要捕捉Excel信息并通过电子邮件发送它们，可以使用Python的openpyxl库来读取Excel文件，然后使用smtplib库来发送电子邮件。

下面是一个示例代码，演示了如何使用openpyxl库读取Excel文件的内容，并使用smtplib库发送电子邮件。

import openpyxl
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

# 读取Excel文件的内容
def read_excel(file_path):
    workbook = openpyxl.load_workbook(file_path)
    sheet = workbook.active
    data = []
    for row in sheet.iter_rows(values_only=True):
        data.append(row)
    return data

# 发送电子邮件
def send_email(sender, receiver, subject, message):
    smtp_server = "smtp.example.com"
    smtp_port = 587
    smtp_username = "your_username"
    smtp_password = "your_password"

    msg = MIMEMultipart()
    msg["From"] = sender
    msg["To"] = receiver
    msg["Subject"] = subject

    body = MIMEText(message, "plain")
    msg.attach(body)

    server = smtplib.SMTP(smtp_server, smtp_port)
    server.starttls()
    server.login(smtp_username, smtp_password)
    server.send_message(msg)
    server.quit()

# 主程序
def main():
    file_path = "path/to/excel/file.xlsx"
    sender = "sender@example.com"
    receiver = "receiver@example.com"
    subject = "Excel Data"
    message = ""

    data = read_excel(file_path)
    for row in data:
        message += "\t".join(str(cell) for cell in row) + "\n"

    send_email(sender, receiver, subject, message)

if __name__ == "__main__":
    main()

请确保在运行代码之前，你已安装了openpyxl和smtplib库，并且将代码中的文件路径、发件人、收件人、SMTP服务器等信息替换为你自己的信息。
