JXL

jXL is not a single, universally defined term. It is used in multiple domains to denote different things that share only the initials. Because the meaning depends on the context, a precise definition requires identifying the specific field or source in which the term appears.

In software development, jXL is often encountered as a Java library associated with Excel file handling. It is described as a lightweight API for reading and writing data in the legacy Excel .xls format, providing access to workbooks, sheets, rows, and cells through a straightforward programming model. The library tends to be used in older Java applications where minimal dependencies were preferred. It generally does not support the newer .xlsx format and may omit some advanced features found in larger libraries.

In other contexts, jXL can serve as a project name, product code, or brand acronym. Because the term is not unique, the exact scope, capabilities, and licensing depend on the specific implementation or organization behind it. Users should consult the relevant documentation to understand what jXL refers to in that case.
