XLSX to MD Java Overview
Convert Excel spreadsheets (XLS/XLSX) into clean Markdown tables built for AI applications, LLM ingestion, embeddings, RAG pipelines, and documentation workflows in GitHub, Obsidian, and static site generators. Every worksheet becomes a table under its sheet name heading, with values rendered exactly as the spreadsheet displays them: dates, currencies and percentages keep their number formats, merged cells span every covered row and column, and hyperlinks stay clickable links.
You choose what is converted and how. Select worksheets by name or index or convert only the active sheet, include hidden rows and columns when needed, and switch between displayed values, raw data, and formulas with the CellValues parameter. Password protected workbooks are accepted, and charts are recovered as tables of their data points, so their numbers stay available to readers and language models alike.
The Images parameter decides what happens to the pictures in a workbook. Use embed for one self contained file, extract to get the images as separate files, remove for the most compact text, or describe to let an AI model turn images into text: scanned paragraphs and tables are transcribed, charts and photos get short descriptions, and decorative images are dropped. The last option produces text only Markdown for LLM and RAG pipelines.
Simply upload your Excel workbook and receive a structured Markdown file ready for publishing, analysis, or AI ingestion. Includes a ready-to-use Java library.

File
File Supported formats: .xls .xlsxFile to be converted. Value can be URL or file content.
Password
StringSets the password to open protected documents.
Images
Collection Default: embedControls how images are handled in the resulting Markdown. Embed produces a self-contained document with images embedded as base64 data URIs. Extract saves images as separate files referenced by relative links, the result is a zip archive with the Markdown and image files, or a plain Markdown file when the document has no images. Remove replaces images with their alt text when available, producing compact output suited for machine processing. Describe replaces every image with AI generated text: scanned text and tables are transcribed, pictures become short descriptions, producing text-only Markdown for LLM and RAG scenarios.
SheetHeadings
Bool Default: TrueWrite each worksheet's name as a Markdown heading above its table.
CellValues
Collection Default: formattedWhat a cell contributes to the table. Formatted renders values as the spreadsheet displays them, keeping date, currency and percentage formats. Raw outputs the underlying values without number formatting, dates in ISO 8601. Formulas outputs the formula itself for formula cells and formatted values for plain cells.
FirstRowIsHeader
Bool Default: TrueUse the first row of each sheet as the table header. When disabled, spreadsheet column letters (A, B, C) become the header and the first row stays a data row.
ActiveWorksheetOnly
Bool Default: FalseConvert only the active worksheet. When disabled, all worksheets are converted.
WorksheetIndex
StringSet one or several worksheet indexes(number) separated by comma to convert. If value is not set all worksheet will be converted.
WorksheetName
StringSet one or several worksheet names separated by comma to convert. If value is not set all worksheet will be converted.
IncludeHiddenRows
Bool Default: FalseInclude hidden rows in the output.
IncludeHiddenColumns
Bool Default: FalseInclude hidden columns in the output.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
