Frequently Asked Questions
What JSON structure is produced from the spreadsheet?
Each row becomes a JSON object with column headers as keys. All rows are wrapped in a JSON array.
What happens to merged cells?
Merged cells are unmerged during conversion. The value appears in the first cell; other cells in the merge are empty.
Can I use the XLSX-to-JSON output with a REST API?
Yes. The output is standard JSON compatible with any API or JavaScript application.
Can I convert an XLSX file with multiple sheets to JSON?
The tool exports the first sheet. To export other sheets, open the file in Excel and make the desired sheet active before converting.
Can I use the XLSX-to-JSON output in a Python script?
Yes. Save the JSON file and use json.load() to read it in Python.
Does the XLSX-to-JSON output preserve number types?
Yes. Numeric cells are stored as JSON numbers. Text cells are stored as JSON strings.
Can I convert an XLSX database export to JSON?
Yes. The tool extracts all cell values into a JSON array of objects, with column headers as keys.
