Working with Excel data that needs to go into a web app or API? Export your spreadsheet as CSV, paste it here, and get structured JSON in one click. The tool auto-detects delimiters, handles quoted fields with commas and special characters, and outputs either Array of Objects (with headers as keys) or Array of Arrays.

Frequently Asked Questions

How do I export CSV from Excel?
In Excel, go to File > Save As (or Export), then choose "CSV (Comma delimited) (*.csv)" as the format. This creates a plain-text file with your data separated by commas. Then paste the CSV content into the tool or upload the .csv file directly.
Does it handle Excel cells with commas or line breaks?
Yes. When Excel exports CSV, it wraps fields containing commas, quotes, or line breaks in double quotes (RFC 4180 standard). The parser correctly handles these quoted fields — commas inside quotes are treated as part of the field, not as delimiters.
What about special characters and Unicode?
The tool handles UTF-8 encoded CSV, which covers all Unicode characters including accented letters, CJK characters, and emoji. If your Excel file uses a different encoding, save it as "CSV UTF-8 (Comma delimited)" in Excel to ensure compatibility.
Can I convert Excel XLSX files directly?
This tool works with CSV text, not binary XLSX files. First export your Excel file as CSV (File > Save As > CSV), then use the tool to convert the CSV to JSON. This two-step process gives you full control over which sheet and range to export.
Is my spreadsheet data sent to any server?
No. Parsing and conversion run in your browser using JavaScript. Spreadsheet data is not uploaded to our servers during conversion.
