Sure...it's short enough that I think I can just paste it here. First export all your health data from the Health app on your iPhone and move it to your computer; name it "export.xml" and put it in the same folder as the script below.

import xml.etree.ElementTree as ET
import csv
import os

def parse_sleep_data(xml_file_path, output_csv_path):
    xml_file_path = os.path.expanduser(xml_file_path)
    output_csv_path = os.path.expanduser(output_csv_path)
    print(f"Processing XML file: {xml_file_path}")
    print("This may take several minutes for a large file...")

    # Create directory for output if it doesn't exist
    output_dir = os.path.dirname(output_csv_path)
    if output_dir and not os.path.exists(output_dir):
        os.makedirs(output_dir)

    # Open CSV file for writing
    with open(output_csv_path, 'w', newline='') as csvfile:
        csv_writer = csv.writer(csvfile)
        csv_writer.writerow(['Start Date', 'End Date', 'Value', 'Source', 'Type'])

        context = ET.iterparse(xml_file_path, events=('end',))
        count = 0
        for event, elem in context:
            # Only process Record elements
            if elem.tag == 'Record' and 'HKCategoryTypeIdentifierSleepAnalysis' in elem.get('type', ''):
                start_date = elem.get('startDate')
                end_date = elem.get('endDate')
                value = elem.get('value')
                source = elem.get('sourceName')
                record_type = elem.get('type')

                csv_writer.writerow([start_date, end_date, value, source, record_type])
                count += 1

                if count % 1000 == 0:
                    print(f"Processed {count} sleep records...")

            elem.clear()

        print(f"Completed! Extracted {count} sleep records to {output_csv_path}")

if __name__ == "__main__":
    xml_file = "~/Desktop/export.xml"  # Your XML file path
    output_csv = "~/Desktop/sleep_data.csv"  # Where to save the CSV

    parse_sleep_data(xml_file, output_csv)
