Dummy Data Generator creates realistic placeholder records for prototypes, spreadsheets, demos, and local testing. It avoids real personal data while giving you structured test rows.
Fields
Yes. The tool is free and runs directly in your browser with no account required.
No. Rows are generated entirely in your browser using JavaScript's random number generator — nothing is sent to a server.
Full name, email, phone number, address, company, date of birth, UUID, IP address, and lorem ipsum text — pick any combination via the field checkboxes.
Between 1 and 100 rows per generation. For larger datasets, generate multiple batches and combine the output.
Yes — names, emails, and addresses are assembled from fixed sample word lists (not real people's data), so the output is fictional and safe to commit to a public repo or use in a screen recording.
JSON (an array of objects) or CSV (with a header row), selectable before generating. Both formats can be copied to the clipboard or downloaded as a file.
UUIDs use the standard v4 random format and are effectively unique. Emails are built from name + random number + domain, which makes duplicates unlikely but not impossible across a large batch.
