Questions
What JSON format works for CSV conversion?
The tool expects a JSON array of objects, where each object represents a row and object keys become column headers.
How does the converter handle nested JSON objects?
Nested objects are typically flattened or serialized as strings in the CSV output since CSV is a flat format with no support for hierarchical data.
Can I open the CSV output in Excel?
Yes, the generated CSV file can be opened directly in Microsoft Excel, Google Sheets, or any other spreadsheet application.
What happens if JSON objects have different keys?
The converter collects all unique keys across all objects to create the column headers. Objects missing a key will have an empty cell for that column.
Can I download the CSV output as a file?
Yes, copy the CSV output and save it as a .csv file, or use the download button if available. The file can then be opened in any spreadsheet application.
How do I convert JSON to CSV for use in a database import?
Paste your JSON array, convert it to CSV, and use the output file with your database import tool. Most databases accept CSV for bulk data imports.
