How to Import Data from Text and Access Files into Excel

Importing Data from a Text File

• The process begins by navigating to the "Data" tab in Excel and selecting "From Text" to import data from an external text file.

• After selecting the text file, a series of prompts will appear asking how to organize and structure the imported data based on delimiters like tabs or commas.

• Users can specify whether to separate columns based on tabs or other characters, with a preview feature showing how the data will be divided.

• Once the delimiter is set (e.g., tab), users confirm that their columns are correctly organized before finishing the import process.

• The imported data appears in Excel, formatted according to the specified delimiters, allowing for easy manipulation within the existing worksheet.

Importing Data from an Access File

• To import data from an Access database, users select their Access file directly; this interface differs as it recognizes fields and records automatically.

• Unlike text files, no additional prompts for delimiters are needed since Access structures its data in tables with defined columns and rows.

• The imported Access data is displayed as a formatted table in Excel, maintaining its original structure without requiring further adjustments.

• Users have options to convert table formatting back into regular cells if desired or modify it according to their needs.

Advanced Data Manipulation Techniques

• If further separation of column data is required (e.g., splitting combined values), users can utilize the "Text to Columns" feature under the "Data" tab.

• This tool allows specification of new delimiters for separating content within a single column into multiple columns based on user-defined criteria.

• A warning message may appear if existing cell contents would be overwritten during this operation; caution is advised not to lose any pre-existing data.

• It’s essential first to ensure there are enough empty columns available for new data before executing splits; otherwise, existing information could be lost.

How to Split and Merge Columns in Excel

Splitting Data into Separate Columns

• The speaker demonstrates how to split a column of data in Excel using the Text to Columns feature, selecting either tab or comma as delimiters.

• If there are empty columns available, Excel will place the separated data without issues; however, if there is existing data, it prompts an error message.

Merging Two Columns into One

• To combine first names and last names into a single column labeled "Full Name," a new empty column must be added first.

• The speaker explains how to use a simple formula (e.g., C2 & " " & B2) to concatenate two cells while ensuring proper spacing between them.

Correcting Formula Errors

• An initial mistake in the formula results in no space between combined names; thus, it's crucial to specify separators correctly within the formula.

• The correct method involves using quotation marks for spaces or other characters that need to be included as separators.

Finalizing Combined Data

• After correcting the formula by adding necessary spaces or characters, dragging down the fill handle updates all rows accordingly with proper formatting.

• Once satisfied with the merged data, unnecessary original columns can be deleted without affecting the final output since it now contains only values.

Handling Deletions and Maintaining Values

• If original columns are deleted after merging, any formulas referencing those columns will break. Therefore, copying and pasting values is essential for maintaining integrity.

• Using Paste Special allows users to keep only final values instead of formulas when transferring merged data elsewhere.

Additional Features: Adding Hyperlinks

Creating Hyperlinks in Excel

Linking to Other Sheets and Files

• The speaker discusses creating hyperlinks within an Excel file, allowing users to navigate between different sheets or external files easily.

• Users can create links not only to other sheets but also to web pages, emails, or any relevant documents that provide additional data related to the current content.

• An example is given where a cell can display a word (e.g., "our site") that, when hovered over with the mouse, shows a tooltip prompting the user to click for more information.
