What is inside an ODT file
An .odt file (OpenDocument Text) is the standard format for LibreOffice Writer and was
the default word-processor format for OpenOffice before it. Like a .docx, it is a ZIP
archive of XML files. The text lives in content.xml, wrapped in ODF namespace elements:
text:p for paragraphs, text:h for headings, text:list-item
for list entries.
Because the format is an open standard, any application that supports OpenDocument can produce an
.odt — LibreOffice, OpenOffice, Google Docs, Apple Pages, and many others. This extractor
reads the content.xml directly, without needing any of those applications installed.
How to extract text from an ODT file
- Open the document. Drop the .odt file onto the box above, or click to browse. Files from LibreOffice Writer, OpenOffice, Google Docs, and any OpenDocument-compatible application are supported.
- Read the extracted text. All body text appears with paragraph breaks preserved and headings marked. Tables are flattened to their text content in reading order.
- Copy or download. Copy the result to paste elsewhere, or download it as a .txt file.
What comes out
- All body text in document order, with paragraph breaks preserved.
- Headings at their real levels, marked with a # prefix so you can see the structure at a glance.
- List items with their nesting level.
- Table cell text in left-to-right, top-to-bottom order.
- Word count shown after extraction.
Which files work
Any .odt file from LibreOffice Writer, Apache OpenOffice, Google Docs (File → Download
→ OpenDocument Format), or any OpenDocument-compatible application works here. The ODF standard is
widely used in European governments, education, and organisations that cannot use proprietary formats.
For Word .docx files use the DOCX text extractor.
For the older binary .doc format, open it in LibreOffice and save as .odt or .docx first.
For RTF files use the RTF text extractor.
Why the document is never uploaded
An .odt is a ZIP archive, and the browser's own DecompressionStream unpacks it locally.
The content.xml inside is then parsed with the browser's own DOMParser. No network request
is made at any point after the page loads, and the file is gone when you close the tab.
LibreOffice is widely used in government and public-sector organisations for exactly this reason — the open format means no lock-in. Keeping extraction local extends that principle to processing too.
What is not extracted
- Formatting — bold, italic, font sizes and colours are stripped; only the text content survives.
- Embedded images — images are stored in the archive but are skipped here.
- Headers, footers and footnotes — these are not part of the main body text flow and are not included.
- Comments and tracked changes — annotation text is skipped.
- Frames and text boxes — anchored objects outside the main text flow are not included.
Who extracts text from ODT files
- Linux and open-source users — LibreOffice is the default word processor on most Linux distributions; ODT is its native format.
- Government and public-sector workers — many European governments mandate ODF for document interchange; ODT is common in official correspondence.
- People without LibreOffice — reading an ODT on a machine or phone with no office suite installed.
- Developers — getting document content into a pipeline, search index or CMS.
- Anyone feeding text to an AI tool — producing clean text to paste into a model that cannot read .odt directly.
ODT compared with DOCX
ODT and DOCX are both ZIP archives of XML, and both store paragraphs, headings, lists and tables
as XML elements. The difference is the XML dialect: ODT uses the OASIS OpenDocument namespace
(text:p, text:h) while DOCX uses the Office Open XML namespace
(w:p, w:body). Both formats are open standards — ODT under OASIS, DOCX under
ECMA — so both can be parsed without any proprietary library.
LibreOffice can open both formats; Word can open .odt since Word 2010. For DOCX files
use the DOCX text extractor. For RTF files use the
RTF text extractor.
Frequently asked questions
Can I open an ODT file without LibreOffice?
Yes — drop it onto this page. The file is read in your browser, so no LibreOffice, no OpenOffice and no software install is needed.
Is my ODT file uploaded to a server?
No. The file is unzipped and parsed entirely in your browser. Nothing is transmitted.
Does it handle files from Google Docs or Pages?
Yes. Google Docs and Apple Pages can export .odt, and those files use the same ODF standard that LibreOffice produces.
Does it preserve headings?
Yes. Heading levels are marked with # prefixes so you can see the document structure. Body paragraphs appear without markup.
Can it extract text from an ODS (spreadsheet) or ODP (presentation)?
Not yet — this tool handles ODT documents only. For Excel files use the Excel data extractor. For PowerPoint use the PowerPoint text extractor.
What about tables inside the ODT?
Table cell text is extracted in left-to-right, top-to-bottom order. The grid layout is not reconstructed — the cells come out as a flat sequence of paragraphs.
Does it work with older OpenOffice .odt files?
Yes. The OpenDocument format has been stable since ODF 1.0 in 2005. Files from any version of OpenOffice or LibreOffice extract correctly.
