With AWS Lambda, you pay only for what you use. You are charged based on the number of requests for your functions and the time your code executes. AWS Lambda is now generally available. The AWS Free Tier includes 1 million free requests and up to 3.2 million seconds of compute time per month with AWS Lambda.
To export data from Excel to a text file, use the Save As command. Delimited text files (.txt), in which the TAB character (ASCII character code 009) typically separates each field of text. Comma separated values text files (.csv), in which the comma character (,) typically separates each field of text.
CSV (Comma Separated Value) was a file format devised to store tabular data. It uses commas to separate each entry in a row and the newline symbol to go to the next row. Excel is a more recent spreadsheet application from Microsoft and it saves the data with its own file format. Excel is way more superior compared to CSV as it is able to do a lot more to the tabular data. Formatting is one of the biggest feature that comes with newer spreadsheet applications.
