Frequently Asked Questions
What is CSV?
CSV (Comma-Separated Values) is a simple text format for tabular data. Each line is a row, and columns are separated by commas (or other delimiters).
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data format that's easy for humans to read and machines to parse. It uses key-value pairs and arrays.
Why convert CSV to JSON?
JSON is the standard format for web APIs and JavaScript applications. Converting CSV to JSON makes data easier to use in web development.
Why convert JSON to CSV?
CSV is ideal for spreadsheets (Excel, Google Sheets) and databases. Converting JSON to CSV makes data easier to analyze in traditional tools.
What delimiters are supported?
You can use any delimiter: comma (,), semicolon (;), tab, pipe (|), or any character. Just specify it in the delimiter field.
Does it handle nested JSON?
This tool flattens nested JSON objects with dot notation. For example, {"user":{"name":"John"}} becomes a column "user.name".
What about special characters?
Values containing the delimiter or quotes are automatically escaped according to CSV standards using double quotes.
Is there a file size limit?
Since processing happens in your browser, the limit depends on your device's memory. Most files up to 50MB work fine.
Is my data secure?
Yes! All conversion happens locally in your browser. Your data never leaves your device or touches our servers.
Can I use this offline?
Yes! Once the page loads, all conversions work without an internet connection.
