CSV Viewer Online

Upload a CSV file and view it as a sortable, formatted table

    Drop a .csv file onto the tool or paste CSV text directly.

  2. 2

    Select delimiter

    Choose the correct delimiter if your file uses semicolons, tabs, or pipes instead of commas.

  3. 3

    Browse the table

    Scroll, sort columns, and inspect your data in the formatted table view.

Perguntas frequentes

Is my data safe?
Yes. All processing happens entirely in your browser. Your data never leaves your device and is never uploaded to any server.
What delimiters are supported?
Comma (,), semicolon (;), tab (\t), and pipe (|) delimiters are supported. Semicolons are common in European CSV exports where commas are used as decimal separators.
Is there a row or file size limit?
No hard limit. The viewer handles files with tens of thousands of rows in most modern browsers. Very large files (100k+ rows) may be slower to render.
Does it handle quoted fields that contain commas?
Yes. CSV fields that contain the delimiter character are typically enclosed in double quotes (per RFC 4180). The parser correctly handles quoted fields with embedded commas, newlines, and escaped quotes.
Can I edit the data in the viewer?
The viewer is read-only. To edit CSV data, use the CSV-to-JSON converter or copy the data into a spreadsheet tool.

Dicas e boas práticas

  • 💡If columns are not aligned correctly, try changing the delimiter from comma to semicolon or tab — common in European exports.
  • 💡Click a column header to sort the table. Click again to reverse the sort order.
  • 💡The row count shown in the header excludes the header row — it reflects the number of data records.
  • 💡For very wide CSV files, scroll horizontally to see all columns. The first column stays pinned for easier navigation.
