导出ES数据到excel

首先通过elasticdump组件将线上指定的index导出成文本文件
elasticdump --input=“http://192.168.0.30:9200/adv_default” --output=“/bigdata/adv_default.data” --type=data --li
————————————————

数据结构如下

}

利用java将文件转为excel

public static void main(String[] args) throws IOException {
    // 假设data文件是一个文本文件，每行是一个Excel行
    File dataFile = new File("C:\\Users\\tytu\\Desktop\\fsdownload\\es-data\\ods_data_vsanonmotorvehicle_202410.data");
    Workbook workbook = new XSSFWorkbook();
    Sheet sheet = workbook.createSheet("Data");
    // 读取data文件并写入Excel
    try (BufferedReader reader = new BufferedReader(new FileReader(dataFile))) {
        int rowNum = 0;
        while (reader.ready()) {
            String json = reader.readLine();
            JSONObject jsonObject = JSONObject.parseObject(json, JSONObject.class);
            JSONObject source = jsonObject.getJSONObject("_source");
            Row row = sheet.createRow(rowNum);
            if (rowNum == 0) {
                int colNum2 = 0;
                for (String s : source.keySet()) {
                    Cell cell = row.createCell(colNum2);
                    cell.setCellValue(s);
                    ++colNum2;
                }
            } else {

                int colNum3 = 0;
                for (Object value : source.values()) {
                    Cell cell = row.createCell(colNum3);
                    if (value == null) {
                        cell.setCellValue("");
                    } else {
                        cell.setCellValue(value.toString());
                    }
                    ++colNum3;
                }
            }
            ++rowNum;
        }
    }

    // 写入Excel文件
    String f=   dataFile.getPath();
    String substring = f.substring(0, f.lastIndexOf("."));
    try (FileOutputStream outputStream = new FileOutputStream(substring+".xlsx")) {
        workbook.write(outputStream);
    }

    System.out.println("Data written to Excel successfully.");
}

通过python脚本



```python
import json
import pandas as pd
json_file_path = 'C:\\Users\\tytu\\Desktop\\fsdownload\\ods_data_vsahuman_202410.data'
with open(json_file_path, 'r', encoding='utf-8') as file:
    json_data = file.readlines()
data_list = []
for line in json_data:
    json_line = json.loads(line)
    source_data = json_line['_source']
    data_list.append(source_data)
df = pd.DataFrame(data_list)
excel_output_file = json_file_path.split('.')[0] + '.xlsx'
df.to_excel(excel_output_file, index=False)
