About Sitemap Generator
What this page solves
Sitemap Generator solves the privacy and friction problem of typical online tools — it never uploads, never asks for a signup, and runs in your browser.
Sitemap Generator is a free developer utility that lets you generate xml sitemaps for your website directly in your browser. It is designed for everyday engineering tasks: debugging API responses, sanitizing payloads, validating data structures, generating test inputs, or transforming code between formats. Because every operation runs client-side in JavaScript, none of your code, tokens, or proprietary data is ever transmitted to a server — making Sitemap Generator safe for production credentials, internal schemas, and confidential snippets. Sitemap Generator loads as a small bundle and is interactive within a second on mid-range phones, so it is practical to use it from a phone while away from a desk. Nothing you load into Sitemap Generator is uploaded: the file or text is read with the browser's own FileReader and processed in page memory, so the work finishes even if your connection drops mid-task. For pair programming, screenshotting Sitemap Generator's output is cleaner than sharing a terminal scrollback — colleagues see exactly the data, not your shell prompt or env vars. It is part of our Developer Tools collection, which covers formatters, converters, validators, and generators for the languages and protocols you actually use. If you also need a complementary utility, try our JSON Formatter. Sitemap Generator is free, requires no signup, and works the same on macOS, Windows, Linux, and ChromeOS — perfect for quick fixes between IDE sessions or for sharing a reproducible workflow with teammates.
Common Use Cases
- Debug and inspect API responses during local development
- Validate and reformat data before committing it to a repository
- Convert between common developer data formats without installing CLI tools
- Share a reproducible transformation step with teammates via a URL
- Process sensitive payloads safely without uploading them anywhere
- Use as a quick scratchpad alongside your IDE or terminal
- Handling a one-off task on a borrowed or public machine where installing software is not an option
- Comparing two payloads field-by-field after a deploy to spot regressions
- Processing work files that company policy forbids uploading to external services

Frequently asked questions
Does a sitemap guarantee my pages get indexed?
No. It helps Google discover URLs, particularly on large sites or pages with few internal links. Whether a page is indexed depends on whether Google judges it worth indexing. Plenty of sitemap-listed pages sit in "crawled — currently not indexed" indefinitely.
Do priority and changefreq matter?
Barely. Google has said publicly it largely ignores both, because site owners set everything to high priority. An accurate lastmod date is worth more than either, since it genuinely influences recrawl scheduling.
Should I include every page?
Only pages you want indexed. Including noindex pages, redirects or duplicates sends contradictory signals — you are asking Google to index something you have told it not to index. Keep the sitemap aligned with your indexing intent.
How often should I update it?
Whenever pages are added or removed. If your build generates it automatically, that happens for free. A stale sitemap listing pages that no longer exist wastes crawl budget on 404s.
How to use Sitemap Generator?
1) Open the tool. 2) Enter or upload your input. 3) Get your result instantly. Everything happens locally — nothing is uploaded.
When should I use Sitemap Generator?
Use Sitemap Generator whenever you need a fast, private, browser-based way to generate xml sitemaps for your website.
Is Sitemap Generator safe?
Yes. Sitemap Generator runs 100% in your browser. Inputs are never uploaded, stored, or logged — safe for confidential content.
Will quality be affected by Sitemap Generator?
Sitemap Generator performs lossless operations — your content is not re-encoded or downgraded.
What formats does Sitemap Generator support?
Sitemap Generator supports JSON, YAML, XML, CSV, TOML and other developer-friendly text formats
Is Sitemap Generator free?
Yes — Sitemap Generator is completely free, with no registration, no watermarks, and no usage limits.
Is Sitemap Generator safe for sensitive data like API keys or tokens?
Yes. All processing in Sitemap Generator happens locally in your browser. No request is sent to any server, so credentials and proprietary code remain on your device.
Does Sitemap Generator work offline?
After the page loads, Sitemap Generator runs entirely in JavaScript and does not need a network connection for its core operations.
Can I integrate Sitemap Generator into a CI pipeline?
Sitemap Generator is a browser-based utility. For automation, use the equivalent open-source library — but for one-off debugging it remains the fastest option.
