JSON Parser
Online JSON Parser
OnlinePaste a JSON object (or array) as a template, set a count, and click Generate. The tool produces N copies of your template with sequential IDs and realistic name/email values substituted. Useful for generating test fixtures, populating demo UIs, or creating bulk seed data.
Free, fast, runs in your browser. No login needed.
The generator clones your input template N times. After cloning, it applies a small set of substitutions to make each object distinct:
id field, it is set to 1, 2, 3, … for each copy.name field, it becomes "User 1", "User 2", etc.email field, it becomes "[email protected]", "[email protected]", etc.id, name, or email.Not a faker library. This tool does not generate realistic random data for arbitrary fields. It is a template cloner with minimal substitutions. If you need diverse mock data (random addresses, phone numbers, dates), the output is a useful starting point to manually vary or process further.
Count limit. The UI accepts 1–50 objects. For larger datasets, run the generator multiple times or adjust the count field directly.
Only three: id (sequential integer), name ("User N"), and email ("[email protected]"). These substitutions only apply if the field already exists in your template — the generator does not add new fields.
No substitution is applied for that field. All copies will have identical values for fields other than id, name, and email.
The count input is capped at 50 in the UI. For larger batches, you can run the tool multiple times and combine the output arrays, or adjust the count field directly.
No. Generation runs entirely in your browser.
