Format Details
XLS
XLS is the legacy binary spreadsheet format used by Microsoft Excel from 1987 through the Office 2003 era, based on Microsoft's proprietary Binary Interchange File Format (BIFF). It stores worksheets, formulas, charts, and macros in a binary structure that requires Microsoft's format specification to parse correctly. XLS remains common in older enterprise systems and when compatibility with legacy versions of Excel is required.
dataMarkdown
Markdown is a lightweight plain-text markup language created by John Gruber in 2004 to make writing formatted content for the web as easy as possible. It uses minimal punctuation-based syntax to define headings, emphasis, links, images, lists, and code blocks that convert cleanly to HTML. Markdown is the dominant format for README files, software documentation, technical blogs, and static site generators across the entire software industry.
documentConverting XLS to MD: what actually changes
XLS to Markdown is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .XLS and .MD each hold
.XLS is a data format built for analysing, importing or exchanging records, storing rows, columns and value types. .MD is a document format built for reading, printing or circulating a document, storing text, layout, fonts and images. Converting between them is a decision about which of those two jobs the result needs to do.
What changes when categories differ
The records are laid out into a readable document for reading, printing or circulating a document. Structure becomes presentation — columns become a table or list, and what was a machine-readable field is now something a person reads.
When this conversion is the right one
Reach for .MD when you need a file for reading, printing or circulating a document, starting from analysing, importing or exchanging records. If that is not what you are after, check what else .XLS converts to before committing to this target.
Tips for a clean XLS to MD conversion
Start from the original file
Convert the .XLS you started with, not an earlier .MD output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Application/vnd.ms-excel becomes text/markdown. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Confirm the structure first
Open the .XLS briefly and check delimiters, headers and encoding. A misplaced separator or a stray quote is the usual reason the output looks wrong even though the conversion succeeded.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge data files, split or compress the source first.
