What is Escape JSON String?
This Escape JSON String tool helps you convert plain text into valid JSON string values by escaping special characters. When building JSON payloads, API requests, or configuration files, strings must have their quotes, backslashes, newlines, and tabs properly escaped. This tool automatically converts these characters to their escape sequence equivalents (\", \\, \n, \t), preventing "Unexpected token" errors and ensuring your JSON is syntactically valid.
