Hello! First time posting in HN :)

I created this browser extension a while ago, while I was searching for some CSV data for a personal project:

When I found a file online, I wanted to be able to read through it fast and decide in seconds if this was the file I needed, without having to download the file, open it in Excel (took some time in a slow computer), delete the file, etc.

So with this extension I could format the data nice and fast, and see if it was what I was looking for.

I decided to publish it to Firefox, but quickly forgot about it as I stopped working on that project.

Just last month, I realized that a few users had installed the extension during this time. So I decided to spend some spare time improving it, building a few features I wanted to see if I could make, and adding a polyfill for Chrome.

Great tool! The download link for Firefox goes to the Spanish version of the page.

Oh, you're right! Thank you very much, I already fixed it! Thanks!

I love this product. It is solving a very troublesome problem for me. Sometimes, all I want to do is check if a CSV is worth downloading or not. I also no longer have Excel, and opening it on Numbers takes even longer.

Exactly! That was my feeling when I first created it, I'm glad you found it useful too!
