Reader.csv: View CSV, JSON, XML as tables

About

Reader.csv gives you clean tables instead of CSV, JSON, or XML. Just click the toolbar icon, drag a file in, open one from disk, or just follow a link on the web, and it renders as a clean, sortable table on the spot. No app to launch, no import, no wait.

From there:
• Sort any column with a click.
• Filter a column down to the rows that matter.
• Click a long cell to expand it; click again to collapse.
• Keep the header row in view as you scroll.
• Reopen a recent file in one click.
• Read it in light or dark mode.
• Save the original table or the exact view you created.

POWER TOOLS

Sorting is type-aware — numbers sort as numbers, dates fall in order, text reads naturally. Number columns take filters like >100 or <=50. Reorder, resize, or hide columns to frame the question you're asking. Then save the current view back out as a fresh file or copy to clipboard — sorted, filtered, and trimmed to exactly what you kept.
