How to Convert LaTeX to JSON

01

Paste your LaTeX table code or upload a .tex file.

02

Choose 'Array' for a simple list of lists, or 'Object' to use the first row as keys.

03

Click 'Convert' to generate the JSON output.

Key Features

Smart Parsing

Automatically handles standard LaTeX tabular environments and ignores formatting commands.

Multiple Formats

Convert to a simple 2D array or structured JSON objects using headers.

Clean Output

Strips common LaTeX styling like \textbf and \textit for clean data extraction.

FAQ

Does it support nested tables?

Currently, it parses the first tabular environment found. Nested tables may need to be extracted manually.

Can I convert whole LaTeX documents?

This tool is optimized for tables. It will look for the tabular environment within your document.

Paste a LaTeX tabular environment and this tool instantly converts it into structured JSON—producing either a 2D array of rows and columns or an array of objects that uses the first row as keys. It strips formatting commands like \textbf and \textit, and runs entirely in your browser with no file upload.

How to Use the LaTeX to JSON Converter

  1. 1

    Paste your LaTeX table

    Enter the LaTeX code containing a tabular environment, or upload a .tex file. The parser locates the first tabular block in your input.

  2. 2

    Choose a conversion mode

    Select "2D Array" for a simple list of rows and columns, or "Array of Objects" to treat the first row as keys for each record.

  3. 3

    Convert to JSON

    Click Convert to parse the cells, strip styling commands such as \textbf and \textit, and serialize the table into clean JSON.

  4. 4

    Copy the output

    Review the structured JSON in the output panel and copy it for use in your code, API, or data pipeline.

Frequently Asked Questions

Does it support nested tables?
Currently, it parses the first tabular environment found. Nested tables may need to be extracted manually.
Can I convert whole LaTeX documents?
This tool is optimized for tables. It will look for the tabular environment within your document and convert that.
What is the difference between 2D Array and Array of Objects mode?
2D Array mode outputs each row as a list of cell values. Array of Objects mode uses the first row as keys and maps each following row to a JSON object, which needs at least one header row plus one data row.
Are LaTeX formatting commands removed from the output?
Yes. Common styling commands such as \textbf and \textit are stripped so the JSON contains clean cell values without markup.
Is my LaTeX data uploaded to a server?
No. All parsing runs entirely in your browser, so your LaTeX source never leaves your device.
