Zoho Analytics has the following restrictions on the size of data import. You can upload a maximum of 1,000,000 rows and the file size should not exceed 100 MB.
However, you can upload huge CSV files using the Databridge. Zoho Databridge is a lightweight independent utility that bridges your on-premise data source and Zoho Analytics server to enable easy data import. You can also automate the import process to synchronize the data from your local /hosted database into Zoho Analytics at a periodic interval.
