Show HN: Tablecraft – instant in-browser table converter/exporter

I needed something simple to convert small tables back and forth between CSV, Markdown, JSON while debugging scripts, writing docs, or answering Slack messages. Nothing quite fit (most tools are either huge Electron apps or too limited/complex), so I built Tablecraft.

1) Paste any of the supported formats (or start empty)

2) Live preview + light editing (tab to navigate cells, create new rows, etc.)

3) One-click export to CSV, Markdown table, JSON (array-of-arrays or header + rows), or PNG (pixel-perfectish)

It’s deliberately minimal and very much an MVP (some rough edges, mobile support is “works but ugly”, missing features). Still deciding whether to open-source it.

Feedback/curses/feature ideas very welcome—especially if you actually find yourself using it.

Tried it and it’s actually pretty useful. Most converters feel heavy or cluttered, so having a quick in-browser tool for small tables is nice.

The live preview and one-click exports work well. PNG export is a cool extra.

A simple header toggle or header detection would be helpful, but it’s already solid for an MVP.

Thanks for trying it out.

By default, tablecraft currently assumes headers for all pasted tables. But I'll probably have to tweak it to also work with headless tables.
