Hello,
I’m a senior MS-Access developer, working exclusively with Access and related programs such as Word, Excel, and Outlook. Also Python. Access is my passion - what I focus on and am very good and experienced at having built ~100 databases including my 70 jobs on Upwork.
You don't say what kind of database you are working on. What did you mean by limitation? If the data is consistent within fields, then there should not be any limitation regardless of the back end. Maybe some massaging of the data might be required to get rid of non-ascii characters, unwanted whitespace or whatever, that is all.
I noticed you put "Python" in the skill set. Python is a good choice to do this. It has an ODBC connector.
Feel free to contact me with any questions or concerns for a free consult. I’m available by PM, email, Skype and a US telephone number.
