Markdown Table to JSON Converter

Paste a pipe-delimited Markdown table into the input box. The tool reads the first row as your column headers, skips the separator line (the row with dashes), and turns every data row into a JSON object. You get back a JSON array where each object's keys match your headers. It all runs in JavaScript right in your browser — nothing gets uploaded anywhere.

Any standard GitHub Flavored Markdown (GFM) table works. That means a header row with pipes, a separator row with dashes like |---|---|, and your data rows below. Alignment markers (colons in the separator, like |:---:| for centered) are fine — the converter just ignores them since JSON doesn't have alignment. Extra whitespace around cell values gets trimmed automatically.

You get a pretty-printed JSON array. Each table row becomes one object, with column headers as keys. So a two-column table with Name and Age gives you something like: [{"Name":"Alice","Age":"30"}, {"Name":"Bob","Age":"25"}]. Every value stays as a string — the tool doesn't try to guess if something is a number or boolean.

I kept everything as strings on purpose. If you have a column with values like "007" or "01onal," auto-converting to numbers would lose those leading zeros. Same with phone numbers, zip codes, and IDs. It's safer to give you strings and let you cast types in your own code where you know the data.

No. The conversion runs entirely in your browser using client-side JavaScript. Your Markdown text never leaves your machine. You can even disconnect from the internet after the page loads and it'll still work.

The converter handles Unicode, emoji, and most special characters without problems. If a cell contains an escaped pipe (\|), it shows up as-is in the output. The main thing to watch for is that the pipe character is what separates columns, so if your data has literal pipes, they need to be escaped in the Markdown.

Right now it handles one table per conversion. If your Markdown file has three tables, paste each one separately. I built it this way because mixing tables with different columns into a single JSON array would create messy data — you'd end up with null fields everywhere.

Copy the output and drop it into your code. In JavaScript it's JSON.parse(), Python has json.loads(), and every other language has a JSON library. I use it a lot for seeding test databases and creating mock API responses. If you ever need to go the other direction, there's a JSON to Markdown converter for that.

Yes, as long as the table is in standard pipe-delimited Markdown. Obsidian, Notion, Typora, Bear — they all export tables in this format. Just copy the raw Markdown table (not the rendered view) and paste it in.

Nope, it's free and there's no account needed. You might also find these useful: JSON to Markdown, JSON to Excel, CSV to Markdown, and Markdown to Excel.
