![]() ![]() Select A1:D10 and apply it as instructed earlier. We want to highlight new line duplicates row-wise. This time we have a few records in the range A1:D10, which means in multiple rows and columns. We require to modify the regular expression part, which is part_2_a. The above formula won’t support highlighting duplicates in new lines across rows. How do we apply the above formula in a table? How Do We Find Duplicates in New Lines Inside Cells Across Rows? That’s the logic behind finding duplicates in new lines in a column in Google Sheets. Logic:- Part_1 doesn’t match part_2_a means it already appears in the range in new lines. Part_2_a: The distinct values in new lines up to the current row. ![]() Part_1: The new line value in the current row. =ArrayFormula(not(regexmatch(part_1,part_2_a))) Our final REGEXMATCH formula that finds duplicates in new lines in a column is as follows. We are ready to highlight duplicates in new lines inside cells in a column. The TEXTJOIN combines the extracted part_2 values and forms a regular expression. The purpose of part two is to create a regular expression. The IFNA removes #N/A errors, and UNIQUE gets distinct values (values that do not repeat). Here are the other changes compared to part_1. The first cell is absolute, and the second cell is relative. The cell range in the above formula part becomes $A$1:$A2, $A$1:$A3, $A$1:$A4, in the cells down. Nesting of ARRAYFORMULA is not necessary for most of the Google Sheets formulas. Note:- In the rule that highlights duplicates in new lines, you will only see the above-bolded part. Here is a similar formula for $A$1:$A1, with additional modifications. So it will automatically become A2, A3, A4, and so on in the selected cells down in Conditional formatting. Please note we have used A1, the first cell in the range and relatively referenced. We should trim the result to remove any additional white space characters. Using REGEXEXTRACT, we can extract any characters after the linefeed (newline) character. ![]() The first thing to do is extract the value in the second line from cell A1. We can peel the above rule and see how each part help to highlight duplicates in new lines inside cells in A1:A in Google Sheets. Anatomy of the Rule: Extracting Second Line Values in Cells and Analyzing It will highlight cells in column A wherever duplicate values appear in new lines within each cell. Choose the formatting style you want to apply to the duplicates in new lines in the selected cell range.įormula Rule (Column): =ArrayFormula(not(regexmatch(trim(regexextract(A1&"","\n.*")),"^"&textjoin("$|^",1,unique(trim(ifna(regexextract($A$1:$A1&"","\n.*"))),false,true))&"$"))).Replace A1 and $A$1:$A1 with the first cell in your selected range.In the “Value or formula” field, enter the formula given immediately after the seventh step below.In the “Format cells if” dropdown menu (immediately under the “Format rules”), select “Custom formula is.”.Go to the “Format” menu, then choose “Conditional formatting.”.Select the cell range you want to check for duplicates in new lines.Please modify it to find/highlight duplicates within cells in a different range. The following steps are for the range A1:A. You can use the built-in conditional formatting feature to highlight duplicates in new lines inside cells in a column in Google Sheets.
