Email to CSV: Convert Email and Email Body Data into a CSV File
Turn a message, its body, and a whole inbox into a clean CSV file with one row per email
CSV is the format every spreadsheet and database will import, which is exactly why you want your email data in it. MailParse converts email to CSV for you: connect a mailbox or paste a message, name the fields you want as columns, and download a comma-separated file with the sender, date, subject, and any custom value pulled from the body and attachments, one row per message. Paste a sample below to see the CSV it produces.

- CSV
- One row per email
- Body
- Custom fields from the text
- Tables
- HTML rows into CSV rows
- Bulk
- One message or thousands
A lot of work starts as an email and needs to end up in a spreadsheet or a database: a lead from a web form, an order confirmation from a marketplace, a supplier invoice, a shipping notice. CSV is the format that gets it there, because every tool that holds tabular data (Excel, Google Sheets, Airtable, a SQL import, an accounting package) will read a comma-separated file. The catch is getting from a raw message to a clean CSV. A real email is a MIME document with plain-text and HTML versions of the body, base64-encoded attachments, and headers that vary by sender, none of which maps to rows and columns on its own.
MailParse converts email to CSV so you skip that work. Paste a sample message, connect a Gmail, Outlook, Microsoft 365, or IMAP mailbox, or forward mail to a parsing address, and each message comes back as one CSV row: sender, recipients, date, subject, and the message body, plus the custom fields you name, such as order number, invoice total, or tracking number. HTML tables inside the email become their own rows, attachments are decoded and read, and the file downloads as UTF-8 CSV that opens cleanly in Excel or Google Sheets without a scrambled column in sight. This page covers what a CSV export of email looks like, how to convert one message or a whole inbox, and where a parser saves you from cleaning the data by hand.
What the email to CSV converter does
Everything you need to turn a raw message into a CSV file any tool will import.
Email to one clean CSV row
Every message becomes the same set of columns: sender, recipients, date, subject, body, and your custom fields. You import the CSV once and every email lines up under the same headers, ready to sort, filter, and total.
Custom columns pulled from the body
Name values like order_number, invoice_total, or po_number and the parser finds them in the message body and gives each its own column, so the CSV holds the fields you care about rather than a wall of raw text in one cell.
HTML tables become CSV rows
Order confirmations and reports often carry their data in an HTML table. MailParse reads those rows and writes each one as its own line in the CSV, instead of flattening the whole table into a single cell.
Attachments read into the file
PDFs, CSVs, and spreadsheets attached to the email are decoded from base64 and their data read, so a total or a line item sitting inside an attachment lands in the same CSV as the rest of the message.
Convert one message or a whole inbox
Paste a single email to see its CSV, or connect a mailbox and convert a backlog of thousands in one pass. The columns stay the same whether you export one message or a full queue, so the file is safe to import anywhere.
CSV, Excel, or JSON from one parse
Need a native workbook or a structured object instead? The same parsed result exports to Excel and JSON as well as CSV, so everyone on the team takes the format their next tool expects from a single upload.
How to convert email to CSV
Four steps from a raw message to a clean CSV file.
Add your email
Paste a sample message, upload an EML or MSG file, or connect a Gmail, Outlook, Microsoft 365, or IMAP mailbox so messages flow in automatically.
Name the columns you want
Keep the standard fields and add custom ones to pull from the body and attachments, so the CSV headers match the columns your spreadsheet or database expects.
Get the CSV
MailParse decodes the MIME parts, normalizes the text to UTF-8, reads the tables and attachments, and writes one comma-separated row per message with your headers on top.
Import it anywhere
Download the CSV and open it in Excel or Google Sheets, or feed it into Airtable, a database, or your accounting software, since a CSV imports into practically everything.
Who converts email to CSV
Teams that need email turned into a file their spreadsheet or database will import.
Analysts and operations teams
Turn a stream of order, lead, or notification emails into CSV rows and load them into a sheet or warehouse, so reporting runs on structured columns instead of a mailbox full of messages.
Finance and bookkeeping
Pull vendor, invoice number, date, and total out of emailed invoices and remittance notices into a CSV, ready to import into Excel or an accounting package for reconciliation.
Anyone migrating or archiving a mailbox
Export a folder or a whole inbox to a single CSV so the messages and their key fields live in a portable file you can search, back up, or move into another system.
Low-code and database imports
Get a clean CSV to drop into Airtable, a SQL import, or a CRM, instead of slicing the message body with formulas that break when a sender changes the layout.
