Convert MediaWiki to TSV

Why Convert MediaWiki to TSV?

Converting MediaWiki markup to TSV format is essential when you need to extract tabular data from wiki pages for analysis, import into spreadsheets, or load into databases. Wikipedia and MediaWiki-based wikis contain vast amounts of structured data in wiki tables, and converting these to TSV makes the data accessible to standard data processing tools like Excel, Google Sheets, Python pandas, and SQL databases.

MediaWiki tables use a complex markup syntax with {| for table start, |- for row separators, ! for header cells, and || for cell separators. While this syntax renders beautifully in a web browser, it is not suitable for data analysis or programmatic processing. TSV format strips away all wiki markup and presents the raw data in a clean, tab-delimited format that any spreadsheet application or data tool can immediately import and process.

TSV is often preferred over CSV for wiki data extraction because wiki content frequently contains commas within cell values (descriptions, lists, addresses), which would require complex quoting in CSV. Tab characters, on the other hand, rarely appear in natural text, making TSV a cleaner choice for data that originates from human-written wiki content. The resulting files import cleanly into Excel, Google Sheets, and database tools without column misalignment issues.

This conversion is particularly valuable for researchers, data analysts, and content managers who need to work with data published on Wikipedia or internal wikis. Rather than manually copying table data cell by cell, converting the entire MediaWiki source to TSV automates the extraction process and preserves all rows and columns accurately, including header information.

Key Benefits of Converting MediaWiki to TSV:

• Data Extraction: Pull tabular data from wiki pages into analysis-ready format
• Spreadsheet Import: Open directly in Excel, Google Sheets, and LibreOffice Calc
• Database Loading: Import wiki data into SQL databases with bulk load operations
• No Quoting Issues: TSV avoids the comma conflicts common in wiki text
• Data Analysis: Process wiki data with Python, R, or other analytical tools
• Clean Output: Strips all wiki formatting to reveal pure tabular data
• Batch Processing: Convert multiple wiki pages with tables in one operation

Practical Examples

Example 1: Wikipedia Data Table Extraction

Input MediaWiki file (countries.mediawiki):

== Countries by Population ==

{| class="wikitable sortable"
|-
! Country !! Population !! Capital !! Continent
|-
| [[China]] || 1,412,000,000 || Beijing || Asia
|-
| [[India]] || 1,408,000,000 || New Delhi || Asia
|-
| [[United States]] || 334,000,000 || Washington, D.C. || North America
|-
| [[Brazil]] || 216,000,000 || Brasilia || South America
|}

Output TSV file (countries.tsv):

Country	Population	Capital	Continent
China	1,412,000,000	Beijing	Asia
India	1,408,000,000	New Delhi	Asia
United States	334,000,000	Washington, D.C.	North America
Brazil	216,000,000	Brasilia	South America

Example 2: Software Comparison Table

Input MediaWiki file (comparison.mediawiki):

== Database Comparison ==

{| class="wikitable"
|-
! Database !! Type !! License !! Latest Version
|-
| '''PostgreSQL''' || Relational || Open Source || 16.2
|-
| '''MySQL''' || Relational || GPL/Commercial || 8.3
|-
| '''MongoDB''' || Document || SSPL || 7.0
|-
| '''Redis''' || Key-Value || BSD || 7.2
|}

Output TSV file (comparison.tsv):

Database	Type	License	Latest Version
PostgreSQL	Relational	Open Source	16.2
MySQL	Relational	GPL/Commercial	8.3
MongoDB	Document	SSPL	7.0
Redis	Key-Value	BSD	7.2

Example 3: Project Status Tracking

Input MediaWiki file (status.mediawiki):

== Sprint Tasks ==

{| class="wikitable"
|-
! Task !! Assignee !! Priority !! Status
|-
| Implement login API || Alice || High || Complete
|-
| Design dashboard || Bob || Medium || In Progress
|-
| Write unit tests || Carol || High || Pending
|}

{{Note|Sprint ends on Friday.}}

Output TSV file (status.tsv):

Task	Assignee	Priority	Status
Implement login API	Alice	High	Complete
Design dashboard	Bob	Medium	In Progress
Write unit tests	Carol	High	Pending

Frequently Asked Questions (FAQ)

Q: What is TSV format?

A: TSV (Tab-Separated Values) is a simple text format for storing tabular data. Each row is a line of text, and columns within a row are separated by tab characters. It is similar to CSV but uses tabs instead of commas as delimiters, which makes it simpler to handle data that contains commas. TSV files can be opened in any spreadsheet application or text editor.

Q: How are MediaWiki tables extracted into TSV?

A: The converter parses MediaWiki table syntax ({| ... |}), identifies header rows (! cells) and data rows (| cells), strips all wiki markup formatting, and outputs each cell value separated by tab characters. Multiple tables in a single wiki page can be extracted into separate sections or files.

Q: Why use TSV instead of CSV for wiki data?

A: Wiki content frequently contains commas in cell values (city names like "Washington, D.C.", lists, descriptions). Using TSV avoids the need for complex quoting rules that CSV requires for comma-containing data. Since tab characters rarely appear in natural wiki text, TSV provides cleaner, more reliable data extraction from wiki tables.

Q: Can I open TSV files in Excel?

A: Yes! Microsoft Excel, Google Sheets, LibreOffice Calc, and most other spreadsheet applications can open TSV files directly. In Excel, you can use File > Open and select the TSV file, or use the Text Import Wizard to specify tab as the delimiter. The data will be automatically arranged into columns.

Q: What happens to non-table content in the MediaWiki file?

A: The converter focuses on extracting tabular data. Non-table content such as headings, paragraphs, lists, and plain text is converted into a structured text representation with appropriate tab separation. Section headings may be preserved as context markers, and list items can be represented as individual rows.

Q: Is wiki formatting stripped from cell values?

A: Yes, all MediaWiki markup is removed from cell values during conversion. Bold markers (''' '''), italic markers ('' ''), link syntax ([[...]]), and other wiki formatting are stripped, leaving only the plain text content. This ensures clean data that can be processed by spreadsheet formulas and database queries.

Q: Can I import TSV data into a database?

A: Absolutely! TSV is one of the standard formats for bulk data import in most database systems. PostgreSQL (COPY command), MySQL (LOAD DATA INFILE), SQLite, and other databases support direct TSV import. This makes it easy to load wiki table data into a database for querying and analysis.

Q: Can I convert multiple MediaWiki files to TSV at once?

A: Yes! Our converter supports batch processing. Upload multiple MediaWiki files simultaneously and each will be converted to its own TSV file. This is ideal for extracting tabular data from multiple Wikipedia articles or internal wiki pages in a single operation.
