jq is a lightweight and flexible command-line JSON processor akin to sed,awk,grep, and friends for JSON data. It's written in portable C and has zero runtime dependencies, allowing you to easily slice, filter, map, and transform structured data.

Download jq. jq is written in C and has no runtime dependencies, so it should be possible to build it for nearly any platform. Prebuilt binaries are available for Linux, macOS and Windows. The binaries should just run, but on macOS and Linux you may need to make them executable first using chmod +x jq. jq is licensed under the MIT license.

jq is a lightweight and flexible command-line JSON processor. Try online! jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. jq is written in portable C, and it has zero runtime dependencies.

jq filters run on a stream of JSON data. The input to jq is parsed as a sequence of whitespace-separated JSON values which are passed through the provided filter one at a time. The output (s) of the filter are written to standard output, as a sequence of newline-separated JSON data.

jq 用于处理JSON输入，将给定过滤器应用于其JSON文本输入并在标准输出上将过滤器的结果生成为JSON。 最简单的过滤器是.，它将jq的输入未经修改地复制到其输出中（格式设置除外）。 请注意，jq 当前仅支持64位双精度浮点数（IEEE754）。 安装 # Debian系，如 Ubuntu

jq is a very high-level lexically scoped functional programming language in which every JSON value is a constant. jq supports backtracking and managing indefinitely long streams of JSON data. It is related to the Icon and Haskell programming languages.

jq 一般将 非-ASCII 的 Unicode 字符使用 UTF-8 输出，即使输入的时候可能是转义后的序列(如 “\u03bc”)。使用这个选项，可以强制 jq 生成纯 ASCII 输出，其中每个 非-ASCII 字符将用等价的转义序列替换。--unbuffered:
