How it works

Three steps, no account

1

Paste or drop your CSV

Comma-separated values with a header row works best. You can also upload a .csv file directly.

2

Review the table

Transpose it, delete blank rows, or remove duplicates before you generate output.

3

Pick a format and generate

Choose from 28 output formats, then copy the result or download it as a file.

FAQ

Common questions

Is my data uploaded anywhere?
No. Parsing, editing, and generating output all run in your browser using JavaScript — the CSV you paste or upload never touches a server.
How large a file can I convert?
There's no server-side limit because there's no server involved — your browser's own memory is the ceiling.
What happens if a row has the wrong number of columns?
The parser expects every row to have the same number of comma-separated values as the header row and flags "Invalid CSV format" if one doesn't — fix the mismatched row and it'll re-parse as you type.
Can I edit the data before converting?
Yes — the table below the input lets you transpose rows and columns, delete blank rows, or remove duplicate rows before you generate the final output.
