What is JSON to CSV Converter?
A JSON to CSV converter flattens structured JSON data into a tabular comma-separated format, ready for import into spreadsheets, databases, or reporting tools. It handles nested objects by creating dot-notation column headers.
How to Use
- Paste your JSON array of objects into the input area
- The converter extracts keys as column headers automatically
- Review the CSV preview in a table format
- Download the CSV file or copy it to your clipboard
Frequently Asked Questions
- How are nested JSON objects handled?
- Nested properties are typically flattened with dot notation. For example, {address: {city: 'NY'}} becomes a column named 'address.city'.
- What happens with arrays inside JSON objects?
- Arrays are usually joined into a single string (e.g., comma-separated) or split into multiple columns, depending on the converter's settings.
- Can I choose which fields to include in the CSV?
- Yes, many converters let you select specific keys to export, filtering out unnecessary data before downloading.
