How to use Vlookup in MS Excel - step by step tutorial

 The VLOOKUP (vertical lookup) function in Excel allows you to search for a specific value in a table and return a corresponding value from a different column in the same row. Here is a step-by-step guide on how to use the VLOOKUP function in Excel:

Create a table with the data you want to search through. Make sure that the first column of the table contains the values you want to search for (the "lookup value").

In the cell where you want the result of the lookup to appear, type the formula =VLOOKUP(

The first argument you need to provide to VLOOKUP is the lookup value. You can enter this value directly into the formula, or you can reference a cell that contains the value. For example, if the lookup value is in cell A1, you would enter A1,

The second argument is the range of cells that contains the table you want to search through. You can either enter the range directly into the formula (e.g. A1:D10) or you can name a range and use the range name (e.g. table1).

The third argument is the column number in the table that contains the value you want to return. For example, if you want to return the value in the third column of the table, you would enter 3,

The fourth argument is an optional logical value (TRUE or FALSE) that specifies whether you want an exact or approximate match. If you want an exact match, you would enter FALSE, if you want an approximate match, you would enter TRUE (default value is FALSE)

Close the formula with a closing parenthesis )

For example, the formula =VLOOKUP(A1,A1:D10,3,FALSE) would look for the value in cell A1 in the first column of the table located in the range A1:D10, and return the value in the third column of the same row.

Note: Make sure that the first column of your table is sorted in ascending order, otherwise VLOOKUP will return unexpected results.

How to use in Smartphone/Mobile phone?

The VLOOKUP function can also be used in the Excel app on a smartphone, but the steps may be slightly different due to the smaller screen size and touch interface. Here is a step-by-step guide on how to use the VLOOKUP function in Excel on a smartphone:

Open the Excel app on your smartphone and open the spreadsheet that contains the data you want to search through.

Tap on the cell where you want the result of the lookup to appear.

Tap on the "fx" button to open the formula builder.

Type "VLOOKUP" into the search bar and select it from the list of formulas.

In the function arguments, enter the lookup value. You can either enter this value directly or tap on the cell that contains the value to reference it.

Next, enter the range of cells that contains the table you want to search through. You can either enter the range directly or tap on the first cell of the table and drag your finger to select the entire table.

Enter the column number in the table that contains the value you want to return.

Tap on the "checkmark" button to apply the formula and complete the function.

Press Enter to see the result.

Note: Make sure that the first column of your table is sorted in ascending order, otherwise VLOOKUP will return unexpected results. And also, in smartphones, some of the steps may vary depending on the device and excel app you are using.

What is Chat GPT and how to use Chat GPT in Smartphone and PC

What is Chat GPT? 

ChatGPT is a variant of the GPT (Generative Pre-trained Transformer) language model developed by OpenAI. It is a neural network-based model that has been trained on a large dataset of text data and is capable of generating human-like text. ChatGPT is optimized for conversational language and can be used for a variety of tasks such as generating responses in a chatbot, summarizing text, and completing sentences or paragraphs. The model can also be fine-tuned on specific tasks or domains, such as customer service or technical support, to improve its performance in those areas.

Specialties of Chat GPT?

ChatGPT has several specialties that make it well-suited for conversational language tasks:

Contextual understanding: ChatGPT has been trained on large amounts of conversational data, allowing it to understand the context of a conversation and generate more appropriate responses.

Human-like language generation: The model is able to generate text that is grammatically correct and sounds similar to text written by a human.

Flexibility: ChatGPT can be fine-tuned on specific tasks or domains, such as customer service or technical support, to improve its performance in those areas.

Multi-language Support: ChatGPT can support multiple languages and can generate text in different languages, it can also understand different languages and generate responses accordingly.

Large-scale pre-training: ChatGPT is pre-trained on a massive amount of text data, which makes it more powerful than other models.

Low-latency: ChatGPT can generate a response in milliseconds, which makes it suitable for real-time chatbot applications.

How to use Chat GPT on Smartphone/Mobile phone?

To use ChatGPT on a smartphone, you will need to use an app or program that allows you to interact with the model through an API. One example of such an app is the OpenAI GPT-3 Playground, which can be accessed through a web browser on a smartphone. Additionally, you can use the Hugging Face's API to make requests to GPT-3 model, and then use it in your mobile app. This can be done by integrating their API library into your mobile application.

How to use Chat GPT on Desktop PC/Laptop?

To use ChatGPT on a laptop or PC, you can use the OpenAI API to interact with the model and generate text. Here is an example of how you can use the OpenAI API to generate text using Python:

First, sign up for an API key from the OpenAI website.

Install the OpenAI Python library by running pip install openai in the command line.

Import the openai library in your Python script.

Use the openai.Completion.create() function to make a request to the API and generate text. You will need to pass in your API key and specify the prompt (the text you want the model to complete or generate a response to) and the model you want to use (in this case, "text-davinci-002").

python

Copy code

import openai

openai.api_key = "YOUR_API_KEY"

prompt = "What is ChatGPT?"

completions = openai.Completion.create(

    engine="text-davinci-002",

    prompt=prompt,

    max_tokens=1024,

    n=1,

    stop=None,

    temperature=0.5,

)

message = completions.choices[0].text

print(message)

Additionally, you can use the Hugging Face's API library to make requests to GPT-3 model, and then use it in your Python script by installing the transformers library.

You can also use the OpenAI GPT-3 Playground, which is a web-based interface that allows you to interact with the model and generate text. You can access the playground through a web browser on your laptop or PC.
