How to Compare Two Lists in Google Sheets

Using Formulas

Use the formula =A2=C2 to compare two lists in Google Sheets by checking if the cells in column A match those in column C. Copy the formula down to other rows to compare entire columns. For a neat solution, use =IF(A2=C2,"Match","Differ") to set the status of each cell as "Match" or "Differ". To compare without copying the formula to each row, use =ArrayFormula(IF(A2:A=C2:C,"","Differ")).

To compare lists in different files, use the IMPORTRANGE function along with the formula =IF(Sheet1!A1=IMPORTRANGE("2nd_spreadsheet_url","Sheet1!A1"),Sheet1!A1&" | "&IMPORTRANGE("2nd_spreadsheet_url","Sheet1!A1"),""). Use the formula =IF(Sheet1!A1>Sheet2!A1,Sheet1!A1&" | "&Sheet2!A1,"") to compare two Google Sheets.

Using Conditional Formatting

To highlight duplicates or unique values, use the COUNTIF function combined with conditional formatting. Use =COUNTIF($C$2:$C$9,$A2)=0 to highlight unique values and =COUNTIF($C$2:$C$9,$A2)>0 to highlight duplicates. The formula =AND(A2=C2,ISBLANK(A2)=FALSE) can also be used to compare lists directly.

Conditional formatting can be used to find differences between two lists by creating a rule for each list. Apply COUNTIF with the condition =0 to find uniques or with the condition >0 to find duplicates.

Using Add-Ons

The Compare Sheets add-on for Google Sheets enables the comparison of lists, columns, or sheets and highlights duplicates or uniques. Multiple tables can be compared at once using this add-on.

Advanced Techniques

Use the INDEX MATCH MATCH formula to compare two lists and return the position of matching values. VLOOKUP can be used in combination with MATCH to compare two lists and return corresponding values for matched strings.

Combining Functions

Use the QUERY function to compare lists in different sheets. The SUMIFS and UNIQUE functions can return the sum or difference of values when comparing two lists. Indirect referencing (INDIRECT function) with COUNTIF helps to check for duplicates across sheets.

How to Compare Two Lists in Google Sheets: Use Cases

1. Identifying Matching and Non-Matching Data

By utilizing the =IF(A2=C2,"Match","Differ") formula, users can compare two lists in Google Sheets row by row. This formula returns "Match" if the values are the same and "Differ" if they are different, allowing for a neat and organized comparison. Additionally, the ArrayFormula function can automate this process across an entire column, removing the need to copy formulas manually.

2. Comparing Data Across Different Files

The IMPORTRANGE function enables users to compare lists from different Google Sheets files. For example, the formula =A2=IMPORTRANGE("spreadsheet_url","Sheet1!A2") allows users to compare values from two separate files efficiently. This is essential for businesses managing data across multiple spreadsheets.

3. Using Conditional Formatting to Highlight Differences

Conditional formatting techniques can highlight duplicates or unique values in two lists. By applying the =COUNTIF function with custom formulas, users can visually identify matching or unique records. This visual approach is valuable for quickly spotting differences without manually scanning the data.

4. Finding Missing Data with VLOOKUP

The VLOOKUP function helps in locating missing entries between two lists. For example, using =IF(ISNA(VLOOKUP(D2,PList!$E$2:$E$5000,1,FALSE)),"NOT RECIEVED","RECIEVED"), users can verify if items in one list are missing in another, providing clarity on data discrepancies.

5. Counting Matches Across Lists Using SUMPRODUCT

The SUMPRODUCT function, combined with COUNTIF, can be used to count the number of matches between two lists. For example, the formula =SUMPRODUCT(COUNTIF(D2,PList!$E$2:$E$5000)) provides a quick tally of matching data, which is useful for statistical analysis.

6. Merging and Updating Data with Add-Ons

Add-ons like Merge Sheets can be used to compare, merge, and update multiple sheets. These tools are especially useful for extensive datasets where manual comparison would be impractical. They can highlight duplicates, uniques, and handle multiple tables simultaneously, streamlining data management tasks.

7. Highlighting Duplicates Across Sheets

Using the INDIRECT function with conditional formatting, users can compare lists across different sheets. For instance, applying =A2=INDIRECT("CNA!A2:A") in a conditional formatting rule can highlight duplicates, offering a straightforward visual method to identify overlapping data in separate tabs or sheets.

8. Running Large-Scale Comparisons Efficiently

Combining UNIQUE, ARRAYFORMULA, and VLOOKUP functions, users can perform large-scale comparisons between extensive lists. This method ensures only unique values are considered, and by including array formulas, the comparison process is streamlined, reducing the overhead of manual checks.
