Data Table Viewer
View CSV and JSON data in a sortable, filterable table with pagination and export
About this tool
Data Table Viewer takes pasted CSV or JSON and renders it as an interactive table. Paste comma-separated values or a JSON array of objects — the tool auto-detects the format and displays the data with sortable columns, a search filter, and pagination.
Click any column header to sort ascending or descending. Numeric values sort numerically; everything else sorts alphabetically. Use the filter box to narrow rows, and adjust the page size for large datasets. Download the current view as a CSV file at any time.
Example CSV: pasting name,score on one line followed by Ada,98 and Lin,76 produces a 2-row table. The same data as a JSON array produces the same result with keys as column headers.
FAQ
Which formats are supported? ›
CSV (comma, semicolon, tab, or pipe delimited) and JSON arrays of objects. The tool detects JSON automatically when the input starts with [ and falls back to CSV parsing.
How is this different from the CSV Preview tool? ›
CSV Preview is focused exclusively on CSV data with column-type detection and statistics. Data Table Viewer handles both CSV and JSON input in a single unified tool.
How big a dataset can I view? ›
Tens of thousands of rows work fine. Pagination defaults to 25 rows per page to keep the browser responsive. Lower the page size or use the filter for very large files.
Can I edit cells in the table? ›
No — this is a read-only viewer. To transform the data, use the CSV to JSON converter to switch formats, then edit in your preferred tool.
