如何使用「矩阵与 JSON 二维数组互转」？How do I use the Matrix ⇄ JSON 2D Array Converter?
粘贴矩阵（每行一行，元素用空格、Tab 或逗号分隔）或 JSON 二维数组，工具会自动识别输入格式，选择输出格式即可。数字会自动转成数值，非数字保留为字符串。Paste a matrix (one row per line, elements separated by spaces, tabs or commas) or a JSON 2D array; the input format is detected automatically — just pick the output format. Numbers become numeric values and anything else stays a string.
能识别哪些输入格式？Which input formats are recognised?
JSON 二维数组、每行一行的空格/Tab/逗号分隔文本，以及 MATLAB 风格的分号换行写法（如 [1 2; 3 4]）都能识别。JSON 2D arrays, rows of space/tab/comma-separated text, and MATLAB-style semicolon rows such as [1 2; 3 4].
