View text files online
For a quick look at a README, JSON response, XML export, HTML snippet, or plain-text log, a full editor is often more friction than the file deserves. Drop it here for a clean local reading view.
Markup is shown as text, not rendered as a webpage. That means scripts and remote resources stay inert while search still works across the readable content.

How it works
Choose a supported document from your device. Its bytes are read directly by this browser tab.
The viewer selects the matching local parser: PDF renderer, spreadsheet grid, Office package reader, ebook reader, or safe text decoder.
Move between PDF pages, slides, document sections, or workbook sheets; search extracted text and spreadsheet values locally.
Clear the file when finished. The read-only preview is discarded from the tab and nothing has been uploaded.
What the tool does
- Real PDF page rendering with page navigation and zoom
- Read-only XLSX, XLS, XLSM, ODS, CSV, and TSV grids with sheet tabs
- DOCX, ODT, PPTX, and EPUB text reconstruction without running embedded content
- Safe plain-text viewing for TXT, Markdown, HTML, JSON, and XML
- Search across extracted document text or loaded spreadsheet cells
- Hidden and very-hidden spreadsheet sheets labelled for intentional review
- Macros, scripts, remote resources, forms, and embedded executables never run
How the result is verified
A preview is shown only after the relevant local parser accepts the file structure. PDF pages must render through PDF.js, spreadsheets must expose readable sheets, Office and ebook packages must contain their required document parts, and text is decoded as inert content. Reconstructed layout limitations remain explicitly labelled.
Frequently asked questions
Will HTML or JSON run when I open it?
No. The viewer decodes the file and displays inert text. Scripts, styles, forms, and remote resources are not executed.
Which text formats can I view?
The viewer accepts TXT, MD, Markdown, HTML, HTM, JSON, and XML files and gives each one the same private, searchable text preview.
