Paste the mess.
Read the structure.

The reverse of stringify. Paste broken JSON, a CSV, or a log file — it reads what your editor won't, fixes what's broken with your say-so, and keeps your text where you put it.

JSON, YAML, XML, CSV, a log file, or something broken. It stays in this tab.

Your text stays

The tree arrives beside what you pasted, when you ask. Nothing is swapped out from under you.

Fixes with your say-so

Dots on the lines, plain sentences, one button. Your text corrected in place, undo right there.

Nothing leaves your browser

Reading, fixing and comparing run in your tab. Open the network panel and watch it stay empty.
themes

Wears your editor's colors.

Follows your system between light and dark. Or pick One Dark, Dracula or Catppuccin — the three most-installed editor themes, matched to the hex.
