How to Compare Two Columns in Google Sheets

Comparing two columns in Google Sheets is a common task for data analysis and verification. This process can help identify matches, discrepancies, and specific data points across different datasets.

In this guide, we will cover the most effective methods for comparing columns in Google Sheets. Additionally, we'll explore why Sourcetable is a better alternative to using Google Sheets.

How to Compare Two Columns in Google Sheets

Using Formulas to Compare Columns

To compare two columns in Google Sheets, you can use formulas such as =A2=C2 to check if the cells in the two columns are identical. Drag this formula down to apply it to other rows. To identify matching rows, use =IF(A2=C2,"Match","Differ"). For columns in different sheets, utilize =A2<>INDIRECT("Sheet2!C2:C").

Conditional Formatting for Visual Comparison

Conditional formatting can be used to visually compare two columns in Google Sheets. Use the formula =COUNTIF($C$2:$C$9,$A2)>0 to highlight duplicates or =COUNTIF($C$2:$C$9,$A2)=0 to highlight unique values. Access conditional formatting options via Format > Conditional formatting, and apply rules with custom formulas.

Comparing Columns from Different Sheets

To compare columns from different Sheets, the IMPORTRANGE function can be used to bring data from other files. For checking duplicates across sheets, use =COUNTIF(INDIRECT("Sheet2!C2:C"), A2). These methods allow for seamless comparison between data across multiple documents.

Advanced Functions for Detailed Comparison

Use functions like MATCH and ISNA to find missing values between columns. =ISNA(MATCH(A1, B:B, 0)) returns TRUE if a value in Column A does not exist in Column B. Combine FILTER, MATCH, and ISNA to display only the missing values directly.

Creating Reports on Differences and Duplicates

To create detailed reports on differences and duplicates, use the formula =IF(COUNTIF(B:B, A1) >0, "Duplicate in B", ""). This marks duplicates in Column A found in Column B. Use VLOOKUP to match and compare values across columns or sheets.

Using Add-ons for Comparison

For more functionality, consider using add-ons to compare columns across multiple sheets or files. Add-ons provide additional features and can simplify complex comparison tasks, enhancing your workflow in Google Sheets.

How to Compare Two Columns in Google Sheets: Use Cases

Highlight Matching Cells in Two Columns

By using the formula =COUNTIF(B:B, A1) >0 in Google Sheets' conditional formatting, you can visually compare two columns and highlight cells in Column A that have matching values in Column B. This makes it easy to identify duplicates or common entries across the two datasets.

Identify Differences Between Two Columns

To find discrepancies between two columns, you can use the custom formula =COUNTIF(B:B, A1)=0. This approach will highlight cells in Column A that do not have a corresponding match in Column B, making it ideal for audits and data reconciliation tasks.

Mark Duplicates Across Columns

Using the formula =IF(COUNTIF(B:B, A1) >0, "Duplicate in B", ""), you can mark entries in Column A that are duplicated in Column B. This method is useful for identifying and handling redundant data entries effectively.

Extract Missing Values

By combining the MATCH and ISNA functions with the formula =ISNA(MATCH(A1, B:B, 0)), you can easily pinpoint values in Column A that are missing in Column B. This is especially useful for data validation and ensuring data completeness.

Compare Columns from Different Sheets

With the IMPORTRANGE function, you can compare columns from different Google Sheets files. Use the formula =IMPORTRANGE("spreadsheet_URL", "Sheet1!A1:A")=IMPORTRANGE("spreadsheet_URL", "Sheet2!B1:B") to identify matches or discrepancies across different datasets.

Highlight Unique Values Using Conditional Formatting

Create conditional formatting rules to highlight unique values in each column. For example, the formula =A2<>C2 can be used to highlight discrepancies, using colors to make unique values stand out for easy identification.

Automate Comparison with ARRAYFORMULA

Leverage the ARRAYFORMULA function to compare two lists without having to copy the formula down each row. For example, use =ARRAYFORMULA(IF(A2:A=C2:C,"Match","Differ")) to automate the comparison process and get a streamlined result.

VLOOKUP for Cross-Sheet Comparison

Utilize the VLOOKUP function in conjunction with conditional formatting to fetch and compare data across different sheets. This method is perfect for dynamic datasets where real-time comparison is crucial for data integrity.
