What it does
Superintendent.app is a Desktop app that enables you to write SQL on CSV files. No more vlookup. No more 1M row limit on Excel. It is fast and handles large file well (e.g. load 1GB file in 10s).
A SQL spreadsheet desktop app that queries and visualizes CSV files using SQL.
Load it back later, send it to your colleague. Never lose your work. Visualie your results in line charts, bar charts, stacked bar charts, and pie charts. Click on columns and press Ctrl+C to copy. Copy millions of cells or as much as your memory allows. Highlight a part of SQL and see its result when you aren't sure what the SQL entails. Click on multiple columns to sort ASC or DESC. Only one click away for your convenience. Just import CSV. The names and types are automatically handled for you. ¿Una aplicación o producto ha mejorado considerablemente tu trabajo del día a día?

I've built a C# IDE, Runtime, and AppStore inside Excel2023 · querystorm.com · ▲670The project is called QueryStorm.

But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
