EasyExcel is a Java processing library designed for reading and writing XLS, XLSX, and CSV files. It functions as a memory-efficient spreadsheet parser, an object-relational mapper that binds spreadsheet columns to Java class fields, and a stream-based exporter for handling high-volume data. The library distinguishes itself through a streaming model that processes large files row-by-row via listeners to prevent heap memory overflow. It also operates as a template engine, allowing the population of predefined spreadsheet files with dynamic data while preserving original layouts and styles. Br
Transforms date and numeric cells into strings using custom patterns and rounding modes.
VisiData is a terminal-based interactive data analysis tool and browser designed for exploring, filtering, and sorting large tabular datasets. It functions as a structured data inspector that loads and flattens complex formats like JSON, XML, and PCAP into interactive sheets, as well as a terminal file manager for navigating directories and performing staged filesystem operations. The project distinguishes itself by rendering data visualizations, such as scatter plots and histograms, directly in the terminal using Unicode Braille characters. It provides a Python-based data wrangling environme
Updates values in cells or columns using Python expressions and regex to transform data.
Tabulator is an interactive data table library and virtual DOM data grid used to create high-performance tables from JSON or arrays. It functions as a hierarchical data viewer and a spreadsheet interface component, capable of rendering thousands of records efficiently through viewport-based virtualization and progressive loading. The library distinguishes itself by providing a full spreadsheet interface mode with multi-sheet management, cell range selection, and bulk copy-paste capabilities. It supports complex data architectures, including nested data field mapping, expandable tree structure
Modifies column headers and cell values during the file import process via transformation callbacks.
ExcelDataReader هي مكتبة C# تُستخدم لاستخراج البيانات والبيانات الوصفية من جداول بيانات Microsoft Excel وملفات CSV. تعمل كمحلل لمصنفات العمل (workbook) يحول محتوى جدول البيانات إلى مجموعات بيانات مهيكلة للوصول البرمجي والتكرار. يتضمن المشروع مستخرجاً متخصصاً للبيانات الوصفية لاسترجاع تفاصيل مستوى الخلية، مثل تنسيقات الأرقام، والأنماط، وارتفاعات الصفوف، وعروض الأعمدة، ونطاقات الخلايا المدمجة. كما يوفر معالج تدفق لتحليل ملفات CSV النصية العادية مع ترميز قابل للتخصيص واكتشاف الفواصل. تدعم المكتبة معيار OpenXML لملفات جداول البيانات الحديثة وتستخدم التحليل القائم على التدفق والتكرار القائم على المؤشر للصفوف لاجتياز مصنفات العمل. تمكن هذه الإمكانيات من تحويل مصنفات العمل متعددة الأوراق إلى جداول بيانات علائقية.
Captures formatting and structural properties alongside raw cell values during the parsing process.
