Frequently Asked Questions
What CSV formats are supported?
Standard comma-separated values with optional quoted fields. Fields containing commas, newlines, or double quotes should be wrapped in double quotes. The first row is treated as the header row.
How do I reorder columns?
Drag and drop the column chips in the column list. The order of the chips determines the column order in the output CSV. The data preview table updates in real time.
Can I split a column into multiple columns?
Yes. Click "Split Column" and choose the column to split and a delimiter character (such as a space, comma, hyphen, or pipe). The column will be replaced with multiple columns, one for each part.
Is my data uploaded to a server?
No. All CSV processing runs entirely in your browser. Your file and data never leave your device.
