About CSV Studio
Column types (number, date, text) are detected from the values, which helps spot a stray letter in a number column. Sort by typing a column name or its number. Big files work; the table shows the first 2,000 rows and exports include every row.
Everything runs in this browser tab: your text is never uploaded or stored, and the result updates as you type. It keeps working offline once the page has loaded.
