### 4.1 Table Formats

TOPCAT supports a number of different serialization formats for table data; some have better facilities for storing table data and metadata than others.

Since you can load a table from one format and save it in a different one, TOPCAT can be used to convert a table from one format to another. If this is all you want to do however, you may find it more convenient to use the `tcopy` or `tpipe` command line utilities in the STILTS package.

The following subsections describe the available formats for reading and writing tables. The two operations are separate, so not all the supported input formats have matching output formats and vice versa.
