Documents
Document remediation covers PDF, Word, PowerPoint, Excel, and LaTeX source. It ships in github.com/Aelira-AI/aelira-core — nothing on this page is a hosted-only feature.
Where documents sit
Documents is one of four equal pillars in Aelira, alongside LMS integrations, web page scanning, and media. They cooperate through a shared scan model and findings format while each pillar can run independently.
Coverage by format
This table is the boundary of what the document pipeline does today. Formats outside it are not handled, and remediation is in beta: output is a proposal for human review, never a signed-off document.
| Format | Checks | Can change | Human decision | Detail page |
|---|---|---|---|---|
| Tag structure, reading order, alt text presence, text layer on scanned pages, table structure. | May update metadata and bookmarks and apply eligible structure, heading, list, table, and figure alt-text changes when the file exposes a safe target. | A person reviews OCR output, proposed alt text, and reading-order findings to verify that they match the page and its intended semantics. | PDF remediation | |
| DOCX | Heading hierarchy, images and alt text, tables, fake lists, link text, language and title, SmartArt, and embedded objects. | May set eligible image alt text, apply heading styles, convert fake lists to list formatting, mark first-row headers, replace targeted link text, and set language and title. | Whether the resulting semantics express the author’s intent; SmartArt and embedded objects remain manual review and are not rewritten. | This page |
| PPTX | Image alt text, text/background contrast, slide titles, optional image-of-text OCR, and animation and media signals. | May set eligible image alt text, adjust text colour when foreground/background data is available, and add missing slide titles. | Reading-order findings produce guidance for manual review; Aelira does not structurally reorder shapes. Images of text and media captions or transcripts also remain review work. | PowerPoint scanner |
| XLSX | Sheet names, table and header structure, chart and image alternatives, merged cells, colour-only cues, frozen panes and navigation, pivot tables, and conditional formatting. | May rename a generic sheet, format or create a table with a first-row header, add a missing chart title, append text indicators for recognized colours, and freeze panes. | A person verifies inferred ranges and headers, chart-title meaning, colour semantics, formulas, pivots, and package fidelity. | This page |
| LaTeX | Document metadata, language declaration, figures, tables, equations, link text. | Preserves the .tex source and may improve metadata, language declaration, figure descriptions, table structure, equation output as MathML with ARIA labels, and link text. | Mathematical intent — a well-formed ARIA label can still describe the wrong thing. | LaTeX and MathML |
Word and Excel
DOCX, PPTX, and XLSX share the OOXML family but use separate processors, remediators, routes, and evidence. Word and Excel details stay here until dedicated pages exist.
Word (DOCX)
Checks heading hierarchy, images and alt text, tables, fake lists, link text, language and title, SmartArt, and embedded objects. Eligible changes include image alt text, heading styles, list formatting, first-row headers, targeted link text, language, and title. Semantics, SmartArt, and embedded objects remain human review work.
Excel (XLSX)
Checks sheet names, table and header structure, chart and image alternatives, merged cells, colour-only cues, frozen panes and navigation, pivot tables, and conditional formatting. May rename a generic sheet, format or create a table with a first-row header, add a missing chart title, append text indicators for recognized colours, and freeze panes. Recognized-colour text indicators can change cell text or value presentation. A person verifies inferred ranges and headers, chart-title meaning, colour semantics, formulas, pivots, and package fidelity.
Command and interface details for these formats live in the repository documentation, which tracks the code. This page does not restate them so the two cannot drift apart.
Human review is part of the pipeline
- Fixes are confidence-scored. Deterministic ones clear the threshold on their own; AI-generated ones, including alt text, are flagged for a reviewer to accept, edit, or reject.
- If a source cannot be read, the issue stays open and is flagged for human review. Placeholder or invented text is never written in its place.
- Re-scanning a remediated file is the evidence step: it shows which findings closed and which remain open.
- Whether a document meets a standard is a determination the institution makes. The tooling produces findings, fixes, and re-scan results.
