XLSX

XLSX files are Excel files that use the Office Open XML format, introduced with Microsoft Excel 2007.

XLSX files can contain multiple sheets, and each sheet can contain multiple rows and columns of data. They offer several advantages over the older XLS format.

Key features of XLSX files include:

  • Improved compression, resulting in smaller file sizes
  • Enhanced security features, including password protection and digital signatures
  • Better recovery from file corruption
  • Support for more rows (1,048,576) and columns (16,384) per sheet
  • Compatibility with a wide range of applications and programming languages

XLSX files are based on XML and ZIP technologies, making them more accessible for third-party software to read and write.

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.

Originally created for JavaScript, JSON quickly has become the dominant format for web data exchange due to its simplicity and versatility. It's now widely used across various programming languages and platforms.

Primarily used in web applications, JSON efficiently represents structured data from simple key-value pairs to complex nested objects and arrays, making it ideal for client-server communication.

Schema

JSON's flexible structure, while advantageous, can pose challenges for data integrity and processing, especially with large or complex datasets.

Konbert automatically detects the schema of your JSON data. By scanning your JSON file to identify its structure, we ensure all data is accurately captured and maintained throughout the conversion process, preserving the integrity of your information.

Character encoding

As stated by the RFC 8259, we expect strings in uploaded JSON files to be encoded in UTF-8.

If your file contains non UTF-8 characters, you might get an error when parsing your data.

Nested data

We support reading and flattening nested objects and arrays in case you want to convert it to flat data like CSV or Excel.
