将符号分隔的文本文件txt转换为excel的实现

文本文件如下：

现在不好处理，打算将其转换为excel，其中通过冒号分割：line.split(":")
main方法如下：

java 复制代码

 public static void main(String[] args) {
     
        String textFilePath = "D:\\zoom\\期刊\\J_Medline\\J_Medline";  // 替换为你的文本文件路径
        String excelFilePath = "D:\\zoom\\期刊\\J_Medline\\output1.xlsx";  // 生成的 Excel 文件路径

        List<String[]> data = new ArrayList<>();

        try (BufferedReader br = new BufferedReader(new FileReader(textFilePath))) {
            String line;
            while ((line = br.readLine()) != null) {
                String[] fields = line.split(":");
                String strip = StringUtils.strip(Arrays.toString(fields), "[]");
                if(!strip.equals("--------------------------------------------------------")){
                    data.add(fields);
                }

            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        try (Workbook workbook = new XSSFWorkbook()) {
            Sheet sheet = workbook.createSheet("Sheet1");
            int rowNum = 0;

            for (String[] rowData : data) {
                Row row = sheet.createRow(rowNum++);
                int colNum = 0;
                for (String field : rowData) {
                    Cell cell = row.createCell(colNum++);
                    cell.setCellValue(field);
                }
            }
            try (FileOutputStream outputStream = new FileOutputStream(excelFilePath)) {
                workbook.write(outputStream);
                System.out.println("Excel file created successfully: " + excelFilePath);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

其中去掉了横线----------------------------------------，结果如下：
