Local Data

There is no standard cross-platform approach to read and write files and data. XLSX.readFile and XLSX.writeFile rely on platform-specific APIs to perform the file read and write operations. Not all platforms support the APIs used in the library.

Demos in this section cover local APIs that are not embedded in the library:

• Local File Access - Reading and writing files using various platform APIs
• Local Storage API - Reading and writing data in an in-browser Key-Value store
• Clipboard Data - Reading and writing data and files in the clipboard
• IndexedDB API - Reading and writing data in an in-browser NoSQL database
