Table scanning and inspection
A CSV previewer helps you verify the structure of tabular data before importing it elsewhere. It does not allow manual editing. Instead, it renders the raw text into a readable grid so you can confirm column counts and formatting consistency.
This is especially useful for quickly checking the shape of an export, reviewing files from clients, or inspecting logging snippets without fully opening heavy spreadsheet software.
Delimiter and headers
Data tables are not always comma-separated. Switch the delimiter to semicolon, tab, or pipe if the table appears collapsed into a single column. Auto-detection attempts to find the correct separator automatically based on the first few lines.
Toggle the header row to treat the first line of the file as metadata. Trimming cells removes accidental spaces around values, which is helpful when verifying IDs, emails, or SKUs.
Layout controls
Large CSV files can contain millions of rows. The preview row limit restricts rendering to the top section so the tool stays fast.
You can also restrict the maximum cell width to prevent long URLs or JSON blobs from stretching the table out of view. Enable wrap preview to read those long fields within a narrow viewport, or disable it to scan the horizontal layout strictly.
