Calculate the growth rate to 0,001% precision.

You start with 100 and a year later you have 105. It is easy to figure out the growth rate there.
But what if you make monthly contibutions, or withdraw at random times?

Compares two snapshots of the same database and produces a line-by-line comparison.

You are given a database export in multiple CSV files. Next time you receive the same set and are asked "What changed?" Now it is your are tasked to go through several tables, houndreds or even thousands of rows and each of several dozens of cells, and mark down any changes.

There must be a better solution — there is!

Before using, you should:

• Have all your CSV files zipped together in a zip file.
• Identify all columns that uniquely identify a row (e.g. "Record ID", or a combination like "User ID" + "Test ID").
• Optionally define a sort order if records arrive in an inconsistent sequence.
• Optionally exclude columns that change constantly and are not relevant (e.g. "Last modified at").

Turns your set of CSV files into Excel

You are handed a large set of CSV files but your workflow requires Excel. Instead of opening each file and saving it as .xlsx one by one, this tool converts the entire set in one run — either as separate Excel files or combined into a single multi-tab workbook.

You have better things to do with your time, let the robots handle the conversion.
