![]() ![]() Here's an example of how you might use cURL and jq together to retrieve and process JSON data from an API: curl | jq '.items | ' data.json This allows you to easily retrieve and process JSON data from APIs in a command-line environment. Together, they can be used to retrieve JSON data from an API and process it with jq. jq is a command-line tool for parsing JSON. So while both JQ and JSONPath are used to work with JSON data, JQ is a more versatile tool that allows you to perform complex data transformations and extractions, while JSONPath is primarily used to extract specific values from JSON documents.ĬURL is a command-line tool for making HTTP requests, and jq is a command-line tool for parsing JSON data. JSON is a lightweight format that is nearly ubiquitous for data-exchange. JSONPath is useful for extracting specific data from a JSON document, but it does not have the same level of functionality for transforming or manipulating JSON data as jq. JSONPath expressions look similar to XPath expressions for XML data. jQuery is a fast, small, and feature-rich JavaScript library. ![]() It allows you to extract specific values from a JSON document using a string-based path expression. ![]() Before using a jq expression in the expr parameter, escape any JSON special characters with a leading backslash (\). Important: The expr parameter requires a valid JSON string value. The article also covers limitations for jq in ZIS. JSONPath, on the other hand, is a query language for JSON data. You can test the expressions using the jq play site or the jq command-line tool. jq is particularly useful for working with nested JSON data and can be used to perform complex transformations on JSON data. It uses a syntax similar to that of the Unix shell and can be used in a pipeline with other command-line tools. jq is a command-line tool that allows you to filter, transform, and extract data from JSON files. The binaries should just run, but on macOS and Linux you may need to make them executable first using chmod x jq. Prebuilt binaries are available for Linux, macOS and Windows. Unfortunately, shells such as Bash can’t interpret and work with JSON directly. jq is written in C and has no runtime dependencies, so it should be possible to build it for nearly any platform. ![]() It’s particularly popular in web applications due to its lightweight nature and compatibility with JavaScript. JQ and JSONPath are both tools for working with JSON data, but they have some key differences in how they operate. Overview JSON is a widely employed structured data format typically used in most modern APIs and data services. For these examples I am using the output derived from a openQA API query. ❯ $issues | ConvertTo-Xml -As String -NoTypeInformation Serious sync issues 2344 docs(manual): fix the typo errors in the manual 2343 Grammar railroad diagram 2342 Question about license.
