I need an OCR tool

Hi everyone. I try to explain as easily as I can what I need. FOR WINDOWS 10, or for Windows in general. I need to read and collect all the ID numbers of a really high (thousands) of invoices, which have been converted by paper in PDF or jpeg. I thought to collect all che ID in a csv file. I need a OCR software which is very similar to the famous ABBYY but i need some specs. 1st the screenshot/OCR area on the screen should be chosen one time only and should be the same for infinite screenshots, no need to re-set every time the area. 2nd I need to collect all the reading in a csv or txt. 3rd I need to set a cronometer for every screenshot and reading (ex. every 3 seconds) or a timer 3..2...1.... screehshot and reading…..3...2...1... screenshot, forever. 4th I need to have a click function just like autoclicker, for changing pictures if jpegs or change pdf if PDFs. I would like to point the mouse pointer on the changing file button and leave it there, then auto clicking. I may need to choose between right click or right arrow for changing file too, it depends on the software I'm using to read invoice files. For clarity I would need the suqsequent process: start..3...2...1...(screenshot/read/collect in csv)….2....1....right click(or right arrow)change pic or pdf….3...2...1 (for loading)……(screen/read/collect in csv)…..1.....etc. infinite loop The timer is necessary for file loading, then I would adjust depending on the actual loading time between one file and another. I no need to change screenshot area because the files are luckily all similar and the code I need is always in the same place, this is very important, otherwise I would not be able to read files automatically. In short word, I need a timered OCR software with a timered autoclicker (timers have to be paired) within a selected area on display. Anyone could help me? I'm here for every question. Thank you very much.
