Excel ⇄ JSON: Parse Locally (No Upload)
Typical scenarios: ① the client sends a spreadsheet that the front end needs to use; ② an API needs JSON but the source is a spreadsheet; ③ organize JSON data into a downloadable table.
How to use: upload a spreadsheet file or paste JSON into the input box. The tool parses and converts it locally in your browser — copy or download the result. Files are never uploaded.
Notes: ① multiple sheets are listed by name for you to pick; ② numbers and dates keep their original types and won't all become text; ③ files with charts, images, or merged cells keep only the data after conversion — styling is lost.
