stdVBA
VBA Standard Library  A Collection of libraries to form a common standard layer for modern VBA applications.

InfluxDB
Power RealTime Data Analytics at Scale. Get realtime insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in realtime with unbounded cardinality.

VBACSVinterface
The power you need to cleanse, filter, sort, reshape, manage and analyze data from CSV files.

VBAExpressions
A powerful string expression evaluator for VBA and LO Basic, which puts more than 100 mathematical, statistical, financial, datetime, logic and text manipulation functions at the user's fingertips.
At that point, I decided to try the fabulous stdLambda tool, developed by u/sancarn. I found that stdLambda correctly evaluated all the corner cases that made Volpi's class fail. This fact excited me, so I decided to measure the time it took to evaluate an expression with variables, noticing that the u/sancarn library was quite efficient. At that point, I started to measure the performance by evaluating functions like sin, cos, tan, abs, the results seemed strange to me when I noticed that the performance was almost 50 times lower when compared to the results obtained when measuring the performance by evaluating expressions without calls to builtin functions.
In spite of what I discovered, I was convinced that I could incorporate the referred library to CSV Interface, so I dedicated myself to study the methodology with which variables are handled in stdLambda. I found it difficult to understand why the variables must be passed in terms of a preestablished order ($1 refers to the first value passed as parameter of the evaluate function, $4 the fourth... and so on). Thus, the user is forced to write the expressions taking into account the order in which the values will be passed.
After a long search for something similar to the above, I decided to experiment and test the veracity of a warning that read: "... rather, it evaluates the infix expression directly. This approach is slightly more complicated than the traditional one". Then, I chose to develop an evaluator with its own grammar and a different approach to handle mathematical expressions. The solution I came up with is so called VBA Expressions. With VBA Expressions we can evaluate a variety of mathematical expressions, being able to work with arrays defined by text strings as in Java. A notorious feature is the ability to work with variables (Pi.e * 5.2Pie.1 + 3.1Pie), constants (3pi+ln(2e)), floating point numbers ((1.434E3+1000)*2/3.235E5) and Boolean values (x>0 & Sqr(xLn(2))>=3  tan(x)<0).
