Awesome GitHub RepositoriesCSV to JSON Conversion

jc is a tool that transforms plain-text results from command-line utilities, system tools, log formats, and text tables into structured JSON data. It functions as a structured data transformer capable of converting various file formats, including CSV, INI, XML, and YAML, into JSON representations for programmatic use. The project includes a collection of specific parsers for Unix commands and system tools such as df, blkid, and various package managers. It also features specialized converters for web server logs, Common Log Format, and Common Event Format strings. The tool covers broad capab

This project is an administrative GIS toolset that provides a comprehensive dataset of China's administrative divisions, including provinces, cities, districts, and townships. It functions as a coordinate system transformer and a boundary converter for transforming geographic data into standard formats. The toolset distinguishes itself through the ability to convert administrative boundary data between CSV, GeoJSON, Shapefiles, and SQL. It includes specialized utilities for coordinate system transformation between GCJ-02, BD-09, WGS-84, and CGCS2000 standards to ensure accuracy across differe

csvkit is a composable Unix-style command-line toolkit for converting, filtering, and analyzing CSV files directly from the terminal. It provides a suite of focused single-purpose commands that can be combined via pipes to build complex data processing workflows, with a modular architecture that includes a column-type inference engine for automatically detecting data types and a streaming-pipeline design for efficient handling of tabular data. The toolkit distinguishes itself through its SQL-engine abstraction layer, which allows users to run SQL queries directly against CSV files without req

Mapshaper 是一个用于处理、简化和转换地理矢量数据的工具，提供命令行界面、Web 浏览器工具和 Node.js 库。它作为一个坐标投影器、矢量数据转换器和 Web 地图资产优化器，旨在在不同的坐标参考系统和文件格式之间转换空间数据集。 该项目以其拓扑保持几何简化而著称，在减少顶点数量的同时保持共享边界，以防止间隙和重叠。它还通过坐标量化和属性过滤进一步优化 Web 资产，以减小文件大小。 该系统涵盖了广泛的功能，包括使用 PROJ 字符串和 EPSG 代码进行坐标重投影，以及跨 Shapefile、GeoJSON、TopoJSON、GeoPackage 和 KML 等格式的数据转换。它提供了广泛的几何处理工具，用于缓冲、裁剪、溶解和修复拓扑，以及用于属性连接、过滤和转换的数据管理实用程序。此外，它还包括用于生成样式化 SVG 导出、经纬网和比例符号地图的视觉功能。 空间处理功能可以通过其 Node.js 库直接集成到 JavaScript 应用程序和构建流水线中。

qsv is a high-performance command line toolkit for querying, transforming, and analyzing comma-separated value files. It functions as a data wrangling interface and a tabular data profiler, featuring a query engine capable of executing SQL statements and joins directly on flat files without requiring a database. The project is distinguished by its ability to process massive datasets that exceed available system memory. This is achieved through disk-based external memory processing, including multithreaded merge sorting, on-disk hash tables for deduplication, and lightweight file indexing for
