Examples

Array of Objects

[{"name":"John","age":30},{"name":"Jane","age":25}]
name,age
John,30
Jane,25

💡 Object keys become CSV headers, values become rows

Handling Commas

[{"name":"Smith, John","city":"New York"}]
"Smith, John","New York"

💡 Values with commas are quoted

Nested Objects

[{"user":{"name":"John"},"age":30}]
Flattened or quoted JSON string (tool-dependent)

💡 Nested objects need special handling

Common Mistakes to Avoid

⚠️

Not handling nested objects

Solution: CSV is flat format. Nested JSON needs flattening: {user: {name:"John"}} → user.name or user_name column. Check tool behavior.

⚠️

Inconsistent object keys

Solution: If objects have different keys: [{"a":1},{"b":2}], CSV may have empty cells. Ensure all objects have same structure.

⚠️

Arrays within objects

Solution: JSON arrays in values: {tags:["a","b"]} can't map to CSV directly. Either join as string or create multiple rows.
