Is Excellent Data Filler safe?
Excellent Data Filler answers page messages on every site by returning or overwriting its stored spreadsheet rows.
The extension fills web forms from spreadsheet data you store in it. Its content script runs on all sites and all frames and accepts window.postMessage requests (GET-ROWS-FROM-EXCEL, ADD-ROWS-IN-EXCEL) without checking the sender's origin. Any web page can therefore read back your stored rows and form fields or replace them.
