What is a .RELS file?
.RELS is a file format that Analyser can open and analyse in your browser.
- Did you know
- A .rels file is the relationships map inside an Office Open XML package, listing how the parts of a DOCX, XLSX or PPTX link together.
- It lives in a hidden _rels folder within the ZIP and points each document part at its images, styles and other resources by ID.
- The same relationships mechanism comes from the Open Packaging Conventions, which also underpin XPS, 3MF and NuGet packages.
- What Analyser shows you
- Open lightweight document and markup formats as selectable page previews: Rich Text Format (RTF, control words stripped to readable prose), AbiWord (ABW), FictionBook e-books (FB2), Hangul HWPX, and MHTML web archives (the saved HTML rendered with scripts removed), plus markup and typesetting source - DITA, TEI, JATS journal XML, reStructuredText, AsciiDoc, Org-mode, Textile, TeX/LaTeX and BibTeX - shown with every page selectable and copyable. Also opens the small sidecar files unpacked from 3MF and OOXML bundles: OPC relationship XML (.rels) and MD5 checksum text (.md5).
- Open a .RELS file
- Drag a .RELS file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
