What problem does this tool solve?
JSON records are not always convenient to analyze in a spreadsheet. This free JSON-to-CSV converter turns suitable arrays of records into a table, while making the limits of a flat format explicit.
Six practical questions answered
How do I turn JSON records into a CSV file?
Paste a JSON array of objects or open a local JSON file. Select the delimiter and convert it into a CSV table.
How can I open JSON data in Excel?
Convert suitable records to CSV, then use Excel’s text import controls to select the delimiter and UTF-8 encoding. Review the inferred column types to avoid changing identifiers or dates.
How are JSON property names turned into CSV columns?
The converter collects the property names across the records and uses them as column headings. A property does not need to occur in every row to receive a column.
How can I convert nested JSON objects to CSV?
Enable optional flattening to represent nested object properties in dot notation, such as address.city. If two paths would produce the same column name, conversion stops with a clear error.
What happens when a JSON record is missing a field?
The corresponding CSV cell is empty. An explicit JSON null is written as null, so it is distinct from a missing property in this output.
How can I export JSON product data for spreadsheet analysis?
Convert the array of product objects to CSV. Import the result into your spreadsheet to review prices, categories, and other fields, checking type conversions before analysis.
Practical example
A company receives a JSON array of product records. It exports a CSV with one column for each relevant field and imports the file into Excel for a pricing and assortment review.
How to use the tool
Paste an array of objects or arrays. Choose delimiter, flattening, and formula protection, then process and download CSV.
Additional use cases
- Review structured product data in a spreadsheet.
- Export nested addresses as dot-separated columns.
- Collect varying record keys into a unified set of columns.
Limits and supported formats
CSV cannot preserve JSON data types. Unsafe numbers and duplicate keys stop export to avoid silent changes.
Frequently asked questions
Can every JSON document be converted to CSV without information loss?
No. CSV has no native representation of nested objects, arrays, or JSON data types. Choose a suitable tabular structure and review the result.
Can I choose the CSV output delimiter?
Yes. Choose comma, semicolon, or tab to match the application that will read the file.
Are special characters escaped correctly in CSV?
Fields are quoted, embedded quotes are doubled, and output uses UTF-8. Choose the matching encoding when importing the file.
Does the converter support nested objects?
Yes. Optional flattening expands object paths into columns. It changes the representation; arrays and unflattened objects are written as JSON text within cells.
Is JSON-to-CSV conversion free?
Yes. It runs locally in the browser without an account or external conversion API.
