    EasyExcel

    EasyExcel

    Lightweight Java library developed by Alibaba for reading and writing

    ...It uses streaming/event-driven parsing to avoid loading entire workbooks into memory, and it maps rows to Java objects via simple annotations. Writers support multiple sheets, custom styles, merged cells, and template-based filling so production reports remain maintainable. The API emphasizes developer ergonomics: callbacks are straightforward, converters handle common type transformations, and header/column mapping is explicit. It integrates cleanly into Spring/enterprise stacks, often as part of import/export pipelines or scheduled report generation. By optimizing both performance and ease of use, EasyExcel reduces operational risk around big Excel jobs in web services and back-office tools.

    Official Android SDK for Stream Chat

    Official Android SDK for Stream Chat

    Android Chat SDK ➜ Stream Chat API. UI component libraries for chat

    This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components and fall back to the lower-level API when they want to customize things. We're proud to say that we're the first Android Chat SDK that supports Jetpack Compose! We released our Compose UI Components one day after the official Jetpack Compose 1.0 release and our team members have been working hard on it since then. Now it's mature and stable enough for us to officially recommend it for all new applications and all modern chat implementations. ...
