Hi Creztor
Sorry I don't know of any way to acquire MT4 to do this.
Here's a possible workaround:
1. Download FREEWARE text editor EmEditor from http://shareme.com/download/emeditor-free.html
and then run the .MSI file to set up (into \Program Files\EmEditor)
Then run EmEditor
2. Open the document (press Ctrl-O) whose dates you wish to modify.
3. Press Ctrl-H for search/replace, and assess Use Regular Expressions ON.
Type precisely
^(...)\. (. .) \. (. .)
To the Find field, and
\two-\3-\1
into the Replace with field
[NOTE: this presumes you want to change to format MM-DD-YYYY; change the hyphens to whatever separator you need; also change 1,2,3 around however you wish: 1=YYYY, two=MM, 3=DD, e.g. to obtain DD/MM/YYYY, kind
\3/\2/\1
make certain the backslashes \ stay where they are]
Click on Replace All, and then press Esc to close search/replace, and Ctrl-S to store the document.
4. Repeat steps 2 to every document, as required. Note your entries in the Find and Replace with stay sticky: you only ever need to sort them once. EmEditor also recalls the folder from which you opened the last CSV file.
You could rather load the files into Excel and manipulate using formulae, but - once the Find and Replace with entrances are set up in EmEditor - it's considerably faster. It's extremely fast and easy once you've done it a couple of times.
Hope this helps.
