Smart Form Filler extension interface screenshot.

Smart Form Filler is a lightweight Chrome extension designed to automate the repetitive task of filling out web forms. Its main functionality allows users to define custom input values for form fields based on their label names—either manually or through importing from a CSV file. This makes it especially useful for developers, testers, and researchers who frequently need to populate forms with predefined data sets during testing or data entry workflows.

The interface is minimal and dark-themed, with options to add fields, specify values, and save reusable datasets. Users can define pairs of “Label Name” and “Fill With” values, allowing targeted autofill based on field identifiers like “First Name” or “Email”. The option to expand into “More Options” suggests there are advanced settings available, though they are not shown in the preview. With only 37 users and 1 review at the time of review, it appears to be a newly released or niche tool. No author attribution is visible on the Chrome Web Store listing, so the creator is currently unspecified.
