URLs without Markdown syntax ## Validation - URL syntax validation - Duplicate link detection - Broken reference link detection - Unused reference definition warnings ## Output Provides comprehensive statistics including: - Link counts by type - Unique vs duplicate URLs - Internal vs external links - Anchor/fragment detection - Issue reporting for broken or invalid links ## Inputs - **Markdown Content** (textarea): Paste your Markdown content here to extract links... - **Link Types to Extract** (select) - **Validate URL Syntax** (checkbox) - **Find Duplicate Links** (checkbox) - **Sort Results By** (select) - **Extract Anchor/Fragment Identifiers** (checkbox): Count and track links with # anchors ## When to use - When auditing Markdown documentation to identify broken, duplicate, or invalid links. - When preparing Markdown content for migration to another platform or format, requiring a full link inventory. - When analyzing link structures in Markdown files for SEO optimization or maintenance tasks. ## How it works - Input your Markdown content via the text area or file upload option. - Select the types of links to extract, such as inline, reference, bare URLs, images, or autolinks. - Configure validation settings like URL syntax checking, duplicate detection, and anchor extraction. - Receive a JSON output with extracted links, counts by type, validation results, and any detected issues. ## Use cases - SEO auditing of Markdown-based websites to find and fix broken or duplicate links. - Content migration projects to extract all links for updating references in a new system. - Documentation maintenance to validate reference links and ensure consistency across files. ## Frequently asked questions ### What link types are supported for extraction? The tool extracts inline links, reference links, bare URLs, image links, and autolinks from Markdown content. ### How does URL validation work? It checks the syntax of URLs to ensure they are properly formatted, but does not verify if the URLs are accessible or live. ### Can I extract only specific link types? Yes, you can select which link types to include using the 'Link Types to Extract' multi-select option. ### What output format is provided? The output is in JSON format, including link details, statistics, and validation reports for easy parsing. ### Is there a limit on the input size? The tool handles typical Markdown documents, but very large files may impact processing time and performance. ## Related tools - [Blood Gas Acid-Base Interpretation (AG / ΔAG)](https://elysiatools.com/en/tools/blood-gas-anion-gap): Complete ABG analysis: pH, primary disorder, compensation (Winter's formula), anion gap ± albumin correction, delta ratio for mixed disorder detection.

Adult reference ranges: TSH 0.4–4.0 mIU/L, FT4 0.8–1.8 ng/dL (≈10–23 pmol/L), FT3 2.3–4.2 pg/mL (≈3.5–6.5 pmol/L). High TSH + low FT4 → overt primary hypothyroidism; high TSH + normal FT4 → subclinical hypothyroidism; low TSH + high FT4/FT3 → overt primary hyperthyroidism; low TSH + normal FT4 → subclinical hyperthyroidism, exogenous hormone, or resolving thyroiditis (check FT3 for T3 toxicosis); low/normal TSH + low FT4 → central hypothyroidism; high TSH + high FT4 → TSH-secreting adenoma or thyroid hormone resistance. Low FT3 with normal TSH/FT4 indicates low-T3 (non-thyroidal illness) syndrome. Units selectable for TSH, FT4, FT3. Derived from ATA 2014/2016, NACB 2002, Garber 2012, and MDCalc.
