Google Sheets add-on to compare text, fuzzy-match, highlight duplicates▲80
I created an add-on for Google Sheets called Flookup, and it comes both as a free version and a VERY AFFORDABLE paid version. At its core, Flookup is a fuzzy matching add-on that helps you manage text that is less than a 100% match. Beyond that it can be used to: 1. Search for and match data regardless of whether it contains typos. 2. Highlight and delete duplicates duplicates even if the data has mismatched text. 3.

Comparelists.org – Instantly Compare Two Lists, Find Differences▲10
Hey HN, I got tired of manually comparing two lists (think: emails, product SKUs, code, whatever) and built CompareLists.org to make it painless. You just paste your two lists, hit compare, and instantly see what’s unique to each list, what matches, and any duplicates. It handles thousands of lines, works right in your browser (no data leaves your device), and you can export results as CSV/TXT/JSON. There are options for case sensitivity, whitespace, and more. It’s free and there’s no signup. I’d love for you to try it out and let me know what you think—or if there’s a feature you…
