The spreadsheets are Excel files and you must have Excel installed to use them.
I had worked up an Excel hack as a calculator, but Leladia has whipped up a most excellent calculator that runs as it's own program.
The following is a Hibernian trade reference library. Included in the information are mat counts, cost, salvage rates/cost, vendor buyback (actually tested each piece) effective AF or DPS of a piece by quality as well as spellcrafting points available by item at qualities 94-100. Town enchanter prices are also included for reference - or for further calculations by spellcrafters to compare.
Also included is a small calculator if you'd wish to use this to figure out pricing where you can set your desired markup and not round, round to silver or round to gold. (No calculator on scale due to the various methods of pricing).

12/4 - Updated Weapons with Scythes, spellcrafting with final receipes and epic armors with Valewalker and Animist pages - also added breakouts of armor only stats to epic armors.
12/6 - Added rough map for Grove of Domnann with NPC list and locations.
2/6 Fixed a small problem with the reinforced calculator % multiplier. Anyone using this sheet probably already noticed and fixed it. Only affected calculator page.
Updated weights on seige components to match the new weights (not yet on live).
2/26 Weights are now live - but ram weights have reverted back to original values and I haven't fixed the file yet - roughly double on metal parts.
A few patches ago Emerald and Sapphire Seal items in DF were also 'fixed' and yield roughly double what is in the file. Some bonuses may also have been adjusted - not checked yet.
Note on hats - they use the same receipes as their old counterparts - plus a 50c pattern.
