The title line. Spec Register Builder starts a section where a line such as SECTION 03 30 00 - CAST-IN-PLACE CONCRETE appears at the top of a page. The separator can be a hyphen, an en dash, an em dash, a colon, or nothing, and a title printed on the line below the number is picked up too. Section 01 33 00 - Submittal Procedures and SECTION 09 91 23 PAINTING read the same way.
Number formats. Current MasterFormat numbers are six digits in three pairs, such as 03 30 00, with an optional fourth pair for level-four sections, such as 31 62 13.13. Some books run the six digits together as 033000, and older master specifications use five digits, such as 03300. All of these are read. When a book prints both, as in 03 30 00 (03300), the six-digit number is kept.
Titles as printed. The title in the Section Title column is the one printed in your book, not a title from a reference list. Spec Register Builder carries no table of section numbers or titles of its own, so a project that renumbers or retitles a section keeps its own numbering in the register.
Where a section ends. A section runs until END OF SECTION or the next title line. A table of contents page does not start a section, a section title repeated in the running header does not split one, and a cross-reference to another section in the body text is read as text.
Printed pages. The printed page on each row comes from the section footer: 03 30 00 - 3 and 01 33 00-1 in CSI style, Page 2 of 12, Page 03-1 numbered by division, or SECTION 01 33 00 Page 2 in UFGS style. The PDF page is recorded as well, so the row works for both the paper set and the file.
Division order. Choose the Section header to sort the table by section number, which puts the rows in MasterFormat order, Division 01 first; choose it again to reverse the order. The export holds every row in book order, section by section, and the Spec Section column filters cleanly in Excel by division or by section.
From list to log. Export XLSX or Export CSV writes the list with fourteen columns, from Spec Section to Notes, plus a Manifest sheet in the workbook with the source file’s SHA-256.
