About this tool
Convert HTML markup into a JavaScript, PHP, JSP, Perl or VB.NET string you can paste into code, with quotes and line breaks escaped.
Pick the language, paste your HTML and copy the escaped string. This page brings together 5 separate html to code converter pages (JavaScript, JSP, Perl, PHP, VB.NET) so you can compare them without hunting for the right one.
Open HTML to Code Converter on AltFTool — it loads instantly in your browser.
Choose your language at the top: JavaScript, JSP, Perl, PHP and 1 more. On a phone it is a drop-down list.
Fill in the html to code converter for that language; each of the 5 options keeps its own rules, data and defaults.
Read the result, then switch language to compare. The page link keeps your language (?v=javascript), so you can bookmark or share it.
JavaScript, JSP, Perl and the rest sit behind one picker, so switching language takes a tap instead of a new search.
Every language keeps its own rules, numbers and defaults rather than one generic template.
The link remembers the language you picked, so a bookmark or a shared link opens straight on it.
5: JavaScript, JSP, Perl, PHP, VB.NET. Pick one at the top of the tool; the page link updates (for example ?v=javascript) so you can bookmark or share that exact view.
Paste it and switch to HTML to JS: the markup is wrapped in a template literal as const html = `…`, with backticks, backslashes and ${ escaped so the string stays valid. You also get the mount snippet that assigns it to document.querySelector("#app").innerHTML.
Paste the HTML and run HTML to JSP. Placeholders such as {{user.name}} become ${user.name}, root-relative asset paths gain the ${pageContext.request.contextPath} prefix, and two directives are added at the top: the page directive with contentType text/html; charset=UTF-8 and the JSTL core taglib bound to prefix c.
It uses a double-quoted heredoc: print <<"HTML"; followed by your markup and a closing HTML line. Double quotes are deliberate, because that is what allows $scalar interpolation inside the block; if the terminator word already exists on its own line in your markup, the tool switches to HTML_BLOCK to avoid closing the block early.
htmlspecialchars($var, ENT_QUOTES, 'UTF-8') on every placeholder. ENT_QUOTES is the flag that escapes both double and single quotes — the default would leave ' untouched, which is exactly the gap that breaks single-quoted HTML attributes — and naming UTF-8 explicitly avoids relying on the server's default charset.
It opens with <%@ Page Language="VB" AutoEventWireup="false" %>, followed by a <script runat="server"> block holding one Protected name As String = "..." line per placeholder, then your markup with <%= Server.HtmlEncode(name) %> in place of each {{ }}. Both the directive and the server block are optional toggles.
