Hello HN!<p>It has been about three years since I launched this current iteration of my Google Sheets add-on called Flookup.<p>I'm a solo developer and, currently, I handle absolutely everything to do with Flookup from writing code, replying support emails and even marketing. It is a lot of work but very satisfying because I get to see, first hand, how helpful it has been to my userbase.<p>Before Flookup was launched, there was only one prominent Google Sheets add-on that could be used for data cleaning (to a certain degree) but, luckily for me, that add-on had left a gap in functionality that I was very glad to fill.<p>To develop Flookup, I had to write a new algorithm from the ground up in order to make it actually useful to my userbase. Originally, this userbase comprised me and a small team in an organisation I was working at. Today, that number has grown to at least 10,000 Daily Active Users from every corner of the world (except Antarctica).<p>What is Flookup? It is an add-on that uses fuzzy matching algorithms to power its data cleaning functions. Flookup's functions allow you to match or merge datasets without worrying about how uniform your data is. You can also highlight and remove duplicates even if the text contains typos, punctuation marks or spelling differences.<p>So, today, I'm inviting you to try it out and let me know what you think... here is the link:<p>> https://www.getflookup.com<p>Your free trial is unlimited.<p>Thank you for your time and I hope you like it!
