Paste a JSON Schema or a plain sample object and get a working HTML form back, with field types inferred automatically and ready to copy.
Detected: plain sample JSON (object).
Parsing and form generation happen locally — nothing you paste is sent anywhere.
Paste a real JSON Schema or just a representative sample object — the parser figures out which one it is.
Text, number, checkbox, select, nested fieldsets and repeatable rows, chosen automatically from your data.
Arrays get a real Add another button, both in the live preview and in the copied HTML.
Paste your JSON, check the preview, then copy the markup.
When the pasted JSON has a top-level "properties" key or a top-level "type" key, it is treated as a JSON Schema and each property's declared type and enum values drive the output. Otherwise the parser treats the JSON as a plain example value and infers a type directly from each value it finds: a string becomes text, a number becomes a number input, and so on. Either path produces the same kind of form, so you can start from whichever is easier to get your hands on.
Plain strings become text inputs and numbers become number inputs, labelled from the property name.
Booleans become checkboxes. A schema property with an enum list becomes a select dropdown of those values.
An object value becomes its own fieldset, with its own properties rendered inside as regular fields.
Arrays of plain values or of objects both become a repeatable block with a working Add another button.
Questions about detection, nesting and the copied markup.
If the pasted JSON is an object with a top-level "properties" key or a top-level "type" key, it is treated as a JSON Schema. Otherwise it is treated as a plain sample value and field types are inferred directly from the JavaScript type of each value.
A nested object becomes its own fieldset with its properties inside. An array of plain values (strings, numbers or booleans) becomes a repeatable row of one input with an Add another button.
It generates one repeatable fieldset shaped like the first object in the array (or the schema's items definition), with an Add another button that clones the whole fieldset for additional entries.
Yes. The copied markup is plain, dependency-free HTML with inline field names, ready to paste into a page. If it uses repeatable rows, a small inline script for the Add another button is included automatically.
No. Parsing, type inference and form generation all happen locally in your browser. Nothing you paste is uploaded or stored remotely.
