CSV Viewer
Upload or paste a CSV file and view it as a sortable, searchable table. Supports custom delimiters and character encodings.
Why use a CSV Viewer?
Raw CSV text is hard to read — column misalignment, inconsistent quoting, and missing headers make errors invisible. A CSV viewer renders tabular data into a clear, scrollable table so you can spot data issues, verify column alignment, and review file contents without opening a spreadsheet application. Supports comma, tab, semicolon, and pipe delimiters. Combine with the CSV to JSON converter and JSON formatter in the data tools category.
Instant table render
Paste CSV or upload a file — the data renders as a styled table immediately with alternating row colors for readability.
Multi-delimiter support
Choose comma, tab, semicolon, or pipe as the delimiter to match your file format without any preprocessing.
Row & column count
The tool shows row and column counts at a glance so you can quickly verify you have the expected data shape.
CSV vs TSV vs Excel — format comparison
Choosing the right tabular format depends on your data and the systems consuming it.
| Format | Delimiter | Pros | Cons |
|---|---|---|---|
| CSV | , | Universal support, human-readable, small file size | Commas in data require quoting; no type information |
| TSV | \t (Tab) | Tabs rarely appear in data — less quoting needed | Tab characters can be invisible; less tool support |
| Excel (.xlsx) | Binary | Type preservation, formulas, multiple sheets | Requires Office library to parse; larger file size |
| Semicolon-CSV | ; | Common in European locales where comma is the decimal separator | Non-standard; many parsers assume comma by default |
