Bulk CPF and CNPJ generator

One screen to build the whole test data set

Seeding a staging environment is rarely “I need one CPF”. It is three hundred users, a hundred companies and a file that goes into the database without manual editing. On the Generate tab you pick between CPF, numeric CNPJ or alphanumeric CNPJ, ask for 1 to 1000 at a time, formatted or as plain characters — and in full test-record mode every row arrives with name, email, phone, postal code, date of birth and CPF, consistent with one another and in the Brazilian format.

It is all computed in your browser: no queue, no daily cap, no sign-up, and no document ever reaches CodeCrush servers.

Three export formats, three destinations

• SQL — ready-to-run INSERT statements with the table name you type. Paste into your database client and run;
• JSON — the natural format for fixtures, API mocks and ORM seeds;
• CSV — for a spreadsheet, a legacy importer or PostgreSQL COPY.

And there is always the Copy button, which puts the whole batch on your clipboard when the destination is a test you are writing right now.

When to use the dedicated pages

This page is the combined version, built for volume. If you want a single document, with the tool already pointed at it and the context that matters, the dedicated pages are more direct:

• CPF generator — includes the issuing-state option and the fiscal region table that explains the 9th digit;
• CNPJ generator — covers the 2026 alphanumeric format, the root/branch/check-digit anatomy and real company lookup in the Receita registry.

True for both: the generated documents are fictional and exist for software testing. Using them for fraud or to sign up for a real service is a crime (articles 171 and 299 of the Brazilian Penal Code). The CNPJ lookup, in turn, reads public Receita Federal data served by BrasilAPI, an open-source project maintained by the Brazilian community.