Why convert email to CSV with MailParse instead of by hand
No copy and paste
Skip opening each message and typing values into cells. MailParse reads the body and attachments and writes the row for you, so a folder of emails becomes a file instead of an afternoon.
Body data, not just headers
A basic export gives you sender, subject, and date. MailParse also extracts the custom values you name from the body and gives each its own column in the CSV.
Clean UTF-8, no scrambled columns
Renaming an email to .csv produces a mangled grid. MailParse decodes the MIME structure and quotes fields properly, so commas and line breaks inside the text do not split your columns.
Holds up across senders
Formula-based slicing breaks when a layout shifts. MailParse keeps returning the named columns when the email format drifts, so the CSV stays consistent to import.
Ways to convert email to CSV, compared
Getting from a raw message to a clean CSV has a few honest routes, depending on how many emails you handle. Here is how they line up on the choices you actually make. To pull specific values out of the message text, see extracting data from Outlook emails.
| What matters | MailParse | Copy and paste | Rename .eml to .csv | Outlook / Excel export |
|---|---|---|---|---|
| What it does | Writes one clean CSV row per email with named columns | You retype each value into cells by hand | You change the file extension and hope | Exports whole messages or basic metadata |
| Body field extraction | Name order_number or total and get it as a column | You read and type each field yourself | None, the file is still raw MIME text | Headers and body dump, not chosen fields |
| HTML tables | Each table row becomes a CSV row | You copy the table cell by cell | Left as encoded text | Usually flattened or dropped |
| Attachments | Decoded and read, data pulled into the CSV | You open each file and copy from it | Ignored, left inside the raw file | Saved as files, not read into columns |
| At volume | A folder of thousands becomes one CSV in a pass | Falls apart past a handful of emails | One file at a time, still not parsed | Bulk but only whole-message text |
| Best for | A clean, consistent CSV to import anywhere | One or two one-off emails | It does not actually work | A rough archive of raw messages |
Capabilities reflect each approach as of July 2026. Built-in export features change, so verify current support before you rely on one. No pricing is implied here.
Frequently asked questions
How do I convert an email to CSV?
Paste the message, upload an EML or MSG file, or connect a mailbox in MailParse, then name the fields you want as columns. The parser decodes the MIME parts, reads the body and attachments, and writes one comma-separated row per email with your headers on top. You download the CSV and open it in Excel, Google Sheets, or any tool that imports CSV, with no copy and paste.
Can I export emails to a CSV file?
Yes. Connect a Gmail, Outlook, Microsoft 365, or IMAP mailbox, or upload the messages, and MailParse exports them to a single CSV file, one row per email. You choose which fields become columns, so the export holds the sender, date, subject, and the specific body values you name rather than a dump of every raw message.
How do I convert an email body to CSV?
Name the values you want pulled from the body, such as order_number, invoice_total, or tracking_number, and MailParse finds them in the text and returns each as its own CSV column. HTML tables in the body become CSV rows, so the data inside the message ends up as clean columns instead of one long block of text in a single cell.
How do I convert Outlook emails to CSV?
Connect your Outlook or Microsoft 365 account, or upload the saved MSG or EML files, and MailParse converts each message to a CSV row. Outlook has no built-in way to export the values from inside an email body to CSV, so the parser fills that gap by naming the fields and writing them to columns automatically.
How do I convert multiple emails to CSV at once?
Connect a mailbox or select all the files together, and MailParse writes every message into the same CSV, one row each. This is where copy and paste falls apart and a parser pays off: a folder of a few thousand emails becomes one combined file in a single pass, with consistent columns you can import straight into a sheet or database.
What is a CSV file used for?
A CSV file is a plain-text table where each line is a row and commas separate the columns, and almost every spreadsheet, database, and business tool will import it. That universality is why email data is worth converting to CSV: once your messages are in a CSV, you can open them in Excel or Sheets, load them into a database, or import them into accounting or CRM software.
How do I import the CSV into Excel or Google Sheets?
In Excel, open the CSV directly or use Data then From Text/CSV to control the delimiter; in Google Sheets, use File then Import and pick the CSV. Because MailParse writes proper UTF-8 with quoted fields, the columns land correctly instead of splitting on commas inside the text, so the sheet opens ready to sort and filter.
Is there a free way to convert email to CSV?
You can create a free account to paste a message and see the CSV it produces before committing. Paid plans add the volume, scheduled mailbox sync, and team access that ongoing workloads need. The manual free route, copying values into cells by hand, works for a couple of emails but costs more time than it saves once you are past a handful.
