How to Insert Blank Rows to Separate Week Starts/Ends in Google Sheets

GiGiKing·March 26, 2024·0 comments

Have you ever wanted to insert blank rows to separate week starts or ends in Google Sheets? It can be a great way to improve readability and make your reports look cleaner when printed. But manually doing this for a large dataset can be tedious. That’s where our formulas come in to automate the process for you.

Inserting Blank Rows at Every Week Change

The first perspective we’ll approach is inserting blank rows at every week change row in existing data. This formula has the following key features:

  • Array formulas
  • No helper cells required
  • Customizable number of blank rows to insert
  • Option to choose any day of the week as the separator

To use this formula, follow these steps:

  1. Select the range of cells that contains your data, excluding the header row.
  2. Determine the range of cells that contains the header row.
  3. Identify the range of cells that contains the date column.
  4. Choose the day of the week that you want to use as the separator. Use one of the numbers from 11 to 17, where 11 represents Monday and 17 represents Sunday.

Here’s the formula you can use:

=ARRAYFORMULA(LET(
range, A2:D,
header, A1:D1,
dt, B2:B,
at, 11,
helper, WEEKNUM(DATEVALUE(dt),at),
REDUCE(header,TOCOL(UNIQUE(helper),3),
LAMBDA(a,v,IFERROR(VSTACK(a,FILTER(range,helper=v),))))
))

If you want to insert a blank row to separate weeks that start on Sunday and end on Saturday, simply replace the number 11 in the formula with 17.

Inserting Two Blank Rows Below Each Week Change

If you’d like to insert two blank rows below each week change in a date column, just add one more comma to the last part of the formula. Here’s an example:

=ARRAYFORMULA(LET(
range, A2:D,
header, A1:D1,
dt, B2:B,
at, 11,
helper, WEEKNUM(DATEVALUE(dt),at),
REDUCE(header,TOCOL(UNIQUE(helper),3),
LAMBDA(a,v,IFERROR(VSTACK(a,FILTER(range,helper=v),,))))
))

These formulas are flexible and can be customized to meet your specific needs.

Generate a Sequence of Dates and Separate Week Starts/Ends

In some cases, you may want to generate a sequence of dates and separate week starts/ends with one or more blank rows. You can achieve this by replacing the data range with a SEQUENCE formula. Here’s an example:

=ARRAYFORMULA(LET(
range, SEQUENCE(100,1,A1),
header, "text",
at, 11,
helper, WEEKNUM(range,at),
REDUCE(header,TOCOL(UNIQUE(helper),3),
LAMBDA(a,v,VSTACK(a,FILTER(range,helper=v),)))
))

In this example, the formula will generate a sequence of 100 dates in sequential order starting from the date specified in cell A1. The dates will be separated by blank rows at the week start.

Now you have the power to easily insert blank rows to separate week starts or ends in Google Sheets. These formulas will save you time and effort, making your data more organized and visually appealing.
