How It Works

1

Step 1

Load one or many EML files by dragging them into the app or using the file picker

2

Step 2

Choose cleanup options: date normalization, MIME decoding, HTML stripping

3

Step 3

Enable attachment extraction if you need the original attached files alongside the data

4

Step 4

Export a clean CSV ready for Excel, Numbers, Google Sheets, or database import

Use Cases

Email analytics and trend reporting
Export message-level fields into CSV so analysts can quantify communication volume, response times, and sender patterns across large datasets using pivot tables or BI dashboards.
Compliance and communication audits
Transform scattered EML files from mailbox exports into one searchable, filterable table for compliance officers to review sender-recipient relationships and flag policy violations.
CRM and database enrichment
Extract contact information, subject lines, and timestamps from email archives and merge them with CRM records, support ticket logs, or marketing automation platforms.

Compatible Sources & Providers

Works with all major email clients, cloud services, and data sources.

Microsoft Outlook

Import EML exports from Outlook and convert them into clean, structured rows and columns ready for analysis.

Apple Mail

Process saved messages from Apple Mail and get consistent field extraction across every EML file.

Helpdesk and support systems

Turn exported ticket emails from platforms like Zendesk, Freshdesk, or Intercom into structured CSV for SLA tracking and workload analysis.

Newsletter and campaign archives

Extract campaign-related email data into CSV for content audits, response tracking, and marketing performance reviews.

Migration tool exports

Normalize EML backup files produced by migration tools before platform switches or archival cleanup projects.

How It Compares

SysTools EML Converter

Typical use

A desktop tool available on Windows and Mac that converts EML files into multiple formats including PST, MSG, MBOX, and PDF. Starts at $29 one-time. Often used as part of broader migration toolkits.

Great Apps advantage

EML to CSV is laser-focused on producing clean spreadsheet output with built-in data cleaning. While SysTools covers many formats, it does not emphasize CSV-specific cleanup like MIME decoding, date normalization, or HTML stripping the way EML to CSV does.

Aid4Mail

Typical use

An enterprise email forensics and migration platform supporting 40+ formats with advanced filtering and search. Designed for legal, eDiscovery, and large-scale migration teams.

Great Apps advantage

EML to CSV is simpler and faster to operate for reporting-oriented exports. Non-technical team members can produce clean CSV output without learning a complex enterprise tool or managing migration-scale licensing.

Custom parsing scripts (Python, PowerShell)

Typical use

Technical teams often write custom scripts to parse EML files using libraries like Python email or PowerShell. Flexible but requires coding skills and ongoing maintenance.

Great Apps advantage

EML to CSV removes scripting overhead and gives non-developers a repeatable, visual workflow with built-in cleanup options. No code to write, no libraries to maintain, and consistent output every time.

Frequently Asked Questions

What data fields does EML to CSV extract?

The app extracts sender, recipient, CC, BCC, subject, date, and message body from each EML file and organizes them into consistent spreadsheet columns.

Can I process thousands of EML files at once?

Yes. The full version supports batch processing of large EML collections with consistent column output across every file in the batch.

Does EML to CSV handle encoded email content?

Yes. The app automatically decodes Base64 and quoted-printable encoded text and converts it into clean, human-readable strings in the CSV output.

Is my email data sent to any server during conversion?

No. All processing happens locally on your Mac. Your email content never leaves your device.

Can I extract email attachments along with the CSV data?

Yes. The app can save all attachments to a separate folder while generating the CSV spreadsheet, so you get structured data and original files together.

What is the difference between EML to CSV and writing a script?

EML to CSV provides a visual, no-code workflow with built-in cleanup for dates, encodings, and HTML. Scripts require programming skills, library management, and manual testing for edge cases.

Who typically uses EML to CSV?

Data analysts, marketing operations teams, compliance reviewers, researchers, and IT migration specialists who need email archives in spreadsheet-ready form.

What macOS version is required?

EML to CSV requires macOS 10.15 (Catalina) or later.
