PHPExcel is a PHP spreadsheet library used for programmatically reading and writing spreadsheet files in various formats. It utilizes an in-memory spreadsheet model that maps spreadsheet structures to a hierarchy of objects for programmatic manipulation. The library functions as an Office Open XML processor for generating and manipulating XLSX documents and serves as a reader for extracting data and structure from legacy binary XLS files. It also includes tools for CSV data integration and importing. The project provides capabilities for automated report generation and spreadsheet data extra

Templ is a type-safe HTML templating engine and UI framework for Go. It provides a system for building reusable HTML components that compile into Go code for server-side rendering, ensuring type safety and compile-time validation of data and logic. The project features a dedicated language server that provides autocomplete and syntax validation for template files within supported code editors. It employs compile-time code generation to transform a custom template language into Go source code, enabling the creation of modular HTML fragments and logic blocks. The framework includes automated s

PHPWord is a PHP word processing library used for programmatically reading and writing word processing documents. It functions as an OOXML document generator, a word file parser, and a document template engine. The library enables the generation of new documents by applying structured data to existing templates or by creating files from scratch. It provides capabilities for extracting and parsing content, metadata, and structure from existing word processing files. The project covers a broad range of document generation features, including layout formatting, metadata management, and the inse

Acest proiect este un framework distribuit de web crawling headless Chrome și de extracție a datelor. Funcționează ca un motor de randare JavaScript care utilizează un browser headless pentru a procesa pagini dinamice, extrăgând date structurate de pe site-uri web care necesită execuție JavaScript. Sistemul este conceput pentru colectarea scalabilă a datelor pe mai multe noduri, utilizând sincronizarea distribuită a sarcinilor și cache-uri partajate pentru a preveni munca duplicată. Se distinge prin capacitatea de a emula medii client specifice prin configurarea user-agent-urilor și a dimensiunilor viewport-ului, capturând în același timp dovezi vizuale precum capturi de ecran ale paginilor. Framework-ul acoperă gestionarea cuprinzătoare a crawl-ului, inclusiv programarea cererilor în cozi de prioritate, traversarea depth-first și breadth-first și respectarea fișierelor robots.txt și sitemap.xml. Oferă instrumente pentru limitarea concurenței, monitorizarea evenimentelor și streaming-ul datelor extrase în formate CSV sau JSON.

AiNiee is an LLM-based localization tool that automates the translation of games, books, subtitles, and documents across multiple languages. It operates as a batch processing engine, translating entire folders of files in parallel while preserving directory structure, and includes a glossary management system that enforces terminology consistency using AI-powered glossaries, forbidden terms, and user-defined text substitution rules. The tool differentiates itself through key architectural decisions: it distributes translation requests across multiple API keys to bypass rate limits and acceler

ExcelDataReader este o bibliotecă C# utilizată pentru a extrage date și metadate din foile de calcul Microsoft Excel și fișierele CSV. Funcționează ca un parser de workbook care convertește conținutul foilor de calcul în seturi de date structurate pentru acces și iterație programatică.
