It also supports plotting charts in bar, line, and area formats, horizontally, vertically, in grouped or stacked formats. Multiple series can be plotted at once, and any data series can be easily turned on or off. Additionally, it supports setting titles and saving charts as images.

Backstory: I set out to develop something else but got sidetracked and somehow ended up building this. Because this wasn't planned, development happened haphazardly based on users' and my own needs, which has resulted in some unique features that don't really belong in a CSV viewer. For example, I was experimenting with themes and ended up adding them to the tool, so now you can view CSV data with multiple different color themes and adjust borders! Not sure who would want that, though. Similarly, there is support for importing data from Google Sheets because a user wanted it.

Try it out and let me know if you like it or have any suggestions for improving it. No account is needed and it works locally without server after first loading.
