Requested order becomes output order
A source id,name,email can be exported as email,id. This is useful both for dropping columns and adapting to a partner’s expected order.
FREE WEB TOOL
Extract selected columns from pasted CSV.
Keep only the columns you need from a large CSV—for example id,email or sku,price,stock. The order you enter becomes the output column order.
A source id,name,email can be exported as email,id. This is useful both for dropping columns and adapting to a partner’s expected order.
email, Email, and a header with trailing whitespace are different strings. If any requested header is missing, the tool stops instead of silently exporting an incomplete shape.
Entering id,name,id does not clone the ID column. An empty request is also blocked rather than generating a CSV of blank lines.
The tool changes selection and column order only. Row order, duplicate rows, and cell values remain exactly where they were.
Extract customer_id,email for a mailing workflow or sku,price,stock for inventory sync. If the goal is privacy reduction, check the final header row before sharing.
