Table Editor
Import a table as CSV, TSV, a Markdown pipe table, or a JSON array of objects (or pick the format manually), then edit it in a spreadsheet-style grid. JSON imports union every key seen across records into the full column set, and nested arrays or objects serialize to compact JSON strings. Click a cell to edit it, hover a row or column to insert or delete, and click a column header to sort with number-aware ordering.
Find and replace runs across all cells with an optional case-sensitive mode and reports how many hits were replaced. Undo and redo (Ctrl/Cmd+Z, Ctrl/Cmd+Shift+Z) keep up to 100 steps, and the first row always stays visible as a frozen header while you scroll.
Export the finished table as an Excel workbook (XLSX), CSV, TSV, Markdown, or JSON records keyed by the header row. Everything runs locally in your browser: files are processed on your device and never uploaded.
Limits: up to 10,000 rows, 256 columns, and 2 MB of pasted input. Multiline cells are supported in CSV imports and exported as <br> in Markdown.
