## Errors

#### "Aw Snap!" or "Oops, an error has occurred!"
|

|

Browsers have strict memory limits and large spreadsheets can exceed the limits.

||||
server with NodeJS or some other server-side technology.
|
||||
|

If the files are small, please [report to our issue tracker](https://git.sheetjs.com/sheetjs/sheetjs/issues)

#### Browser is stuck!
|

|
||||
By default, operations run in the main renderer context and block the browser
|
||||
from updating. [Web Workers](../demos/worker) offload the hard work to separate
|
||||
contexts, freeing up the renderer to update.
