Screen readers use th elements to announce the column for each cell, and browsers repeat thead when printing across pages.

No. Everything runs in your browser, which matters when the file holds credentials or customer data.

Local · cells escaped, header semantic

Turns pasted CSV into a proper HTML table with `thead` and `tbody`, every cell escaped, and an optional wrapper that scrolls sideways when the table is wider than its column.

How to use the html table generator

1 Paste your input. The result appears immediately.

2 Pick the operation you want.

3 Copy the result, or save it as a file.

Escaping is the reason to generate rather than hand-write. A cell containing <, & or a quote produces broken markup when pasted straight in, and the failure is silent: the browser recovers, the page renders, and one cell has quietly eaten the rest of the row.

The thead and tbody split is not decoration. A screen reader uses th elements to announce which column a cell belongs to as the user moves through the table, so a table built entirely from td is navigable only by someone who can see it. thead also lets the browser repeat the header when a table breaks across printed pages.

The scrolling wrapper solves the layout problem every wide table has: a table will not shrink below the width of its content, so a wide one pushes the whole page sideways. Wrapping it in a block with overflow-x: auto confines the scroll to the table, which is what this site does with its own article tables.
