EML to Excel Converter: Convert EML Files to Excel, CSV and JSON
Turn .eml email files into a clean Excel spreadsheet, no Outlook needed
MailParse converts .eml email files into structured Excel, CSV, and JSON. Drop in a single message or a folder of thousands, pick the fields you want as columns, and get a spreadsheet with every sender, date, subject, body, and attachment in place. It runs in your browser on Mac, Windows, or Linux, so there is no Outlook and no desktop install to wrestle with. Drop a .eml file below to see the columns it pulls out.

An .eml file is a single email saved in plain-text MIME format, so Excel cannot open one directly: it shows headers and encoded blocks rather than columns. To convert EML to Excel, run the files through a parser that decodes the MIME structure and writes each message as a row. MailParse takes one .eml or a whole batch and returns an .xlsx, CSV or JSON file with date, sender, recipients, subject and the fields you name from the body.

An EML file is a single email saved in the standard MIME format, the same format Apple Mail, Thunderbird, and most webmail clients use when you export or save a message. Gmail, Outlook on the web, and Yahoo all let you download a message as a .eml file, and a bulk export of a mailbox often lands as a folder full of them. Each .eml holds the sender, recipients, date, subject, full body, headers, and any attachments as plain text and base64. That is fine for reopening one message. It falls apart when you have a folder of 4,000 of them and finance, legal, or ops needs the data lined up in columns.
MailParse reads .eml files and writes the fields you care about into rows and columns. Upload the files you already have, or connect your mailbox to pull messages straight in. You pick which fields become columns, including custom values like an invoice number, order ID, or tracking number buried in the body, and download the result as a real Excel workbook (.xlsx), a CSV for any spreadsheet, or JSON for a database or API. The whole job runs in your browser, so there is no Windows-only converter to install and Outlook does not need to be involved at all. This page covers how to convert EML to Excel, how to batch convert a whole folder, how to open an EML file in Excel the right way, and why a web converter beats the copy-and-paste and Insert Object tricks that lose half your data. If you have tried the direct route already, can you open an EML file in Excel explains exactly why the raw file comes out unreadable. If your export landed as Outlook .msg files instead, the MSG to Excel converter handles that format and converting MSG files to Excel walks through it step by step, and converting EML files to CSV in bulk covers a folder of several thousand messages end to end. If the messages are still sitting in a live mailbox rather than exported to disk, connecting it with email to Excel skips the export step entirely.
What the EML to Excel converter does
Everything you need to turn a pile of .eml files into one clean spreadsheet.
No Outlook, no install
Outlook does not even open .eml files cleanly, and most EML converters are Windows-only downloads. MailParse runs in any browser on Mac, Windows, or Linux, with nothing to install.
Batch convert whole folders
Drop in thousands of .eml files or a zipped folder and get one combined spreadsheet, with each email as its own row. There is no per-file limit on a job.
Excel, CSV, or JSON
Export a formatted .xlsx Excel workbook, a clean .csv for any spreadsheet, or JSON for a database or API, not one rigid layout you then have to reshape by hand.
Custom field extraction
Pull a tracking number, invoice total, or order ID out of the message body into its own column, not just the standard sender, date, and subject headers.
Nothing lost in conversion
Sender, recipients, CC, BCC, date, subject, full body, and attachment names all come through, with Unicode and emoji intact and HTML tables read as rows.
Private by design
Conversion runs over an encrypted connection and your source files are deleted after processing. Your email is never used to train AI.
How to convert EML files to Excel or CSV
Four steps from a folder of .eml files to a single spreadsheet.
Add your EML files
Upload .eml files (a single file, a multi-select, or a zipped folder), or connect your mailbox to pull messages in automatically.
Choose your columns
Tick the standard fields you want, then add any custom fields to pull from the message body, like an order ID or invoice total.
Pick a format
Select Excel (.xlsx), CSV, or JSON depending on where the data is going next.
Download the spreadsheet
Get one clean file with every email as a row. Save the column setup and re-run it any time new .eml files come in.
Who converts EML files to a spreadsheet
Teams that get handed folders of exported .eml messages and need the data in columns.
Legal & e-discovery
Convert exported case mailboxes into a reviewable spreadsheet with sender, date, subject, and body columns for filtering, review, and production.
Accounting & AP
Turn folders of saved invoice and receipt .eml files into an Excel sheet with vendor, amount, and due date columns ready for reconciliation.
Email migration & archiving
Flatten an exported .eml archive into a single searchable spreadsheet before switching systems or closing out a mailbox.
Sales & operations
Extract orders, leads, and shipping notices from saved emails into a spreadsheet your team can sort, filter, and report on.
Why a web EML converter beats the manual methods
Bulk, not one at a time
Copy-and-paste from Notepad and Excel's Insert Object trick handle one .eml at a time. MailParse converts a whole folder in a single pass, one row per email.
No data loss
Manual methods drop fields and mangle HTML bodies. MailParse keeps every header, the full body, and attachment names mapped to clean columns.
Mac and Linux, not just Windows
Almost every EML to Excel converter is a Windows-only download. MailParse runs anywhere you have a browser, including Mac and Linux.
Custom fields, not just headers
Desktop converters export fixed columns like sender and subject. MailParse also pulls values out of the body, such as an invoice total or order number.
Frequently asked questions
How do I convert an EML file to Excel?
Upload the .eml file to MailParse, select the fields you want as columns (sender, date, subject, body, and any custom fields), choose Excel as the output, and download the .xlsx. Each email becomes one row, and you can add as many .eml files as you like in a single job to build one combined workbook.
How do I convert multiple EML files to Excel at once?
Select all the .eml files together or upload a zipped folder, and MailParse writes every email into the same spreadsheet, one row per message. There is no per-file cap on a job, so you can batch convert a handful or several thousand .eml files in one pass and get a single combined Excel file.
Can you open an EML file in Excel?
Not directly. Excel cannot read the MIME structure of a .eml file, so opening one shows raw headers and encoded text. You first convert the .eml file to CSV or .xlsx, which maps each field to a column, and then Excel opens it cleanly as a normal spreadsheet with the email data in rows.
How do I open an EML file without Outlook?
Upload the .eml file to MailParse in your browser and convert it to Excel, CSV, or JSON. Because the .eml format is plain MIME text, MailParse reads it directly without Outlook or any email client installed, so you see the contents and get the data in columns at the same time, on any device.
How do I convert EML to CSV?
Add your .eml files to MailParse, pick the columns you want, choose CSV as the output, and download the result. Every message becomes a row in the CSV, which opens cleanly in Excel, Google Sheets, or any spreadsheet app, and you can convert one file or a whole folder in the same pass.
How do I convert an EML file to Excel on a Mac?
Macs have no built-in way to turn .eml files into a spreadsheet, and most EML converters are Windows only. Upload the .eml file to MailParse in your browser instead and convert it to Excel, CSV, or JSON, which any Mac app opens, with no Outlook and no Windows machine needed.
Will I lose any data when I convert EML to Excel?
No. MailParse keeps the sender, recipients, CC, BCC, date, subject, full body, and attachment names, mapping each to its own column, with Unicode and emoji preserved and HTML tables read into rows. Unlike copy-and-paste from Notepad, nothing is dropped or truncated in the process.
