Importing data from Excel spreadsheets into your database is a valuable skill for any creative professional who works with data. In this article, we will explore several methods for importing Excel data into MySQL and Python, as well as tips and tricks to make the process smoother.

Importing Excel Data to MySQLi

If you are using PHP 7, MySQLi is a fast and easy way to connect to your MySQL database. Here are the steps to import your Excel file:

  1. First, make sure that your Excel file is formatted correctly. Use only one worksheet in your file, and make sure that all your data is in the first row.
  2. Next, create your connection to the database. You will need to enter your database credentials (such as your server name, username, and password) to establish the connection. Here is an example:
  3. $servername = "localhost";
    $username = "username";
    $password = "password";
    $dbname = "database_name";
    $conn = new mysqli($servername, $username, $password, $dbname);
  4. Now, you need to create a table in your database to store the Excel data. You can use the following SQL code to create a basic table:
  5. CREATE TABLE excel_data (
    first_name VARCHAR(30) NOT NULL,
    last_name VARCHAR(30) NOT NULL,
    email VARCHAR(50),
  6. Once your table is set up, you can use PHPExcel to load your Excel file and insert the data into your table. Here is an example:
  7. require_once 'PHPExcel/PHPExcel.php';
    $objReader = PHPExcel_IOFactory::createReader('Excel2007');
    $objPHPExcel = $objReader->load("myExcelFile.xlsx");
    $worksheet = $objPHPExcel->getActiveSheet();
    $numRows = $worksheet->getHighestRow();
     $lastName = $worksheet->getCellByColumnAndRow(1,$i)->getValue();
     $email = $worksheet->getCellByColumnAndRow(2,$i)->getValue();
     $sql = "INSERT INTO excel_data (first_name, last_name, email) VALUES ('$firstName', '$lastName', '$email')";

Importing Excel Data to Python

If you are working with Python, there are several libraries that you can use to import Excel data. Here are the steps to import your Excel file using the pandas library:

  1. First, make sure that you have pandas installed on your machine. If you are using Anaconda, pandas is already installed. Otherwise, use pip to install it:
  2. !pip install pandas
  3. Next, read your Excel file into a pandas DataFrame. Here is an example:
  4. import pandas as pd
    df = pd.read_excel('myExcelFile.xlsx', sheet_name='Sheet1')
  5. You can also use the xlrd library to read your Excel file:
  6. import xlrd
    workbook = xlrd.open_workbook('myExcelFile.xlsx')
    worksheet = workbook.sheet_by_name('Sheet1')
    for row in range(1, worksheet.nrows):
     first_name = worksheet.cell(row, 0).value
     last_name = worksheet.cell(row, 1).value
     email = worksheet.cell(row, 2).value
     # Insert data into database
  7. Once you have your data loaded into a DataFrame, you can use pandas to manipulate, analyze, or visualize your data.


Q. How do I troubleshoot errors when importing Excel data?

A. When importing data from Excel, you may encounter errors or issues that prevent the data from being loaded correctly. Here are some tips to help you troubleshoot:

  1. Check that your Excel file is formatted correctly. Make sure that you have only one worksheet and that your data is in the first row.
  2. Check that your Excel file is not open or in use by another user. This can cause errors when trying to load the data.
  3. Check that your database connection is set up correctly. Make sure that you have entered the correct credentials and that your server is running.
  4. Check that your SQL queries are correct. Make sure that you have specified the correct table name and column names, and that your data types match the columns in your table.
  5. Make sure that you are using the correct file format. If you are using Python, you may need to use xlrd to read older Excel file formats.

Q. How do I import data from multiple Excel files?

A. If you have multiple Excel files that you need to import, you can loop through each file and load the data into your database or DataFrame. Here is an example using Python and pandas:

import pandas as pd
import glob
all_files = glob.glob('./*.xlsx')
df_list = []
for file in all_files:
 df = pd.read_excel(file, sheet_name='Sheet1')
combined_df = pd.concat(df_list)

This code loops through all the Excel files in the current directory and loads each file into a pandas DataFrame. The DataFrames are then concatenated into a single DataFrame.


Importing data from Excel spreadsheets can be a time-consuming task, but with the right tools and techniques, you can streamline the process and make it more efficient. Whether you are working with MySQLi or Python, there are many resources available to help you import your data quickly and accurately.
