Hunting for specific values in a wide CSV with dozens of columns? Large CSV Viewer lets you apply per-column filters (contains, equals, greater than, is empty), hide irrelevant columns, and run a global regex search — all without writing a single line of code.

Key features

  • Per-column filter operators: contains, equals, >, <, is null, is not null
  • Global search across all columns simultaneously
  • Regex search for pattern matching
  • Hide columns you don't need with one click

How it works

  1. Click the column icon. Click the type icon (number, text, or date) next to any column header to open the column filter panel.
  2. Set your filter condition. Choose a filter operator (contains, equals, greater than, is empty, etc.) and enter a value. Results update in real time.
  3. Combine multiple filters. Apply independent filters to as many columns as you need simultaneously. Use the global search bar for cross-column keyword searches.

Frequently asked questions

Can I filter by multiple columns at once?

Yes. You can apply independent filters to as many columns as you like simultaneously. Results update in real time.

What filter operators are available?

Contains, equals (=), greater than (>), less than (<), is empty (NULL), and is not empty. Numeric columns also support greater-than and less-than filters.

Can I filter using a regular expression?

Yes. Enable regex mode in the search bar (the .* button), or use per-column regex filters for pattern-based matching.

Can I hide columns I don't need?

Yes. Open the Columns menu in the toolbar to toggle column visibility. Hidden columns are excluded from export.

Do filters apply to the export?

Yes. When you export as CSV, JSON, or Excel, only the rows matching your active filters are included.
