IMAP Email Parser: Parse Emails From Any IMAP Mailbox to Excel and CSV
Turn any IMAP mailbox into a clean spreadsheet
Most email parsers only speak Gmail and Microsoft 365. MailParse also connects over plain IMAP, so a mailbox on Fastmail, Zoho Mail, cPanel, Rackspace, or your own mail server works the same way. Point it at the folder, pick the fields you want as columns, and get Excel, CSV, or JSON back.

An IMAP email parser connects to a mailbox over the IMAP protocol, reads each message, and writes the fields you name into rows and columns. MailParse connects to any IMAP server with your host, port, and credentials, then parses the headers, message body, and HTML tables into named fields you export as Excel, CSV, or JSON. It records each attachment by filename, type, and size. You do not write a Python script and you are not limited to Gmail or Outlook.

IMAP is the protocol nearly every mail server speaks. It is how your mail client sees the messages that live on the server instead of downloading and deleting them, and it is the reason the same inbox looks identical on your laptop and your phone. If your company runs mail on Fastmail, Zoho Mail, Rackspace, a cPanel host, or a mail server you administer yourself, IMAP is very likely how you already connect to it.
That matters for parsing, because most email parsing tools were built around two doors: a Gmail OAuth button and a Microsoft 365 button. If your mail lives anywhere else, you are told to write a script. The usual advice is Python's imaplib plus the email module, which means you now own code that logs in, walks the folder, decodes MIME, handles character sets, and writes a CSV, forever, for what started as a reporting request.
MailParse treats IMAP as a first-class connection. Give it the host, port, username, and password, and it reads the folder you choose, parses each message into the fields you name (sender, date, subject, and values pulled out of the body text or an HTML table), and exports the result to Excel, CSV, or JSON. It syncs incrementally, so a second run only pulls messages that arrived since the last one. Attachments are recorded by filename, type, and size, so you can see what came with each message. To read what is inside a PDF or image attachment, extract the file separately with a document data extraction tool; MailParse reads the email itself.
What the converter does
Everything you need to turn a pile of email files into a spreadsheet your team can actually use.
Works with any IMAP server
Fastmail, Zoho Mail, cPanel and shared hosting, Rackspace, Proton Bridge, or a mail server you run. If it speaks IMAP, MailParse connects to it.
No Python, no imaplib
Skip the script that logs in, decodes MIME, and handles character sets. Connect the mailbox in a form and pick your columns instead.
Incremental sync
MailParse tracks where it left off and pulls only new messages on the next run, so a large mailbox is not re-downloaded every time.
Named fields, not a text dump
Pull an invoice total, order ID, or ticket number out of the message body into its own column, alongside the standard headers.
HTML tables become rows
When a message contains an HTML table, such as a report or an order summary, each table row can be written as its own spreadsheet row.
Folders, not just the inbox
Point the parser at any IMAP folder, including an archive or a filtered label, so you parse exactly the mail you care about.
How to convert EML and MSG files to a spreadsheet
Four steps from raw email files to a clean CSV, Excel, or JSON file.
Add your IMAP details
Enter the mail server host, port (usually 993 for IMAP over SSL), username, and password, the same details your mail client uses.
Choose a folder
Pick the inbox or any folder on the server. MailParse reads the messages there rather than pulling the whole account.
Name your columns
Tick the standard headers you want and add custom fields for values in the body, like invoice_total or po_number.
Export and re-run
Download Excel, CSV, or JSON. The next sync pulls only messages that arrived since the last one, using the same field mapping.
Who converts EML and MSG files to CSV
Teams that deal with email in volume and need it as structured data.
Businesses not on Gmail or Microsoft
Companies running mail on Fastmail, Zoho, or a cPanel host get the same parsing workflow as a Google Workspace shop, with no migration.
Finance and AP teams
Parse invoice and remittance emails arriving at a billing@ address into a spreadsheet with vendor, amount, and due date columns.
Operations and order desks
Turn order and dispatch notifications landing in a shared IMAP mailbox into a live sheet your team can sort and report on.
Developers who inherited a script
Replace the imaplib cron job nobody wants to maintain with a mapped connection that exports the same CSV.
Why an IMAP parser beats writing the script
No mailbox code to maintain
An imaplib script has to handle login, folder state, MIME decoding, and encodings. That is code you own and debug every time a sender changes format.
