MSG File

File extension	.MSG
Category	Document File
Description	MSG file is a MS Outlook email saved to a separate file. Such mail format is also used in The Bat!, Windows Mail, MDaemon, etc. It contains email fields and attachments, supporting both plain text and HTML mail formatting. As a rule, the mail content is encoded by base64 scheme. Encoding is required for mail to pass the mail servers that originally process text only. MSG can be opened in the program version it was created in, and the file will conflict with all other applications. To convert .MSG to PDF, HTML, TXT or other formats use the online converter.

TXT File

File extension	.TXT, .TEXT
Category	Document File
Description	TXT format is the simplest text file standard that doesn’t support formatting. Such file contains text characters, tab and line feed characters. Being outdated in functionality it has one major advantage - compact file size, comfortable for sharing, data export/import. It supports various charsets (DOS, WIN, ISO, KOI-8). The charset can be changed to make TXT file compatible with any text reader. The lack of formatting is solved by setting up format params in the reader program.

We feed extracted email text into our NLP pipeline for sentiment analysis — converting a folder of MSG files to plain text with this tool cut our preprocessing time from hours to minutes.

Our search indexer only accepts plain text, so we use this to convert incoming MSG archives before ingestion. Consistent output format makes tokenization straightforward downstream.

For compliance text export we needed clean, stripped-down TXT files from thousands of MSG emails — the batch conversion handled our entire archive without a single error.

MSG to TXT Converter — Frequently Asked Questions ▼

What is an MSG file?

MSG is Outlook's per-email format, built on the Compound File Binary Format. Each .msg file holds one message — headers, body, recipients, attachments — packed into an opaque binary container that only Outlook and a few specialised tools can read.

How do I convert MSG to TXT online?

Upload your .msg file using the button above. The converter parses the OLE compound structure, extracts the plain-text body and the header block (From, To, Subject, Date), and returns a downloadable .txt file you can search, index, or paste anywhere.

What about HTML emails?

The converter prefers the plain-text body if the MSG contains one. If only the HTML body is present, the converter strips the HTML tags and keeps the visible text. The result is clean prose suitable for grep or NLP.

Are attachments included?

Attachments are listed by filename at the bottom of the text file. The binary attachment contents are not embedded in a plain-text file. To extract attachments as separate files, use the desktop Total Outlook Converter.

Will the headers stay readable?

Yes. The converter writes a short header block at the top of the TXT — From, To, Cc, Subject, Date — followed by a blank line and then the body. This is human-readable and machine-parsable.

What is the maximum file size?

The online converter accepts MSG files up to 50 MB. Most emails are well under 1 MB. The limit matters only for messages with very large attachments.

Are my uploaded files kept private?

Files are deleted automatically after you download the TXT. They are not stored or shared. For confidential email, run the conversion locally with Total Outlook Converter.

Convert MSG to TXT — Outlook Email as Searchable Plain Text

MSG is a binary Outlook file — opaque to grep, full-text indexers, and most scripting languages. Converting MSG to TXT strips out the OLE structure and gives you a clean text file with the headers and body, ready for command-line search, log ingestion, or NLP pipelines. Drop your .msg file above.

What Is MSG?

MSG is Outlook's per-email format, based on the Compound File Binary Format (CFBF / OLE2). Each .msg file holds headers, plain-text and HTML bodies, recipients, attachments, and Outlook-specific properties packed into a binary container. The format is opaque to grep, Spotlight, and most non-Outlook tools — you cannot search the content directly with file-system tools.

What Is TXT?

TXT is the simplest possible document format: plain Unicode characters and line breaks, nothing else. Every operating system, every programming language, every editor, and every tool reads .txt without any plugin. Plain text is searchable by grep, indexable by Elasticsearch or Lucene, processable by Python and PowerShell, and is the format of choice for NLP and LLM input.

MSG vs TXT — Format Comparison

Property	MSG	TXT
Year	1997 (Outlook 97)	1960s (ASCII)
Container	Binary OLE compound	Plain Unicode
Grep-friendly	No (binary)	Yes
Full-text indexing	Requires Outlook hooks	Any indexer
NLP / LLM input	Needs extraction first	Ready to use
Formatting	HTML / RTF / plain	None
Typical use	Outlook storage	Search, scripting, archive

When Do You Need MSG to TXT Conversion?

Search through thousands of saved emails with grep, ripgrep, or PowerShell Select-String
Ingest email content into a log-analysis or e-discovery platform
Feed cleaned email text into an LLM prompt or NLP pipeline
Archive Outlook correspondence in a format that will survive every software change
Quote the body of an email in a system that accepts no formatting (chat, SMS, plain log)
Build a full-text search index across a historic mail archive without Outlook installed

Command-Line Conversion

Batch-convert an entire folder without opening the interface:

TotalOutlookConverter.exe C:\msg_files C:\txt_out /ConvertTo txt /ProcessRecursively

Add /ProcessRecursively to include subfolders. Save the command in a .bat file for scheduled or automated runs.
