[FilterJSONByPredicate]

Usage

FilterJSONByPredicate filters the JSON data based on a specified predicate function, allowing conditional inclusion of elements in the resulting JSON.

filteredJSON, err := FilterJSONByPredicate(jsonData, func(key string, value interface{}) bool {
    return key == "desiredKey" // Example predicate: keep only the key "desiredKey"
})
if err != nil {
    log.Fatal(err)
}
fmt.Println(string(filteredJSON))

Reference

Parameter	Type	Description
inputJSON	[]byte	The input JSON data as a byte slice.
predicate	func(key string, value interface{}) bool	The predicate function to evaluate each key-value pair.

Returns	Description
[]byte	The filtered JSON data as a byte slice.
error	An error if the operation fails, otherwise nil.

[WriteCustomFormattedJSONToFile]

Usage

WriteCustomFormattedJSONToFile writes data to a file in a custom JSON format, allowing for specified indentation.

err := WriteCustomFormattedJSONToFile(data, "output.json", "  ")
if err != nil {
    log.Fatal(err)
}

Reference

Parameter	Type	Description
data	interface{}	The data to be written in JSON format.
filename	string	The name of the file to write the data to.
indentString	string	The string used for indentation in the JSON output.

Returns	Description
error	An error if the operation fails, otherwise nil.

[CleanJSON]

Usage

CleanJSON removes single line (//) and multi-line (/* */) comments from a byte slice containing JSON data, ensuring the remaining data is valid JSON. It also removes trailing commans from the last element in arrays and objects.

cleanData, err := CleanJSON(jsonDataWithComments)
if err != nil {
    log.Fatal(err)
}
fmt.Println(string(cleanData))

Reference

Parameter	Type	Description
data	[]byte	The JSON data with comments as a byte slice.

Returns	Description
[]byte	The cleaned JSON data without comments.
error	An error if the operation fails, otherwise nil.

These functions provide utilities for processing JSON data, such as filtering elements based on conditions, writing data to a file with custom formatting, and removing comments from JSON content.
