A constant is a set value that doesn’t change and that’s directly inserted into a cell. It’s not a formula and it’s not calculated by a formula.

Cell content. Information such as numbers, text, dates, or times of day that you type into a cell. Formula.

A cell reference, or cell address, is an alphanumeric value used to identify a specific cell in a spreadsheet.

A cell range in an Excel file is a collection of selected cells. This range is usually symmetrical (square), but can exist of separate cells just the same. A cell range can be referred to in a formula as well. Eventually separate cells can be added to this selection, then the range is called an irregular cell range.

Answer. Explanation: Colon ( : ) – This is used to define a range of cells (e.g. “A1:D4”). A range of cells is described in terms of the top left cell and the bottom right cell references separated by a colon.

How-to handle more than million rows in Excel? You may know that Excel has a physical limit of 1 million rows (well, its 1,048,576 rows). But that doesn’t mean you can’t analyze more than a million rows in Excel. The trick is to use Data Model.

CSV files have no limit of rows you can add to them. Excel won’t hold more that the 1 million lines of data if you import a CSV file having more lines. Excel will actually ask you whether you want to proceed when importing more than 1 million data rows.

Excel contains over one million rows – 1,048,576 to be exact. If your file is larger than that and you will try to open this file in Excel, you are going to get the following message. After you click OK, you can move to the last row (Ctrl + Down Arrow) and see that the worksheet is filled to the last row.

The size of the CSV also depends by the encoding of the file. Check also the encoding for the two CSV files that you have. 2. Create a new sheet, create formulas that points to the first sheet, export this new sheet as CSV.

In a xlsx you can save the formulas, graphs, pivots, etc in the file. A CSV is just a flat text file that uses a delimiter to separated the fields, e.g. Although Excel can read the fileformat and you can use formulas in it, you cannot save the formulas in the sheet. Excel will only save the result of the calculation.

It is also possible that changes in any macros attached to the workbook could have greatly increased the file size. It could also be due to adding a PivotTable or changing how the PivotTable is saved within the workbook. Finally, if you changed the format used to save the workbook, then the file size can increase.

Now, there are two ways you can reduce the file size when working with Pivot tables.

1. Keep the source data and delete the Pivot Cache.
2. Keep the Pivot Cache and delete the source data.

optimising formulas.

1. Remove “blank space” in your sheets.
2. Check for and delete unnecessary hidden sheets.
3. Save your files in binary format (.xlsb)
4. Remove formatting on raw data.
5. Double check Conditional Formatting ranges.

There is no way you could reduce size of CSV format output. What is the size of the CSV file? You can open that file in excel.

Excel is an amazing tool for analyzing and visualizing data sets. It is important to have small size of excel file. The first reason is loading time. If your excel file is large (2 mb or larger) you will notice longer loading time, reduced performance, unresponsiveness, etc.

Another reason for large file size is having many unused or hidden worksheets in your Workbook. Each Excel Worksheet has it’s own share of metadata, more importantly, however, you may be keeping sheets with similar datasets, copies or unnecessary Pivot Tables that also take up a lot of space.

In the 32-bit version of Office, the maximum files size for a workbook containing a Data Model is 2 GB, and the maximum memory that can be consumed by a workbook is 4 GB. If you exceed either of these limits, the workbook cannot be saved.

The biggest reason for slow Excel files are formulas that take too long to calculate. This means your file won’t hang for a long time before you can continue working. To turn on manual formula calculation, in the Excel Ribbon go to Formulas > Calculation > Calculation Options > Manual.

Although memory does not affect Excel’s calculation or manipulation speed, the size of your database (number of columns and rows used) is affected by the amount of available RAM in your system. Remember, just because your computer has 8GB of RAM, that doesn’t mean you have that much available to work with.

Volatile formulas are called so because of a reason. For example, if you use NOW function in a cell, every time there is a change in the worksheet, the formula would be recalculated and the cell value would update. This takes additional processing speed and you end up with a slow excel workbook.
