Question 1

How does JSON to CSV conversion work?

Accepted Answer

Diakrio parses your JSON file and extracts records (objects or array elements). Each record is flattened into a CSV row with consistent columns. Nested objects can be flattened with dot notation (e.g., "user.name"), or you can customize the transformation.

Question 2

Can I convert nested JSON to CSV?

Accepted Answer

Yes. Diakrio can flatten nested JSON objects and arrays. Nested properties are converted using configurable strategies: dot notation (user.email), underscore notation (user_email), or you can define custom column mappings in the transform editor.

Question 3

What if my JSON file is very large?

Accepted Answer

The file is parsed incrementally and CSV bytes are emitted progressively. Supported browsers write those bytes directly to disk; other browsers use a bounded fallback. Live telemetry reports measured throughput and resource use.

Question 4

Are CSV headers automatically generated?

Accepted Answer

Yes. Diakrio analyzes the JSON structure and automatically generates CSV column headers based on the detected fields. You can also preview the schema and customize field names before converting.

Question 5

Is CSV the best format for my JSON data?

Accepted Answer

CSV is ideal for tabular data, spreadsheets (Excel, Google Sheets), and database imports. If your JSON contains complex nested structures or you need to preserve exact data types, consider using NDJSON instead for streaming line-delimited JSON.
