How it works
Three careful steps
- 1Add a CSV
Choose, drop, paste, or try a synthetic sample. Your CSV stays in your browser.
- 2Choose and order columns
Review the source structure, then select the exact columns to keep.
- 3Download verified output
Prontivo reparses the extracted CSV before making it available to download.
Practical use
Share a smaller, focused CSV
Prepare an import, remove unneeded fields before sharing, or arrange the columns a receiving system expects. This tool only selects and reorders columns; it does not filter rows or alter cell values.
Need another CSV fix?
If the text looks garbled, convert the file to UTF-8 first. If the receiving system needs another separator, change its delimiter after extraction.
FAQ
Common questions
Is my CSV uploaded?
No. Processing and download preparation happen locally in your browser.
Can I change the order of columns?
Yes. Use the Move up and Move down controls to set the output order.
What happens without a header row?
Choose No when asked. Generated labels help with selection but are not inserted into your downloaded data.
Can I use a non-UTF-8 file?
Convert its encoding first with the CSV Encoding Converter, then return here.
