よくある質問
What is JSON to CSV conversion?
JSON to CSV conversion transforms data structured in JavaScript Object Notation (JSON) format into Comma Separated Values (CSV) format. This makes hierarchical or nested data usable in spreadsheet applications like Excel, Google Sheets, or database systems.
How does the converter handle nested JSON objects?
The converter typically uses a 'flattening' method. This creates column names using dot notation (e.g., 'user.address.city') to represent nested structures within a single CSV row, allowing complex data to fit into a 2D table.
What happens if my JSON contains arrays?
If a field contains an array, the converter can join the values with a delimiter (like a comma or pipe) into a single cell, or create multiple rows for each item in the array while repeating parent data, depending on the selected configuration.
Is my data secure when using this tool?
Yes, this client-side calculator processes your data entirely within your web browser. No information is sent to a server or stored externally, ensuring your sensitive data remains private and on your device.
How do I handle special characters in the CSV output?
Standard CSV formatting wraps fields containing special characters (commas, quotes, newlines) in double quotes. Embedded double quotes are escaped (usually by doubling them) to ensure the file parses correctly in spreadsheet software.
Can I convert large JSON files?
The tool can handle moderately large files, but browser memory limits apply. For extremely large datasets (hundreds of megabytes), a command-line tool or server-side processor is recommended for better performance.
