    How to lock cells to Excel in formulas

    When you compose a formula on Excel, in almost all cases you use cell references to automatically acquire the data already present in the sheet. If the formula has to be repeated several times, the operation that you surely put into practice is to drag the cell that contains it into those below or adjacent to it.

    By carrying out this procedure, however, what happens is that the reference of the rows or columns of a cell is translated. Although in some cases this consequence can be useful, in others there is the risk of creating errors in the calculation of the formulas, especially for those that repeat themselves but have static values ​​taken from a single cell or from a specific range.

    To solve this drawback, it is necessary lock cells in formulas, so that their references cannot in any way be translated. This operation is possible only by entering the $ symbol within the cell reference. Let's see in detail how to do it.

    Let's take the cell as an example C2, inside which the simple formula was typed = POWER (B2: A2) (to calculate the power of a value equal to A2 on the number present in B2).

    In the column B you therefore have a series of values ​​on which to calculate the power and in the column C you need to repeat the formula as many times as there are values ​​in B. By dragging the formula down, the cell B2 contained in the formula would be replaced with B3, then with B4 and so on, so that the cell reference follows the values ​​in the table in column B. As for A2instead, dragging would cause the cell reference to be transformed into A3 and progressive, with the consequent error in the formula as the value is present only in A2.

    To fix this, you simply need to transform the cell A2 in $ A $ 2, prefixing the $ symbol on both the column reference and the row reference. You can also edit the formula and place the typing pointer on the cell and press the key F4 repeatedly, until complete blockage occurs, as I have indicated to you. Once the cell is locked, any horizontal or vertical dragging will leave the cell reference unchanged in subsequent formulas.

    Another case that can occur is when you need to block the reference of only the column or row of a cell. In this case, the procedure to follow is similar to the one I showed you in the previous paragraphs: affix the $ symbol on the column reference (ex. $ A2) or on that of the line (eg. A $ 2) to lock the column or row of a cell respectively within the formula.

    The consequences of what I have illustrated to you are the following: in the event that you have blocked the column (eg $ A2), in case of horizontal dragging of the formula the reference will remain on column A, but by dragging the formula vertically the row reference will change (e.g. $ A3, $ A4, etc.). If you have blocked the line (ex. A $ 2), if the formula is dragged vertically the reference will remain on row 1, but by dragging the formula horizontally the column reference will change (e.g. B $ 3, C $ 4, etc.).

    How to freeze cells in Excel scrolling

    When working in Excel with a large amount of data, it is often necessary that some cells, such as those relating to the column header, are locked during scrolling, so as to avoid going back to the beginning of the sheet to understand each column. what you are referring to.

The option Freeze Panes, on the other hand, it allows you to freeze multiple rows or multiple columns, unlike the other two options I told you about, which are limited only to the first row / column of the sheet.

    To use the latter feature, select the row or column next to the range you want to block and press the option Freeze Panes, to confirm the display lock. To clarify, if you want to block the range of lines A1: A3, you need to select the whole row A4 and then click on the option Freeze Panes.
