How to Compare Two Columns in Google Sheets for Matches

Using Conditional Formatting

To compare two columns in Google Sheets for matches, you can use conditional formatting to highlight duplicates. Select the range you want to compare, click on Format in the menu, and select Conditional Formatting. In the formatting options, choose Custom formula is from the Format cells if drop-down menu and enter the formula =COUNTIF($C$2:$C$9,$A2)>0 to highlight duplicates.

Using the IF Function

The IF function can set the status of whether two cells in the same row are the same or different. Enter =IF(A2=C2,"Match","Differ") to compare cells A2 and C2. Copy this formula down the column to compare other rows. For an array formula, use =ArrayFormula(IF(A2:A=C2:C,","Differ")) to automatically apply it to multiple rows at once.

Using the COUNTIF Function

Another approach is using the COUNTIF function. This can highlight unique or duplicate values. To highlight unique values, use the formula =COUNTIF($C$2:$C$9,$A2)=0. To highlight duplicates, use the formula =COUNTIF($C$2:$C$9,$A2)>0. These formulas can be used within the Conditional Formatting rules to visually indicate matches.

Using the INDIRECT Function

The INDIRECT function can be used to reference other sheets in your comparisons. Combine it with COUNTIF in conditional formatting to highlight matches. For example, use =A2=INDIRECT("Sheet2!C2:C") to compare values in column A of one sheet with column C of another sheet.

Using the MATCH and ISNA Functions

To find missing values, use the MATCH and ISNA functions. Enter =ISNA(MATCH(A1, B:B, 0)) to find cells in column A that do not have a corresponding match in column B. This formula will return TRUE for missing values and FALSE for matches.

Using Add-Ons

You can also use the Compare Sheets add-on to compare and highlight duplicates or unique values between columns within one Google sheet or across different files. This tool simplifies the process and provides a visual comparison using colors.

Using the VLOOKUP Function

The VLOOKUP function is useful to compare columns and highlight matches. By setting VLOOKUP to search for values from one column in another, you can identify and highlight duplicate entries effectively.

Using the QUERY Function

The QUERY function allows you to compare values in two columns across different tabs. This function is powerful for more complex comparisons and data analysis.

Comparing Google Sheets and Sourcetable

Google Sheets is a powerful spreadsheet tool widely used for various data tasks. It offers robust features, but advanced tasks like writing complex formulas and SQL queries often require in-depth knowledge and significant time investment.

Sourcetable, an AI-first spreadsheet, significantly enhances efficiency. Unlike Google Sheets, Sourcetable comes with an AI assistant that writes complex spreadsheet formulas and SQL queries, saving users time and effort. This feature makes advanced spreadsheet tasks accessible to anyone, regardless of their technical expertise.

Another advantage of Sourcetable is its integration capabilities. It connects with over five hundred data sources, allowing users to search and ask any questions about their data within the same platform. Google Sheets lacks this extensive integration, making data collation from multiple sources more cumbersome.

For tasks like comparing two columns for matches in Google Sheets, users often search for how-to guides and spend time manually writing formulas. Sourcetable simplifies this process. The AI assistant can generate these complex formulas instantly, providing answers efficiently without the need for extensive search or manual formula typing.
