Question 1

What JSON formats are supported?

Accepted Answer

Our converter supports all valid JSON formats including objects, arrays, nested structures, and mixed data types. Whether you have a simple JSON object or a complex nested array, FileMint can convert it to Excel.

Question 2

Is there a file size limit?

Accepted Answer

Yes, for anonymous users, the file size limit is 10MB. This is sufficient for most JSON files. If you need to convert larger files, please contact us for enterprise solutions.

Question 3

What's the difference between XLSX and XLS?

Accepted Answer

XLSX is the modern Excel format (Excel 2007 and later) that supports larger files and more features. XLS is the legacy format (Excel 97-2003) with more limited capabilities. We recommend using XLSX unless you need compatibility with older Excel versions.

Question 4

How are nested JSON objects handled?

Accepted Answer

Nested objects are flattened into columns with dot notation (e.g., 'user.name', 'user.email'). Arrays are converted into multiple rows or serialized as strings depending on their structure, ensuring all your data is preserved.

Question 5

Is my data secure?

Accepted Answer

Absolutely! Your files are processed securely on our servers and are automatically deleted immediately after conversion. We never store or share your data with third parties.
