Convert ODT to TXT Online for Free

Plain Text Has Characters and Lines, Not a Page Layout

An .odt is a structured OpenDocument Text package, not a stream of visible characters. ODF 1.3 packages are ZIP files with XML and related parts: a typical file has content.xml for document content and automatic styles, styles.xml for styles, and a required META-INF/manifest.xml that lists package entries and media types. Pictures, metadata, settings, fields, tracked changes, page styles, and objects can be separate parts. The program opening an ODT uses all of that information to decide where text appears on a page and how it behaves when edited.

A TXT file has no comparable document package. It is simply a sequence of bytes interpreted as characters, with line-ending characters to divide it into lines. It has no inherent page size, font, bold text, heading level, image placement, table grid, margin, header, footer, revision record, or hyperlink target. A converter can extract the words and arrange paragraphs as lines, but it cannot store the original visual system in ordinary plain text. This is intentional, not a low-quality version of a word-processing file.

TXT is useful when the destination needs just the written material: a simple text editor, a command-line tool, a software import, source control, a searchable record, or an old system that rejects office packages. It is the wrong choice when the form of the document carries meaning. If a table's columns, a heading hierarchy, footnotes, redlines, image captions, or a signature area matter, keep an ODT or make a PDF/DOCX copy for that purpose. Treat TXT as a content extraction, not as a page-preserving conversion.

What an ODT-to-TXT Export Intentionally Removes

The exporter reads the text represented by the ODT and emits character data with paragraph breaks. What it must leave behind is just as important. Character formatting such as bold, italic, color, typeface, font size, background, and underlining has nowhere standard to go. Paragraph styles and heading styles become ordinary text unless the exporter adds its own nonstandard marks. Tables become a sequence of cell contents separated by whitespace, tabs, or line breaks; a text reader does not know their original column widths, merged cells, borders, or header rows. Images, diagrams, embedded spreadsheets, and drawing objects cannot be represented as pictures in a plain-text stream, so at most a converter can omit them or replace them with textual labels.

The same applies to document behavior. A hyperlink can remain as visible link text, but TXT has no native link destination. Footnotes and endnotes may become inline text or be placed elsewhere, depending on the exporter. Fields such as page number, date, table of contents, and cross-references may export their displayed value but not their updating rule. Comments and tracked changes are especially risky because plain text has no revision model. Before conversion, decide whether the desired output is the final visible text, the text with review annotations, or a human-readable record with labels. A plain text file cannot answer that question on its own after the document structure has been discarded.

This loss can be a benefit. A TXT file has no office-format macros, no embedded image payloads, and no hidden layout instructions. It is small, easy to compare line by line, and readable in tools that do not understand ODF. The trade-off is absolute: plain text retains characters and line breaks, while the meaning conveyed by layout must be rewritten into the characters themselves if it is needed. A label such as “Table 1 — Values follow” is more durable in TXT than relying on an invisible table structure that is no longer there.

The Benefits and Costs of a Text-Only Copy

• Almost any device can inspect the words. Plain text needs only a character encoding, while an ODT requires an ODF-aware application to understand the package.
• The file can be much smaller. Images, fonts, document metadata, styles, and package entries are not carried into a basic text stream.
• Formatting is not preserved. Bold, heading levels, margins, and page breaks are not TXT features, so the text must stand on its own without visual cues.
• Character encoding becomes a visible decision. UTF-8 handles the ASCII range directly and can represent Unicode text, but a receiver that assumes a legacy code page can still show the wrong characters.
• Line ending choice affects tools. LibreOffice's Text Encoded export offers CR & LF, CR, and LF paragraph breaks; use the convention the receiving program expects rather than treating them as interchangeable.

The safe workflow is to save the original ODT, create the TXT copy, and inspect that copy in the actual destination program or import process. A text editor showing a legible file proves only that its own encoding and newline rules were compatible. It does not prove that a database importer, an older application, or an automated parser will interpret the same bytes the same way.

