有哪些选项可以调整？What options can I adjust?

「CSV URL 编码（编码单元格）」的设置：「列（留空 = 全部）」可留空；可勾选：「空格编码为 +（application/x-www-form-urlencoded）」、「第一行是表头」（默认勾选）、「也编码表头」。改动任一选项后结果会按新设置重新生成。You can adjust "Columns (blank = all)" (optional); and the "Encode spaces as + (form encoding)", "First row is a header" (on by default) and "Also encode the header" checkboxes. The result updates as soon as you change a setting.

行长度不一致（有的行字段多、有的行字段少）时会怎样？What happens when rows have different numbers of fields?

不会凭空补字段，也不会删掉字段：操作只作用于每行实际存在的字段，每行保持自己原来的长度。比如某行没有要处理的那一列，这一行就原样保留。检测到这种行时，结果下方会有一行提示说明有几行。需要统一列数时，请用“CSV 补齐不完整行”。No fields are invented or dropped: the operation only touches the fields each row actually has, and every row keeps its own length. If a row does not have the column being changed, that row is left as it is. When such rows are found, a one-line note below the result says how many. To give every row the same number of fields, use Fill Incomplete CSV Records.

代码或数据会被上传吗？Is my code or data uploaded?

不会。「CSV URL 编码（编码单元格）」完全用 JavaScript 在本地运行，适合处理含有密钥、内部接口等敏感内容的数据。No. The URL-Encode CSV tool runs entirely in local JavaScript, so it is safe for data containing keys or internal endpoints.
