What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is commonly used to transmit data between a server and web application as an alternative to XML. JSON is primarily used when working with APIs, web services, and configurations.

Data Type Mismatch

When converting Excel data to JSON, the data types in Excel (e.g., dates, currency, text) may not map directly to JSON formats, leading to incorrect interpretations or loss of data fidelity.

Nested Structures

Excel does not support nested structures natively, which may result in loss of hierarchical data when converting to JSON if relationships between rows and columns are not preserved.

Empty Cells

Empty cells in Excel can lead to missing keys or unexpected null values in the resulting JSON, complicating data handling and interpretation.

Special Characters Handling

Special characters within Excel cells may not be correctly escaped during conversion, potentially causing errors or incorrect formatting in the JSON output.

What are the differences between XLSX and XLS?

File Format

XLSX is the modern file format used by Microsoft Excel, introduced with Excel 2007, and is based on the Open XML standard. In contrast, XLS is the older binary file format used by earlier versions of Excel up to 2003.

File Size

XLSX files are generally smaller in size compared to XLS files because they use Zipping compression, making it more efficient for storage and sharing.

Data Capacity

XLSX supports a significantly larger amount of data, allowing for up to 1,048,576 rows and 16,384 columns per worksheet, while XLS is limited to 65,536 rows and 256 columns.

Features and Functions

XLSX files support newer features and functions available in Excel 2007 and later versions, such as improved charting tools, Sparklines, and enhanced formulas. XLS files do not have access to these advanced features.
