About this tool
Listing ops and agency tooling often hand you a spreadsheet, a YAML config, or a CSV export that needs to become JSON for an API, a CMS, or a one-off script. This converter parses ten common formats in the browser and prints structured JSON you can copy or download.
Supported families include CSV/TSV, XML, YAML, Excel (XLSX/XLS), TOML, INI/config, JSON5, properties, and log-like text. Max size is 10 MB. Processing is instant for typical files.
This is a utility for data handoffs, not a photo tool — it sits in Convert for teams that also ship listing media. Pair with Web Page Capture when you need page content, or Files to PDF when the deliverable is a packet instead of JSON.
Always validate sensitive client data before pasting JSON into third-party systems. Free, no account, browser-side parsing.
When converting Excel, confirm which sheet you need; multi-sheet workbooks become nested JSON that may require a single sheet export first.
