What You’ll Need to Get Started

Before we jump into the “how-to” part, here’s a quick list of what you’ll need:

• Email export format: Most email clients allow you to save emails in formats like `.eml`, `.msg`, `.mbox`, or `.pst`. Familiarizing yourself with these formats is crucial for selecting the right solution.
• An open-source tool: Popular tools like Python-based libraries or email parsers will do the job.
• Installed dependencies: Tools like Python require dependency installations such as Pandas, Imaplib, or BeautifulSoup.
• Excel application: Make sure you have Excel or an equivalent application to manage the converted data.

Easy Guide to Convert Mail to Excel Open Source

Just follow these steps:

#1. Export Your Emails

Start by exporting your emails from your mail client. Different email clients have varied options:

• Gmail users can use Google Takeout to export data as `.mbox` files.
• Outlook users can save their emails as `.eml` or `.pst` files.
• Thunderbird also supports `.mbox` export options.

Once you’ve exported your emails, store them in a clear folder for easy access.

#2. Choose the Right Open-Source Tool

Here are some popular open-source tools for the task:

• Python (Pandas Library + Email libraries)

Python enables advanced data extraction and cleaning. Libraries like `Imaplib`, `Email`, and `Pandas` can parse email data and convert it into an Excel-compatible format effortlessly.

• Email Parser by Open Source

This community-supported tool focuses solely on extracting email content and exporting it to CSV or Excel format.

• LibreOffice Calc with Mail Extensions

LibreOffice supports importing email data for manipulation and further export to Excel.

#3. Write a Python Script

A Python script is one of the most flexible ways to extract and customize the conversion process. Here’s a simple script to get started:

Sample Python Code:

“`

import os

import pandas as pd

from email import policy

from email.parser import BytesParser

Path to email files

email_folder = ‘path_to_email_files’

output_excel = ‘output.xlsx’

List to hold extracted data

email_data = []

Process email files

for file in os.listdir(email_folder):

if file.endswith(‘.eml’): # Ensure email file format is .eml

with open(os.path.join(email_folder, file), ‘rb’) as f:

msg = BytesParser(policy=policy.default).parse(f)

email_data.append({

‘Subject’: msg[‘subject’],

‘From’: msg[‘from’],

‘Date’: msg[‘date’],

‘Body’: msg.get_body(preferencelist=(‘plain’)).get_content()

})

Convert to DataFrame and Export to Excel

df = pd.DataFrame(email_data)

df.to_excel(output_excel, index=False)

“`

#4. Use Email Parsers

If coding isn’t your cup of tea, you can opt for preconfigured email parsers like Mailparser.io or other open-source alternatives. Simply load your email data file (e.g., `.mbox` or `.eml`) into the tool, map the fields you want, and export to Excel.

#5. Import to Excel

Once your data is converted into CSV or compatible files, open Excel and use the import wizard to map fields for proper structuring. Use Excel’s built-in filters and sorting options to organize the data further.

Pro Tip: Data conversion can sometimes lead to errors or misalignment. Always verify the output by cross-checking a few data points against the original emails to ensure everything is mapped correctly.

Important Tip: Don’t repeat the process manually every time. Use automation tools like task schedulers or custom scripts with cron jobs to periodically extract and update your email data into Excel.