Encoding and Line Break Choices Determine Whether Text Travels

A character is an abstract symbol; an encoding is the byte sequence used to store it. UTF-8 is usually the most useful TXT choice because the US-ASCII characters U+0000 through U+007F use the same single-byte values 00 through 7F, while UTF-8 also represents characters outside ASCII with multi-byte sequences. RFC 3629 records this ASCII compatibility and the way UTF-8 identifies multi-byte sequences. That does not make UTF-8 self-explaining to every old program. A program that reads UTF-8 bytes as Windows-1252 or another legacy encoding can turn accented letters, non-Latin scripts, and typographic punctuation into unrelated symbols.

LibreOffice exposes this choice in its ASCII Filter Options for the “Text Encoded” format. For export, it lets you choose the character set and paragraph break. It also lets Unicode exports include a byte-order mark (BOM). A UTF-8 BOM is the byte sequence EF BB BF; RFC 3629 explains that UTF-8 does not need byte order, because it uses one-byte encoding units. LibreOffice explicitly warns that a UTF-8 BOM is optional and can cause problems with some legacy software. Use it only when the receiving application needs that signature to recognize UTF-8. Do not add it by habit to data meant for a parser that treats the first three bytes as part of the first field or first word.

Line endings are bytes too. LibreOffice offers CR & LF as the default, CR, or LF. CR is U+000D and LF is U+000A. Many Windows-oriented tools expect CRLF, while Unix-like tools commonly use LF; particular import rules can be stricter than the operating system. RFC 5198 specifies CRLF for its Net-Unicode interchange profile, but that profile is not a universal rule for every local text file. Match the destination specification. If there is no specification, UTF-8 without BOM and the local tool's normal line-ending convention are reasonable defaults, followed by an actual import test.

Failures That Appear After an ODT Becomes TXT

Accented or non-Latin characters become question marks or nonsense. This is usually an encoding mismatch, not damage to the visible ODT. LibreOffice notes that its text export has a character-set setting, and its support forum points out that ODT is Unicode UTF-8 while non-Unicode encodings can exclude scripts they cannot represent. Export UTF-8 when the destination accepts it, avoid a BOM unless it is required, then reopen the file with UTF-8 selected. If the receiver requires a named legacy code page, confirm that every needed character exists in that code page before converting.

All text appears as one line, or every line has an extra blank line. The receiver is probably applying a different newline interpretation from the exporter. Choose CRLF, CR, or LF deliberately in LibreOffice's Text Encoded export. Inspect the file in the actual tool, especially when it is sent to a script or an older program. Changing the file extension cannot change a bare LF into CRLF or teach a parser to recognize an unexpected separator.

Tables and columns collapse into confusing runs of words. TXT has no column width or merged-cell model. Tabs may appear aligned in one editor but vary with tab-stop settings in another. Export the data in a delimiter-based format when it is truly tabular, or rewrite the table as labeled lines. Do not rely on a page screenshot's visual spacing surviving a plain-text extraction.

Unexpected breaks appear within sentences. LibreOffice documents that copied text can contain unwanted line breaks and provides an AutoFormat method to combine single-line paragraphs. Clean those breaks in the source when they are editorial errors; otherwise the TXT export will faithfully preserve a division that may not make sense outside the original page layout.

ODT and TXT: What the File Can Still Know

Questions to Settle Before Saving Plain Text

Will TXT keep bold headings, images, and tables?
No. Plain text has no standard format for those features. It retains characters and line breaks; rewrite essential labels into the text or use a document format that stores structure.

Which encoding should I choose?
Use UTF-8 when the receiver supports it. It preserves ASCII byte values and represents a broad range of Unicode characters. Confirm the destination's requirement if it names a legacy code page.

Should a UTF-8 TXT file include a BOM?
Only if the receiving program asks for or needs it. LibreOffice says it is optional and can upset legacy software; a BOM is not required for UTF-8 byte order.

Why does my TXT look different in another editor?
Check both encoding and line breaks. A reader using the wrong character set or expecting CRLF rather than LF can display broken characters or lines even when the exported bytes are intact.
