upload_max_filesize=50M and post_max_size=64M or higher.Convert rows from an Excel workbook into JSON ready for apps, API testing and data migration.
Convert modern XLSX worksheets, shared strings, numbers, booleans, and cached formula values.
Export a single array or one JSON object with each worksheet grouped by its name.
Choose headers or arrays, preview the result, then copy or download the JSON file.
Each worksheet contains rows and columns. With first-row headers enabled, column headings become JSON keys and subsequent rows become records. Otherwise, rows are exported as arrays. Empty cells become null.
Numbers and booleans retain their value types where possible. Supported Excel date-formatted cells are converted to ISO-like date strings. Formulas are not recalculated: their last stored result is used.

| All sheets | Object keyed by sheet name | Whole-workbook data |
