TEX vs CSV Format Comparison
| Aspect | TEX (Source Format) | CSV (Target Format) |
|---|---|---|
| Format Overview |
TEX / LaTeX
Document Preparation System
LaTeX is a high-quality typesetting system designed for scientific and technical documentation. Created by Leslie Lamport as a macro package for Donald Knuth's TeX system, it's the standard for academic publishing, especially in mathematics, physics, and computer science. Scientific Academic |
CSV
Comma-Separated Values
CSV is a simple, universal format for storing tabular data. Each line represents a row, with values separated by commas. It's the most widely supported format for data exchange between spreadsheets, databases, and analysis tools. Tabular Data Universal |

Why Convert LaTeX to CSV?
Converting LaTeX documents to CSV format is essential for extracting tabular data from academic papers, research reports, and scientific publications. CSV provides a universal format that can be imported into any spreadsheet application or data analysis tool.
Scientific papers often contain valuable experimental results, statistical data, and comparison tables buried in LaTeX tabular environments. Converting to CSV makes this data accessible for further analysis, visualization, or integration into meta-analyses.
CSV's simplicity means the extracted data can be immediately used in Python pandas, R dataframes, Excel, or database systems. This is particularly valuable for researchers who need to aggregate results from multiple papers or perform computational analysis on published data.
Key Benefits of Converting TEX to CSV:
- Data Extraction: Pull tables out of academic papers
- Spreadsheet Compatible: Opens in Excel, Google Sheets, LibreOffice
- Data Analysis: Import into pandas, R, MATLAB
- Database Import: Load into SQL databases
- Meta-Analysis: Aggregate data from multiple papers
- Visualization: Create charts from extracted data
- Machine Learning: Use as training/test datasets
Practical Examples
Example 1: Experiment Results Table
Input TEX file (results.tex):
\begin{table}[h]
\caption{Classification Performance}
\begin{tabular}{|l|c|c|c|}
\hline
Model & Precision & Recall & F1 Score \\
\hline
Logistic Regression & 0.82 & 0.79 & 0.80 \\
Random Forest & 0.88 & 0.85 & 0.86 \\
XGBoost & 0.91 & 0.89 & 0.90 \\
Neural Network & 0.93 & 0.91 & 0.92 \\
\hline
\end{tabular}
\end{table}
Output CSV file (results.csv):
Model,Precision,Recall,F1 Score Logistic Regression,0.82,0.79,0.80 Random Forest,0.88,0.85,0.86 XGBoost,0.91,0.89,0.90 Neural Network,0.93,0.91,0.92
Example 2: Survey Data
Input TEX file (survey.tex):
\begin{tabular}{lrrr}
\toprule
Age Group & Respondents & Satisfied & Percentage \\
\midrule
18-24 & 150 & 120 & 80\% \\
25-34 & 280 & 238 & 85\% \\
35-44 & 195 & 156 & 80\% \\
45+ & 125 & 94 & 75\% \\
\bottomrule
\end{tabular}
Output CSV file (survey.csv):
Age Group,Respondents,Satisfied,Percentage 18-24,150,120,80% 25-34,280,238,85% 35-44,195,156,80% 45+,125,94,75%
Example 3: Multi-Column Scientific Data
Input TEX file (measurements.tex):
\begin{tabular}{ccccc}
Sample & Temp (C) & Pressure (kPa) & Volume (L) & Mass (g) \\
A1 & 25.3 & 101.2 & 1.05 & 2.34 \\
A2 & 25.1 & 101.4 & 1.03 & 2.31 \\
B1 & 30.2 & 102.1 & 1.12 & 2.45 \\
B2 & 30.0 & 102.0 & 1.10 & 2.42 \\
\end{tabular}
Output CSV file (measurements.csv):
Sample,Temp (C),Pressure (kPa),Volume (L),Mass (g) A1,25.3,101.2,1.05,2.34 A2,25.1,101.4,1.03,2.31 B1,30.2,102.1,1.12,2.45 B2,30.0,102.0,1.10,2.42
Frequently Asked Questions (FAQ)
Q: What LaTeX table types are supported?
A: The converter supports standard LaTeX table environments including tabular, table, longtable, and booktabs-styled tables. Complex merged cells (multirow/multicolumn) are flattened appropriately for CSV format.
Q: How are multiple tables handled?
A: If your LaTeX document contains multiple tables, each table can be extracted to a separate CSV file, or combined into one file with table separators. The extraction preserves the order of tables as they appear in the document.
Q: What happens to mathematical notation in cells?
A: Mathematical notation in table cells is converted to plain text representation. Simple expressions like superscripts and subscripts are preserved where possible (e.g., $x^2$ becomes x^2). Complex equations may need manual cleanup.
Q: Can I import the CSV into Excel?
A: Absolutely! CSV is Excel's native import format. Simply open the CSV file with Excel, or use Data > From Text/CSV for more control over parsing. Google Sheets and LibreOffice Calc also open CSV files directly.
Q: How are special characters handled?
A: LaTeX special characters and commands are converted to their text equivalents. Commas within data are properly quoted or escaped according to RFC 4180 standards to ensure correct parsing by spreadsheet applications.
Q: Is the data quality preserved?
A: Yes, numerical data, text, and percentages are preserved exactly as they appear in the LaTeX source. The converter maintains the precision of decimal numbers and handles various number formats correctly.
