About Excel to JSON

Converting a sheet to JSON turns rows and columns into structured data that a script, an API or an application can read directly — the usual bridge between a spreadsheet someone maintains and a system that consumes it.

How to use it

  1. Upload the XLS or XLSX file.
  2. Convert it to JSON.
  3. Download the JSON output.

Worth knowing

The first row is treated as the field names, so it needs to contain clean, consistent headers. Merged cells and blank header columns are the most common cause of odd output.

Common questions

How are dates handled?
Spreadsheet dates are stored as numbers internally, so check date fields in the output and reformat if needed.
What about multiple sheets?
Convert the sheet holding the data you want; combining several sheets is a job for the receiving system.
