▶FAQ7 questions
What is Json Query Filter?
An online data processing tool. Input: the raw data or content you need to process. Output: the processed result with one-click copy and download. Used for quick processing tasks in development, work, and study. Everything runs locally in your browser — no data is uploaded.
What formats can I convert between?
CSV, JSON, XML, YAML, TOML, and more. If it is a structured data format, we probably support it.
How large a file can I use?
Up to about 10 MB runs smoothly. Bigger files might work but could slow things down a bit.
Does my data go to a server?
Never. Everything stays in your browser.
How fast is it?
Instant for typical files. Large datasets take a couple seconds at most.
Will I lose data during conversion?
Not between compatible formats. If something cannot map cleanly, we will let you know.
Can I use this on my phone?
Sure. Paste data, import files — works fine on mobile too.
