JSON is great for APIs; CSV is great for spreadsheets. Here is when and how to bridge them.
When to convert - Sharing data with non-technical teammates - Importing into Excel or Google Sheets - Feeding a pivot table
How (no code) Open the JSON to CSV tool, paste your JSON, and download the table. Arrays of objects become rows; keys become columns.
Common pitfalls - Nested objects flatten to "parent.child" - Mixed key sets leave empty cells - Large files may need chunking
For the reverse, the CSV to JSON tool handles it just as fast.
