Convert Excel to PDF

Whenever you need to share an important Excel report with a partner, it's best to convert the file to PDF to ensure it looks the same as it does on your device.

Export Data from Database to Excel

When data is exported from a database to Excel, it can be analyzed and visualized, as well as viewed and processed by users who are not database users.

Apply Data Validation

Data validation in Excel controls what kind of data can be entered into a certain cell, which ensures that all data entries are accurate and consistent.

Insert Formulas and Functions

Formula is an expression that calculates values in a cell or in a range of cells, while function is a predefined formula already available in Excel. Both formulas and functions are very useful when you need to calculate numbers or solve math problems in Excel.

Apply Conditional Formatting

Conditional formatting is a helpful feature that allows applying special formats to cells meeting specific criteria. It is often used to emphasize or differentiate data stored in worksheets.

Create a Chart

Chart is a fantastic tool to visually group and analyze data. It provides the reader with the structure of the data set and displays the data in a graphical representation, making it easier for most users to see the data.

Create a Pivot Table

Pivot table is a kind of interactive table that allow users to quickly categorize, calculate, summarize and analyze large amounts of data in a concise tabular format.

Group Rows or Columns

For worksheets with large amounts of data, grouping rows or columns that contain similar information can make the worksheet more compact and understandable.

Merge Excel Files

Merging Excel files with associated content can help us work with worksheet data more easily and also make it easier to share and read the contents of our workbooks.

Find and Highlight

You can find all cells containing a specific value and highlight them with the same background color to make the value outstanding and more easily to be found out.
