About this tool
Are you familiar with the situation when you copied a table from Excel or Google Sheets and you urgently need to turn it into a beautiful Markdown table for GitHub or structured JSON for a developer, but you are too lazy to do it manually?
Our office spreadsheet converter solves this task in one click, completely confidential. Because data processing is done locally in your browser, your financial reports or customer bases are never leaked online.
The tool allows you to instantly convert data in any direction between CSV, TSV, HTML tables, Markdown tables and JSON arrays with the ability to fine-tune delimiters.
Example. CSV text a,b on the first line and 1,2 on the second becomes a JSON array with one object whose a is 1 and whose b is 2.
Limit. JSON input must be an array, and Markdown conversion expects a pipe table rather than a free-form document.
