jEdit - your data, in a grid.
A spreadsheet-style editor for the files developers actually wrangle - CSV, JSON, and YAML - with powerful filters and large-data performance, all on your Mac.
What jEdit does
Open a messy data file and immediately see it as a clean, sortable, filterable table - then edit in place and export to the format you need.
- Spreadsheet-style grid - tabbed documents and a responsive ribbon UI, plus a raw text view when you need it
- CSV, JSON & YAML - import and export with format validation, so malformed data is caught before it bites you
- Powerful filters - advanced text, number, and date criteria with a filter history you can step back through
- Large-data performance - lazy loading, caching, and parallel operations handle very large files without freezing
- Console capture & edit - grab system console output and work with it directly
- AI-assisted edits - optional on-device commands to accelerate repetitive transformations (beta)
- Built for macOS - clipboard tools, indexing, a memory monitor, and comprehensive error handling

Who it's for
Developers
Inspect and fix API payloads, config files, and exports without firing up a heavyweight IDE.
Data wranglers
Filter, sort, and clean tabular data interactively, then export to the exact format downstream tools expect.
Analysts
Open large CSVs that choke a normal spreadsheet app and slice them down to what matters.
