Found a bug?
If a tool misbehaves, tell us which tool you were using, the file format involved, and what you expected to happen. Because your files never leave your browser, we cannot see them — a small sample file that reproduces the problem (with nothing sensitive in it) helps enormously.
Suggestions welcome
Want a new tool, a new format, or a public dataset added to the data catalog? Send us a note — many of the tools on this site started as visitor suggestions.
