Excel to MediaWiki Converter

Excel to MediaWiki Table Converter

Use this free Excel to MediaWiki converter to turn spreadsheet tables into clean MediaWiki wikitable markup. It is ideal for quickly publishing data from Excel to MediaWiki, Wikipedia, company wikis, and technical documentation without hand‑coding table syntax.

Key Features & Benefits

• Instant Excel to MediaWiki conversion: Upload any .xlsx or .xls file and the tool converts the first sheet into a proper {| class="wikitable"} table.
• Header row support: Treat the first row as column headers or auto‑generate header labels such as Column 1, Column 2, etc.
• Standards‑compliant MediaWiki syntax: The converter uses ! for headers, |- for rows, and || for cells, matching common wiki engines.
• Huge time‑saver: Avoid manually re‑typing tables when copying content from Excel into your wiki.
• Browser‑only processing: Your spreadsheet never leaves your device, making the tool safe for internal and private data.

How to Convert Excel to MediaWiki

1. Prepare your Excel sheet: Place the table you want to publish on the first worksheet. Use one row per record and one column per field.
2. Upload your Excel file: Click the upload area or drag and drop your .xlsx or .xls file into the converter.
3. Set header handling: If the first row contains labels such as Name, Value, or Date, leave “First row is header” checked. Otherwise, uncheck it to treat every row as data.
4. Review the MediaWiki output: The right‑hand panel shows fully formatted wikitable markup ready to paste into your wiki page.
5. Copy or download: Use the Copy button to copy the markup to the clipboard, or Download to save it as a text file.

Example: Excel to MediaWiki Table

Imagine your Excel sheet contains:

• Row 1: Product | Price | Stock
• Row 2: Widget A | 9.99 | 42
• Row 3: Widget B | 14.50 | 10

The converter will generate MediaWiki code similar to:

{| class="wikitable"
! Product !! Price !! Stock
|-
| Widget A || 9.99 || 42
|-
| Widget B || 14.50 || 10
|}
	

You can paste this directly into a MediaWiki or Wikipedia page and see a nicely formatted table automatically.

Common Use Cases

• Publishing reports to wikis: Move monthly KPI tables, project dashboards, or product catalogs from Excel to your company wiki.
• Technical and documentation teams: Share configuration matrices, feature comparison tables, or test results in MediaWiki pages.
• Open‑source and knowledge bases: Prepare content for Wikipedia‑style sites using familiar Excel workflows.
• Internal knowledge sharing: Standardize how teams publish structured information without requiring them to learn MediaWiki syntax.

Privacy & Security

All Excel to MediaWiki conversion happens locally in your browser. The Excel file is processed in JavaScript and is never uploaded to our servers. This makes the tool safe for confidential business data, internal KPIs, or private documentation.

Frequently Asked Questions (FAQ)

Which Excel formats are supported?

The converter accepts both .xlsx and .xls files. If the file type or extension does not match a standard Excel workbook, you will see a clear error message.

Does the tool support multiple sheets?

Currently the converter uses the first worksheet in your Excel file. If you have multiple tables, place the one you want to convert on the first sheet or save it as a separate file.

What happens if I don't have a header row?

If “First row is header” is unchecked, the tool treats every row as data and will still generate a valid MediaWiki table. You can manually edit the header line later if needed.

Can I use the output on Wikipedia?

Yes. The generated wikitable syntax is compatible with MediaWiki‑based sites, including Wikipedia, as long as your content follows their contribution guidelines.

Is any of my Excel or wiki content stored on your servers?

No. The conversion is fully client‑side. Your spreadsheet is processed only in your browser, and you decide where to paste or save the resulting MediaWiki markup.
