Papeleo

Papeleo is a browser extension designed to automate the process of filling out online forms. It addresses the repetitive task of entering data into various web forms by enabling users to organize their information into collections, import data from CSV or Excel files, and create custom mappings for each form. The tool is positioned for individuals and professionals who frequently complete forms on official portals, marketplaces, and other websites where standard browser autofill features may not suffice.

Among its features, Papeleo supports personalized field mapping, allowing users to match their data to any field in a web form, not just basic information like name and address. It is capable of handling non-standard fields and complex forms, including those with chained dropdowns such as province and municipality selectors, which it resolves automatically. Papeleo also includes automatic validation for Spanish identifiers such as NIF, CIF, and IBAN, reducing the risk of transcription errors before submission. The extension enables users to maintain multiple profiles—for example, one per client, product, or family member—and to switch between them with a single click. Data security is emphasized, as all information remains local to the user's browser and is encrypted with AES-256, with no external servers involved.

The platform is intended for a range of users, including professionals like tax advisors, administrative managers, lawyers, and property administrators who handle high volumes of forms, as well as individuals such as parents, expats in Spain, and small business owners. Specific use cases highlighted include bulk submission of tax models, multi-platform product listings, and managing administrative paperwork for families or small businesses.

Papeleo is available as a browser extension and can be installed without requiring a credit card. The service offers a free tier that includes up to three profiles with no time limit. , and it is not affiliated with any official Spanish organizations.
