Show HN: CSV ↔ JSON converter and CSV line charts
Hi HN,
I often needed quick ways to convert small datasets while prototyping APIs or exploring data.
Most online tools require uploading files, login and signup, which feels slow and sometimes risky for sensitive data.
So I built a small browser-based toolset that runs entirely on the client side.
Current tools:
- CSV → JSON converter
- JSON → CSV converter
- CSV → Line Chart generator
You can paste data directly and get instant results.
Everything runs in the browser (no file uploads on server).
I'm planning to add more utilities like:
- CSV → multi-line charts
- JSON → charts
- more small data tools
Would love feedback on what data utilities people wish existed but can't easily find.
- creator_07 7mo agoJust tried converting a CSV with ~1k rows and it worked instantly. Nice that everything runs in the browser and require no login. Add excel to chart, excel to csv, excel to json. And try to add more chart options. It will be great if you add this features.
- devnpatel 7mo agoThanks for your Feedback. I will take this feedback into action.
- dipika1979 7mo agoGreat tool for researchers and students. I recommend to add logarithmic line chart option also.
- devnpatel 7mo agoThanks for feedback. I was thinking logarithmic chart because when there is large difference between columns in comparison then the column with low values are not visible properly as they get close to x-axis. Also I am thinking to add scatterplot chart first with linear regression option.
- devnpatel 7mo agoThinking of adding more tools like JSON formatter, CSV to bar chart, csv to scatterplot and CSV to pie chart. Curious which ones people here would find most useful.
- creator_07 7mo agoTry to add scatterplot chart as it is helpful for people working with accuracy related data to find outliers.

- devnpatel 7mo agoNot comment ring. I just shared with few dev friends to get early feedback.
