3 Enterprise Necessities The place Information Prep with Excel is Much less Than Stellar


Excel has lengthy been the software for enterprise analysts to carry out light-weight knowledge preparation duties – figuring out outliers and errors, aggregating values, and mixing knowledge into one spreadsheet for analytics.  Nevertheless, all too typically, enterprise customers waste time utilizing Excel to manually profile and course of knowledge.

Fact is that Excel is insufficient for enterprise tasks that comprise large-scale knowledge units, contain group collaboration, and require knowledge accuracy in a brief period of time.

Amongst many, there are 3 areas the place Excel’s limitations are – to properly put it – limiting and too time consuming for knowledge preparation at scale:

1) Interactive with Information Past 1 Million Rows: With Excel, knowledge is proscribed to 1,000,000 rows. Even with lower than that quantity, the bigger the variety of rows, the slower Excel will get and the better the possibility of Excel crashing – and taking the entire person’s modifications down with it.

2) Information Profiling: To profile knowledge in Excel, customers sometimes create filters and pivot tables – however issues come up when a column comprises 1000’s of distinct values or when there are duplicates ensuing from completely different spellings. And since Excel filters haven’t any visible illustration for every worth, the person should swap backwards and forwards between pivot tables and filtered knowledge to get a (partial) understanding of the information.

3) Information Governance and Belief: With Excel, there is no such thing as a precise audit path or knowledge lineage. You’ll be able to’t see the steps taken to cleanse a selected dataset, except for spending your time making sense out of advanced macros. And even with that, it’s essential to save each model of Excel and apply feedback to mark vital modifications.

These necessities and extra display the place knowledge preparation with Excel completely lacks ‘enterprise’ readiness.
