Motivation During usage, we may need to convert read or written data into specific formats. Apache Fesod (Incubating) provides a flexible converter mechanism that allows users to define custom data conversion rules to meet various business requirements. Many converter classes are already built in, but some are still missing. How to complete Please link this issue in the description of the PR. This will be a long-term task, allowing all the volunteers to divide it into multiple PRs for completion. Each PR can contain one or more converters, and each converter needs to provide the corresponding unit test code. Only classes compatible with JDK 8 are supported. Each converter must implement the org.apache.fesod.sheet.converters.Converter interface, and please leave a comment outlining your specific implementation proposal. Task List The following are some conversions that are currently required java.sql.Timestamp @SyedIshmumAhnaf java.sql.Clob @AhmedYoussef98 java.time.ZonedDateTime @a

Background Apache Fesod (Incubating), formerly FastExcel, originated as a fork of Alibaba EasyExcel.

To comply with ASF policies, we must apply the standard ASF license headers while strictly retaining the original Alibaba attribution in the derived files. Current Status & Reference To unblock the 2.0.1-incubating release, we have already updated the project-level NOTICE and switched to DISCLAIMER-WIP (see PR #834). The next step is the long-term task of updating the license headers in individual source files across the entire codebase. For a practical
