Hi . My database seems to be somehow encrypted by the software I used. When I try to export my data some fields are encrypted like this:
1 => 31911
2 => 63758
3 => 95540
4 => 127258
5 => 158912
6 => 190504
7 => 222032
8 => 253498
I'm really sure it's not some complicated formula (because I managed to recover other fields) . I just want to reverse the formula used to "encrypt" this data.
Thank you. Excuse my english.

What software are you using?

i really don't know what software made this kind of encryption. i'm trying to migrate to mysql for now.

What does the data represent? Those numbers?
You might have better luck posting on an encryption forum or a newsgroup like comp.sci.cryptography.

This data represents no. of employees for each company listed in the website.

It appears to be near sequential in nature, with a multiplication factor ...
31911/1 = 31911
63758/2 = 31879
95540/3 = 31847
127258/4 = 31814
158912/5 = 31782
190504/6 = 31750
222032/7 = 31718
253498/8 = 31687
Does this number (~31800) look familiar?
Also (given my rounding)
31911 - 32 = 31879
31879 - 32 = 31847
31847 - 32 = 31814
31814 - 32 = 31782
31782 - 32 = 31750
etc.
Its too early for me to write the formula, but it appears there is one. Something like (n * 31943) - 32 = x
