CSV Viewer & Filter

How to Use the CSV Viewer & Filter

1. Load your CSV data — Paste CSV data into the textarea, click "Upload File" to select a .csv file from your device, or click "Load Sample" to try with example data. The tool auto-detects the delimiter.
2. Search and filter — Type in the search box to instantly filter rows across all columns. The filter is case-insensitive and matches partial text. A badge shows how many rows match.
3. Sort columns — Click any column header to sort ascending. Click again for descending. A third click removes the sort. Arrow icons indicate the current sort direction.
4. Export results — Click "Export Filtered CSV" to download only the visible (filtered and sorted) rows as a new CSV file. The exported file includes headers and uses the original delimiter.
5. Review stats — The stats bar shows total rows, column count, and the number of matching rows when a filter is active. This helps you quickly understand your dataset.

Understanding CSV Data

Common Use Cases

CSV Viewer Tips

• For very large CSV files, use the search filter to narrow down results before scrolling. The table only renders matching rows, which improves performance.
• If the table looks wrong, your delimiter may be incorrect. The auto-detect feature works well for standard CSV files, but you can check by comparing the column count to what you expect.
• Click a column header twice to sort in descending order — useful for finding the highest or latest values in a dataset.
• The exported CSV preserves quoted fields correctly, so you can safely re-import it into a spreadsheet or database without data corruption.
• After filtering, use the matching count badge to verify your filter is working as expected before exporting.
• If you need to transform CSV data into JSON format, export your filtered results and use CSV to JSON Converter for the conversion.
