And we are live!

Yeah. JsonExport.com is live and ready for would-be users.
And yes, it's also live on the Product Hunt page starting today.
Let's see what we can do collectively, shall we?

First Timer on the Product Hunt Scene! happy to connect.

Hi everyone. How are we doing today?
I am John. I recently joined Product Hunt, and I would like to connect.
I have eyes to see that the community is active and full of life. Definitely where I want to be.
I trust I'm in good hands. Or is it "...nay"?
Lol

Don't be an AI wrapper

Hi everyone, I'm Dario. I have created a platform that allows you to train and deploy in production an AI model trained with your own data.

The idea behind it is simple: AI shouldn't be just a third-party API that we all connect to. Instead, it should be a technology we own and can improve ourselves.

Handling large, sensitive JSON files fully in the browser. What edge cases should I watch for?

I m building JsonExport, a JSON to Excel/CSV converter that runs entirely in the browser.

The main motivation was privacy and scale. I kept running into tools that required uploading sensitive logs or customer data, or that completely fell apart once nested JSON or larger files were involved.

I decided to go fully client-side using streaming parsers and Web Workers, which has worked surprisingly well so far, even with very large files.

I m curious. For those of you who work with messy or sensitive JSON:

JsonExport - Convert JSON files to Excel instantly. 100% Client-side.

JsonExport is a professional JSON to Excel/CSV converter that runs fully in your browser. Most tools are slow, insecure, and fail on nested data. JsonExport handles real-world JSON with privacy-first local processing, smart flattening that removes [object Object], and streaming support for 100MB+ files. It includes a simple editor and a data grid to preview before export. Free to use and open source.

Dos and don'ts before the Product Hunt launch

It s almost here for me. In three days, I ll be relaunching a major update for the app I have been collaborating with, and I ve set clear boundaries for myself about what I will and won t do before the launch. I guess these are some general, unwritten rules I try to follow

Definitely DON T:

  • Accept offers from charlatans promising votes or engagement for money

  • Send unsolicited messages begging for votes or support

  • Spam other people s posts with launch announcements

What's the best AI model for coding?

New AI models pop up every week. Some developer tools like @Cursor, @Zed, and @Kilo Code let you choose between different models, while more opinionated products like @Amp and @Tonkotsu default to 1 model.

Curious what the community recommends for coding tasks? Any preferences?
