# Welcome to the HTML Converter Knowledge Base!

Here you’ll find everything you need to master converting HTML and MHTML documents into a wide variety of formats.

Our conversion engine follows a simple yet powerful rule: **at least one side of the conversion – either the source or the target – must be HTML or MHTML**. The counterpart can be any of the supported formats, such as **XLSX, XLSB, XLSM, XLT, CSV, TSV, JSON, XML, EPUB, AZW3**, and many more.

This means you can:

- Turn an HTML page into an Excel workbook (XLSX, XLSB, XLM, etc.).
- Export an MHTML email archive to a CSV or TSV file.
- Transform a spreadsheet into a clean HTML or MHTML report.
- Convert HTML to JSON for API consumption, and vice‑versa.

Each format is listed in the **supported‑type table**, so you can quickly verify that your desired input‑output pair complies with the rule.

## Getting started

1. **Select your source type** – choose **HTML** or **MHTML**.  
2. **Pick the target format** from the drop‑down menu.  

The knowledge base provides step‑by‑step guides, sample code snippets, and troubleshooting tips for every combination.

Explore the sections below to find detailed tutorials, API references, and best‑practice recommendations that will help you get the most out of the HTML Converter.
