Markdown tables are a popular way to present structured data in documentation, GitHub READMEs, wikis, and technical writing. This tool extracts that tabular data and converts it into JSON — the universal data interchange format used by web APIs, databases, and applications. Simply paste any standard Markdown table and instantly get a clean JSON array you can use in code. For the reverse operation, try our JSON to Markdown converter.
All processing happens in your browser. Your Markdown table data never touches a server, meaning your documentation content stays private. The conversion uses pure JavaScript to parse the pipe-delimited table format and serialize it to JSON.
When working with documentation-heavy projects, it's common to need to re-use table data from README files or wikis in actual code. This tool bridges that gap. You can also pair it with our Markdown to CSV converter or Excel to Markdown tool to move data between all common formats.
A Markdown Table to JSON Converter is a free online tool that transforms Markdown table syntax (pipe-delimited tables) into structured JSON data. The converter reads the column headers from the first row, skips the separator row, and produces an array of JSON objects where each row becomes an object with header-keyed properties. This is useful for extracting structured data from documentation, README files, and wikis for use in applications and APIs.
The tool accepts standard GitHub Flavored Markdown (GFM) table syntax: a header row with pipe-separated columns, a separator row with dashes (e.g. |---|---|), and one or more data rows. Extra spaces around cell content are trimmed. The separator row supports alignment markers (colons) like |:---| or |:---:|, which are ignored for conversion purposes.
Paste your Markdown table into the input area on the left, or click Sample to load an example. The tool converts it instantly to a JSON array displayed on the right. Click Copy to copy the JSON, or Download to save it as a .json file. All processing happens in your browser — no data is sent to any server.
The output is a pretty-printed JSON array of objects. Each object represents one data row, with the column headers as keys and cell values as string values. For example, a table with Name and Age columns produces: [{"Name":"Alice","Age":"30"}, {"Name":"Bob","Age":"25"}]. All values are strings — no type inference is performed.
Absolutely. All conversion happens entirely in your browser using JavaScript. Your Markdown content never leaves your device and is never sent to any server. This ensures complete privacy for sensitive documentation or data.
Yes. The converter parses each cell's content as-is, trimming leading and trailing whitespace. If cell values contain escaped pipe characters (\|), they will appear as-is in the JSON output. The tool handles Unicode characters, numbers, and most special characters without issues.
