Data

Spreadsheet and data tools

Convert CSV, TSV, JSON, XML, YAML and Excel data for spreadsheets, reports and imports, in your browser.

Before you start

Rows and columns convert without surprises; nesting is where data changes shape. JSON and XML can hold lists inside lists, while a spreadsheet is flat, so nested values end up as text in a single cell or spread across extra columns. Open the result and check the headers and a few rows before you import it anywhere.
