AI Data Cleaning Template for Google Sheets

AI Data Cleaning Template for Google Sheets

Dirty data costs businesses time and money. Inconsistent formatting, duplicate entries, missing fields, misspelled names, and mixed-up columns turn what should be a simple analysis into hours of manual cleanup. Every data professional has spent entire afternoons fixing spreadsheets before they could do any real work with them.

This AI Data Cleaning Template for Google Sheets uses SheetAI to automate the most painful parts of data cleanup. The AI standardizes formats, extracts structured fields from messy text, classifies entries into consistent categories, and flags duplicates and anomalies. Instead of writing complex formulas or cleaning row by row, you let AI handle the grunt work.

Whether you are preparing data for a mail merge, cleaning up a CRM export, standardizing survey responses, or normalizing product catalogs, this template gives you a repeatable system for turning messy data into clean, usable information.

Features

Format Standardization

Inconsistent formatting is the most common data quality issue. Phone numbers in five different formats. Addresses with abbreviations in some rows and full words in others. Names in mixed case. SheetAI standardizes all of it.

=SHEETAI("Standardize this phone number to (XXX) XXX-XXXX format: "&B2)

=SHEETAI("Standardize this address to proper USPS format with full state name: "&C2)

=SHEETAI("Fix the capitalization of this person's name: "&A2)

Run these across thousands of rows and your data becomes consistent in seconds.

Structured Data Extraction

Real-world data often arrives as unstructured text. A single column might contain full addresses, or a notes field might have phone numbers, emails, and company names all mashed together. SHEETAI_EXTRACT pulls out exactly what you need.

=SHEETAI_EXTRACT(B2, "city, state, zip code")

=SHEETAI_EXTRACT(D2, "email address")

=SHEETAI_EXTRACT(E2, "company name, job title")

Each extracted field goes into its own clean column, ready for analysis or import into another system.

Category Standardization

When data comes from multiple sources or free-text input, the same thing gets described in dozens of different ways. "United States", "US", "USA", "U.S.A.", "america" should all be one value. SHEETAI_CLASSIFY normalizes these entries.

=SHEETAI_CLASSIFY(F2, "United States, Canada, United Kingdom, Australia, Germany, France, India, Other")

This works for countries, industries, job titles, product categories, or any field where free-text entries need to map to a controlled list.

Anomaly Detection

SheetAI can scan your data for values that look wrong or out of place.

=SHEETAI("Is this value an anomaly in this dataset? Value: "&B2&". Typical values in this column: "&TEXTJOIN(", ",TRUE,B$2:B$20)&". Answer Yes or No with brief reason.")

This catches data entry errors like a zip code in a phone number field, a price that is 100x higher than the rest, or a date from 1920 in a column of recent entries.

Deduplication Assistance

Finding duplicates is straightforward when values match exactly. The hard part is fuzzy matching, where "John Smith" and "Jon Smith" are probably the same person. SheetAI helps identify likely duplicates.

=SHEETAI("Are these two records likely the same person? Record 1: "&A2&", "&B2&", "&C2&". Record 2: "&A3&", "&B3&", "&C3&". Answer: Yes, No, or Maybe.")

Flag the probable matches, then manually confirm before merging records.
