Guides
Each converter has a page that tells you what it does. These are for the part after that — the file that came out wrong, and why.
One guide per tool, plus one on keeping the file off the network — all written from the questions people actually send in. No sign-up, and every page links straight to the converter it's about.
Markdown tables to HTML tables
Pipe tables become real <table> markup with <thead> and th scope attributes. Here's how to write the alignment row, what happens to it in the HTML, and why a table can come out as one long line of text.

What survives when Word becomes HTML
Which parts of a .docx come through as HTML and which are dropped on purpose. Headings, tables, lists and images survive as structure; fonts, colours and page layout don't. Here's how to tell them apart before you convert.

Getting clean HTML out of a Google Doc
Copying from a Google Doc gives you HTML full of c1 and c17 class names, a font-weight:normal <b> wrapper and google.com/url redirects on every link. Here's what each one is and how to get rid of all of them.

Blank lines and paragraphs in HTML
A blank line in your text starts a new paragraph, but empty lines in HTML source collapse — the browser ignores them. How blank lines become <p> tags, when to use <br>, and how single newlines and bare URLs are handled.

CSV to an HTML table, including the big ones
How the delimiter is detected, what happens to quoted fields and embedded newlines, why a one-column file reports a delimiter problem, and what the 100,000-cell limit means in practice.

Excel to HTML: formulas and formatting
Formulas convert to their calculated values, not the formulas themselves — and there's one case where they come out empty. Plus what happens to currency formats, dates, merged cells and multiple sheets.

Word to HTML, built in your tab and shown in a sandbox
The document becomes HTML inside this tab, and the preview runs in a locked-down sandbox. Why that beats a server-side converter, how to inspect the markup yourself, and where converting in the browser stops helping.
