01 / Overview

What is a CSV viewer?

A CSV viewer opens comma-separated or tab-separated data as a readable table without changing the source file. Paste text or choose a file, then search every cell, sort columns by text, numbers, or dates, move through bounded pages, and export the filtered view directly in your browser.

How to use

  1. 01
    Add your data

    Paste CSV or TSV text, choose a local file, drag one into the source panel, or load the example.

  2. 02
    Confirm the structure

    Leave delimiter detection on automatic or choose comma, semicolon, tab or pipe, then decide whether the first row contains column names.

  3. 03
    Explore the table

    Search across every cell, select a column heading to sort it, and use pagination to move through large results.

  4. 04
    Take the useful rows

    Copy the current page as tab-separated data or download every filtered, sorted row as a new CSV file.

Who it's for

  • Analysts checking exports for missing values, unexpected columns or date ranges before importing them elsewhere.
  • Developers inspecting fixtures, logs and API exports without opening a spreadsheet application.
  • Operations teams finding customer, order or inventory records in a private local file.
  • Researchers reviewing tab-separated datasets while preserving quoted notes and non-Latin text.

CSV files look simple, but commas inside addresses, line breaks inside notes and doubled quote characters all change how a row must be parsed. This viewer follows those quoting rules, detects comma, semicolon, tab and pipe delimiters, and lets you override the guess when a file uses a different structure.

The viewer keeps your source text intact. Rows with fewer fields are padded in the preview, wider rows get extra columns, and a warning reports the mismatch. Nothing is uploaded, and the table is limited to 5 MB and 50,000 working rows to keep an ordinary browser tab responsive.

FAQ

Is my CSV file uploaded?

No. File reading, delimiter detection, parsing, search, sorting and export all run in your browser. The tool does not send your rows to a conversion service. As with any website, avoid pasting sensitive data if your browser or device is managed by someone you do not trust.

Is this CSV viewer free?

Yes. You can paste or open data, change delimiter and header settings, search rows, sort columns, copy a page and download a filtered view without payment or an account. The practical limits are shown in the widget so the browser stays responsive.

How large a CSV file can I open?

The viewer accepts files up to 5 MB and keeps up to 50,000 data rows in its searchable and sortable working set. If a source contains more rows, the page reports the total and clearly marks the limit. Use a desktop or streaming database tool for much larger files.

Can it open TSV and semicolon-separated files?

Yes. Automatic detection checks comma, semicolon, tab and pipe separators in the first complete record. You can override that result from the delimiter menu. Files ending in .tsv start in tab mode, but you can still choose another delimiter before reopening the table.

Does it handle commas and line breaks inside cells?

Yes. A cell wrapped in double quotes can contain delimiters and line breaks. Two double quotes inside a quoted cell become one literal quote. If a closing quote is missing or followed by invalid text, the viewer preserves your source and shows a specific repair message.

What happens when rows have different numbers of fields?

The viewer keeps every value instead of discarding an inconsistent row. Short rows receive blank preview cells, while wider rows expand the table and receive generated column names when needed. A warning shows how many rows differ from the first record's field count.

How does column sorting work?

A column sorts as numbers only when every nonblank value has a consistent numeric form, and as dates only when every nonblank value uses an ISO-style date or timestamp. Other columns use case-insensitive natural text sorting, so values such as Item 2 appear before Item 10.

Can I save only the matching rows?

Yes. Search first, apply any column sort, then choose Download view to save all matching rows in their current order as UTF-8 CSV. Copy page copies only the visible page as tab-separated text, which pastes cleanly into Excel, Google Sheets and similar grids.
