Convert X83 to X84
In goes the invitation to tender as X83 (or D83, P83), out comes your bid as X84. You enter your own unit prices, in the browser or in an Excel price sheet; the converter computes item totals, section totals and the net total and refuses to write an X84 while a price is missing.
Beta: check every X84 in your own tendering software before you submit it.

How it works
How to turn an X83 into an X84
01
Drop the X83 into the converter.
02
Enter a unit price for every item, or export the price sheet, fill in the yellow column in Excel and load it back.
03
Enter your company name and address; an X84 must name the bidder.
04
Read the report, download the X84 and check it in your tendering software before you submit it.
What changes
What goes into the X84
As GAEB DA XML 3.3 requires: item numbers, unit prices, item totals, section totals and the net total, plus the bidder. An X84 repeats no texts; they stay in the client's X83. Totals are rounded per item as GAEB rules: total = quantity × unit price, rounded to cents. Alternative items and contingency items without total get a unit price only. Bidder text supplements (such as the product offered) and markups are not filled in yet; the report lists the items concerned.
FAQ
Questions about converting GAEB files.
Open the X83 in the converter, enter a unit price for every item and your company address, then download the X84. The converter computes the totals.
Yes. Export the price sheet, enter the unit prices in the yellow column and load the file back. A key column links every row to its item, so the rows must not be moved.
The converter does not write the X84 and lists the items without a price. Alternative items and contingency items without total need a unit price too.
Because GAEB defines the X84 that way: the bid carries item numbers and prices, and the client's software takes the texts from the X83 it sent.
Check it in your own tendering software first. The converter is new and not certified by GAEB or BVBS, and a faulty bid file can cost you the tender.
