Frequently Asked Questions

Online Viewer Tools is a small collection of browser-based file viewers for CSV, SVG, and XML files. Each viewer is focused on opening, inspecting, formatting, previewing, or exporting the file type it supports.

The site currently includes CSV Viewer Online, SVG Viewer Online, and XML Viewer Online. Other file viewers may be added when they can provide a useful browser-based result with clear limits.

No. The tools run in a modern browser and do not require registration, browser extensions, or desktop software.

The CSV, SVG, and XML viewers are designed around local browser processing. Files are read by the page in your browser for the viewing task. Avoid opening sensitive files in any online tool unless you have reviewed the privacy policy and your own security requirements.

No. The SVG preview is rendered in a restricted sandbox frame, and the tool warns when it detects script tags, event handlers, or external references. It is a viewer and inspection helper, not a script runner.

It can open typical browser-sized CSV files and warns when a file is large. Very large datasets may be better handled by a database, spreadsheet program, or a dedicated desktop data tool.

Yes. The CSV viewer supports table search, column sorting, light cell editing, page-size controls, CSV export, and JSON export.

Yes. You can preview SVG markup and export a PNG from the rendered SVG when the browser can load the markup as an image.

The XML viewer checks whether XML is well formed and reports parser errors from the browser. It does not perform schema validation against XSD or DTD rules.

Yes. The XML viewer provides formatted output, minified output, a tree view, and search across element names, attributes, and text values for quick inspection.

Those formats may be added later if they can be previewed or inspected reliably in a browser. STL needs dependable 3D viewing, ZPL needs printer-language preview accuracy, and EPS needs careful handling because browser-native support is limited.
