Preview CSV export in your browser: first… by AutoAugeo

A preview-only page: the report and the first 20 cleaned rows of a CSV export of transactions. No download, no key field, and its script sends nothing.

Works offline, entirely in your browser: no account, no network calls, no data collected. The extension asks for no permissions; the toolbar button opens the tool in a new tab. Also on the web: https://augeo-csv-cleaner-free-20-row-preview-of-your-adc5.pages.dev/

The tool is free. Some extra materials are sold separately on the website through Gumroad (linked inside the tool); buying them is optional.
