I don't think you can do it directly from a CSV. But, if you imorpt the whole CSV and save it as an HTML table, you can use that table as a Spry Data Source. Here are the steps:1. Import CSV into n HTML table following this tutorial2. Give the table an ID, i.e. id= data 3. Save the file. i.e data.html4. Create a new HTML file and go to Insert->Spry->Spry Data Set5. A three step wizard will launch that will help you with the rest.6. On the last step of the process make sure to click the  Set Up  button, which will help you pick the columns :)I know it's not as simple, but you may like the result!

function readBytesLocal(Address, ByteCount, [ReturnAsTable])

Reads bytes from the specified address in Cheat Engine's own process memory (not the target process). Returns the bytes as multiple return values or as a table if ReturnAsTable is true.

Function Parameters[edit]

Parameter Type Description
Address Integer or CEAddressString The address in Cheat Engine's memory to read from.
ByteCount Integer The number of bytes to read.
ReturnAsTable Boolean (optional) If true, returns a table of bytes. If false or omitted, returns each byte as a separate return value.

Examples[edit]

-- Read 4 bytes and get them as separate values
local b1, b2, b3, b4 = readBytesLocal(0x123456, 4)
print(b1, b2, b3, b4)

-- Read 4 bytes and get them as a table
local bytes = readBytesLocal(0x123456, 4, true)
for i, v in ipairs(bytes) do
  print("Byte " .. i .. ": " .. v)
end
