About this Tool
Use this CSV Viewer to turn raw comma-separated data into a readable table without leaving your browser. It is focused on quick inspection: check whether the delimiter was detected correctly, confirm the header row, scan row and column counts, and spot broken quoting or unexpected empty cells before using the file elsewhere. The viewer is read-only by default, making it useful for checking exports, reports, and small datasets without changing the source content.

Frequently Asked Questions
Are my CSV files uploaded to a server?
No. The tool parses, transforms, previews, and exports data locally in your browser without uploading your input.
Which CSV details are supported?
The parser handles configurable delimiters, quote characters, UTF-8 text, optional BOM detection, mixed line endings, headers, and line breaks inside quoted fields.
What file sizes are practical in the browser?
Small and medium tables are the best fit. Very large files can use a lot of memory because parsing, previews, and exported results all live inside the browser tab.
Does the viewer change my CSV?
No. This tool is intended for inspection. Editing should happen in the CSV Editor or Data Table Editor modes.
What happens when rows have different numbers of columns?
The tool reports the mismatch clearly. Depending on the mode, missing cells can be kept empty and extra cells can be shown for review instead of being silently discarded.
