If you have a large amount of data (greater than 100 MB or 1000,000 rows) to be uploaded into Zoho Analytics, loading them using the Web Graphical Interface of Zoho Analytics, might not be the best way. As the upload happens over the Internet, slow or unreliable network connection might cause failures or interrupt the large data upload. In these cases, we recommend the following mechanism:

• CSV Zoho Databridge - This tool does a smart upload by splitting the data into smaller manageable segments and uploads them in sequence into Zoho Analytics. This tool currently supports upload data in CSV, TSV or any tabular text file formats.
  

 You could also Zip the file and upload from the Web User Interface, as long as the Zipped file content size is less 100MB and containing not more than 1000,000 rows. CSV Zoho Databridge does not have this restriction. But the overall limitation of having a maximum 1000,000 rows in a table still applies, when you are in the Free or Trial Editions of Zoho Analytics.
