Technical and Performance Limits

This page describes known technical and practical limits. These limits only impact users with very large/complex documents.

Key Findings:
  • Currently, the Word add-in can only update 49 tables in a document. Cloud reporting does not have this limit.
  • Word performance becomes very slow when the document contains over 2500 content controls (this issue is not related to the add-in).

* Medium tables tested with 10x5 (50 cell tables). Large tables tested with 10-column by 30-row tables (300 cells). With 49 tables, which is 14,700 cells.

^ update performance is significantly faster if the user's cursor is at the top of the document and no/few large tables are visible. Slow update speeds are related to display updating, not replacing content.
