JSONPath evaluator

Runs a path expression over a document and shows what it found.

It runs entirely in this browser tab: the documents you paste are never uploaded, and the tool makes no network request while it works. Open your browser's network panel and try it — nothing leaves the page.

Settings

Expression: `$.a.b[0]`, `$..name`, `$.items[?(@.price > 10)]`.
Show: Choices: Where it was found, The values.

How to use it

Paste your text into the box above, or open a file.
Adjust the settings beside it until the result is what you wanted.
Copy the result, or save it as a file. The result updates as you type.

Questions

Is what I paste uploaded anywhere?: No. The whole tool is carried as WebAssembly and runs on your own device. That is the point of the group: the files these tools are for are exactly the ones you would not paste into somebody else's server.
How big a file can it take?: About a megabyte, and it says so rather than truncating quietly. Past that you are handing it a database rather than a document, and the input here is a text area — the editing view is capped at forty thousand characters and says so, though the tool still reads all of what you gave it.
Why does it say it guessed?: Because it did. Which format a document is, which delimiter a table uses and whether the first row is a header are all decided by looking at the text. Each guess is right almost always and each is printed on the result, because a converter that guessed silently and got it wrong would eat a file.
Does it change my numbers?: No. A number keeps the text it was written as, all the way through: `1.0` stays `1.0` and a thirty-digit identifier stays thirty digits. Nothing here is ever a floating-point value, which is why a sorted document differs from the original only where you asked it to.
