# File Upload Processing Modes and Limits

Upload processing modes in Tableau Next are based on file size and column count thresholds. Files exceeding standard limits are automatically queued for asynchronous processing, optimizing resource allocation without impacting platform stability.

### Required Editions

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small edition"><colgroup><col></colgroup><tbody><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;"><a href="https://help.salesforce.com/s/articleView?id=analytics.tua_editions.htm&amp;language=en_US" target="_blank">View supported editions.</a></td></tr></tbody></table>

The table outlines the processing mode for different file types and sizes:

  
| File Type | File Size & Column Count | Processing Mode |
| --- | --- | --- |
| Excel (.xlsx) | Less than 10 MB AND less than 95 columns | Standard |
| Excel (.xlsx) | 10 MB up to 100 MB OR 95–500 columns | Asynchronous (Beta) |
| CSV | Less than 100 MB AND less than 95 columns | Standard |
| CSV | 100 MB up to 2 GB OR less than 1050 columns | Asynchronous (Beta) |

Note Asynchronous processing is a pilot or beta service that is subject to the Beta Services Terms at Agreements - Salesforce.com or a written Unified Pilot Agreement if executed by Customer, and applicable terms in the Product Terms Directory. Use of this pilot or beta service is at the Customer's sole discretion.

Column Count Thresholds

Each data type limit is 800 columns. While a dataset can contain more than 800 total columns across different types, it can’t exceed 800 columns of any single type. For example, a file with 800 text fields and 250 number fields is acceptable. A file with 801 text fields and 10 number fields returns an error.
