Question 1

What Excel formats are supported?

Accepted Answer

We support both modern XLSX files (Excel 2007 and later) and legacy XLS files (Excel 97-2003). Both formats are fully compatible with our converter.

Question 2

Can I convert multiple sheets at once?

Accepted Answer

Yes! Our converter allows you to select which sheets to convert from your Excel workbook. You can convert a single sheet or all sheets at once, with each sheet becoming a separate JSON structure.

Question 3

How are Excel formulas handled?

Accepted Answer

Formulas are converted to their calculated values, not the formula itself. This ensures you get the actual data rather than formula strings in your JSON output.

Question 4

What JSON output formats are available?

Accepted Answer

We offer multiple output formats including: array of objects (most common), object of arrays, and nested structures. Choose the format that best fits your application's needs.

Question 5

Are dates and numbers preserved correctly?

Accepted Answer

Yes! Our converter intelligently detects and preserves data types. Excel dates are converted to ISO 8601 format, numbers remain as numeric types, and text is preserved as strings.

Question 6

Is there a limit on the number of rows?

Accepted Answer

The file size limit is 10MB for anonymous users, which typically allows for tens of thousands of rows depending on the data complexity. For larger files, contact us about enterprise solutions.