Any host, one workflow
Gmail-only and Microsoft-only parsers force a migration or a script. IMAP works with the mail server you already pay for.
Fields, not raw text
A script usually dumps the body into one cell. MailParse maps named values and HTML table rows into real columns.
Repeatable, not one-off
Save the field mapping once and every future sync produces the same clean spreadsheet, without editing code.
Ways to get data out of an IMAP mailbox, compared
There are three common routes from an IMAP mailbox to a spreadsheet, and each wins somewhere. Here is an honest comparison. If your mail is on Gmail or Microsoft 365, the dedicated Gmail parser and Outlook parser pages cover those routes, and the best email parser guide compares the wider field.
| What matters | MailParse (IMAP connection) | Python imaplib script | Export to .eml, then convert |
|---|---|---|---|
| What it does | Connects to the IMAP folder and writes each message to a row | Your code logs in, walks the folder, and decodes each message | You save messages out of a mail client, then convert the files |
| Setup and skills needed | Host, port, username, password in a form | Python, MIME knowledge, and somewhere to run the job | None, but the export is manual every time |
| Ongoing maintenance | None, the field mapping is saved and reused | You own the code, the cron job, and the edge cases | A person repeats the export whenever data is needed |
| Body field extraction | Name a value in the body and it becomes its own column | Anything you can code a rule or regex for | Depends on the converter, often headers only |
| Incremental runs | Yes, only new messages are pulled on the next sync | Yes, if you write and store the UID tracking yourself | No, you re-export by hand |
| Best for | Teams on any mail host who want a repeatable spreadsheet | Developers who want total control and will maintain code | A one-off pull of a handful of messages |
Capabilities described as of July 2026. MailParse reads the message itself: headers, body text, and HTML tables. Attachments are recorded by filename, type, and size, and reading the contents of a PDF or scanned file is a separate document extraction job.
Frequently asked questions
What is an IMAP email parser?
An IMAP email parser is a tool that logs in to a mailbox over the IMAP protocol, reads the messages in a folder, and turns each one into structured data. Instead of showing you the email, it maps the sender, date, subject, and values from the body into named fields you can export as a spreadsheet or JSON.
How do I parse emails from an IMAP mailbox?
Connect the mailbox with its IMAP host, port, username, and password, choose the folder you want to read, and name the fields that should become columns. MailParse then reads each message, pulls those values from the headers and body, and exports the result to Excel, CSV, or JSON. Later syncs pull only new mail.
Is my email IMAP or POP?
If the same inbox looks the same on your phone and your laptop, and messages stay on the server after you read them, you are almost certainly on IMAP. POP downloads mail to one device and usually removes it from the server. Your mail host lists the setting under incoming mail server, typically IMAP on port 993.
Do I need Python to parse IMAP email?
No. The common answer online is a script built on Python's imaplib and email modules, which works but leaves you maintaining login handling, MIME decoding, and character sets. MailParse connects to the same IMAP server through a form and produces the spreadsheet without any code.
What is an IMAP email extractor?
It is the same idea as a parser: software that pulls data out of the messages in an IMAP mailbox. The useful distinction is what you get back. An extractor that only copies whole message text saves little time, while a parser maps specific values, such as an invoice number or order total, into their own columns.
Which mail hosts work with an IMAP parser?
Any host that offers IMAP access, which is nearly all of them. That includes Fastmail, Zoho Mail, Rackspace, cPanel and shared hosting mailboxes, and mail servers you run yourself. Gmail and Microsoft 365 also support IMAP, though for those two a direct account connection is usually simpler.
Can I export emails from IMAP to Excel?
Yes. Once the mailbox is connected and your columns are chosen, MailParse writes every message in the folder as a row and exports an .xlsx workbook, a CSV, or JSON. Because the mapping is saved, you can re-run the same export whenever new mail arrives instead of rebuilding it.
Is it safe to connect my IMAP mailbox?
The connection uses IMAP over SSL, normally port 993, so credentials and message data are encrypted in transit. Use a dedicated mailbox or an app password where your host supports one, and point the parser at a single folder rather than the whole account, so it reads only the mail you intend it to read.
Can an IMAP parser read my attachments?
MailParse reads the email itself, meaning the headers, the message body, and any HTML tables in it, and records each attachment by filename, type, and size. It does not read the contents of a PDF or scanned image. To pull fields out of an attached document, run that file through a document extraction tool separately.
