Show HN: A Better Excel Data API

Andreash - this product is designed specifically for Excel - as an end user, you can pull data from within Excel directly to your spreadsheet (which may already contain models, charts etc.), without having to shuffle around multiple files.

Yes, that's one way to look at it. In practice most people send CSV's now, so it's a simpler, streamlined way to do that.

A big advantage of Voyager over both of those options is the ability to send custom data per-user without building an ad-hoc web UI for it.

This is primarily for analytics and other data companies with non-technical customers. They get requests for data in spreadsheets, and they usually manage that by generating and sending over one-off CSV's.

Voyager is an interface that's easier to use for the devs, and much easier for the end-users.

I'd imagine that the most common use cases will be the ones where people are already using excel, where the python is definitely an improvement over python, the default and only other programming language integrated with excel.

I used it to validate my an algorithm written in python, which was basically a many-step series of matrix multiplications

datanitro basically served as a debugger, letting me 'show my work' at each step in the algorithm, outputting matrices to excel spreadsheets as it ran. Excel provides a pretty good set for validating that the output at each step matched expectations, like conditional formatting where you can color cells based on their value and other math and graphing functionality

I can say for sure that I prefer using python with excel to using VBA, the only other previous option.

A user is someone that you send data to (probably one of your customers or employees).
