step 1: Understand auto-fix scope
Auto-fixing corrects format errors, not semantic or type errors.
Step 2: Effect on value types
The string 'twenty' remains a string; parser accepts it as valid JSON.
Final Answer:
It will not change the value type; parsing succeeds -> Option B
Quick Check:
Auto-fix fixes format, not value types [OK]

Quick Trick: Auto-fix fixes format, not data types or values [OK]

Common Mistakes:

Expecting auto-fix to convert string to number
Thinking it raises type errors
Assuming fields get removed
