Convert FP3 to XLS

What the FP3 format is

.fp3 most commonly identifies a FileMaker Pro 3 database. It can contain records, tables, fields, layouts, calculations, scripts, value lists, relationships, and container data. Older FileMaker installations and archives are the main sources of these files.

.fp3 is also used by FastReport for prepared, rendered reports. A FastReport FP3 contains report output rather than an editable database structure, so identify the file’s source and the application associated with it before selecting a conversion method.

What the XLS format is

.xls is Microsoft Excel’s binary workbook format used by Excel 97–2003 and many older business applications. It supports worksheets, formulas, formatting, and basic charts, but each worksheet is limited to 65,536 rows and 256 columns and cannot represent many newer Excel features.

Use XLS only when the receiving application requires Excel 97–2003 format. For newer systems, .xlsx is generally the better export target because it supports larger worksheets and newer workbook features.

Convert a FileMaker FP3 file

1. Make a backup and work on a copy. Do not attempt conversion on the only copy of an old database.
2. Open the copy with a FileMaker Pro release that can convert legacy FileMaker files. FileMaker Pro 7 is a commonly used conversion point for FileMaker Pro 3–6 files, but it may require an older operating system or virtual machine. Use a licensed installer and confirm the release’s supported source versions.
3. Allow FileMaker Pro to create a converted copy, then open that copy. Check tables, fields, relationships, dates, calculations, scripts, container fields, and record counts before exporting.
4. Display or find the records to export and choose File → Export Records.
5. Choose an Excel export option. If the release offers Excel 5.0/95 or another .xls format, select it, choose the fields, and save the result as records.xls.
6. If the FileMaker version exports only .xlsx, create records.xlsx, open it in Microsoft Excel or LibreOffice Calc, and choose File → Save As followed by Excel 97–2003 Workbook (*.xls). Review the compatibility warning before saving.

FileMaker’s export is a records-and-fields export, not a conversion of the complete database. Layouts, scripts, relationships, privileges, value lists, and most database behavior do not become XLS features. Container fields may export as references or separate files instead of embedded worksheet content.

Convert a FastReport FP3 file

1. Open the file in the FastReport designer, viewer, or reporting application that generated it. FileMaker Pro and generic spreadsheet converters cannot interpret a FastReport prepared report correctly.
2. Choose File → Export and select Excel 97–2003, Excel 5.0/95, or the equivalent XLS filter provided by that FastReport product.
3. Configure available options such as one worksheet per page, page breaks, report-object export, and formatting preservation, then save the output as .xls.
4. If only Excel XML or .xlsx export is available, save that format first and convert it in Excel or LibreOffice Calc using File → Save As.

A FastReport FP3 represents rendered report output. Merged cells, positioned text, images, page headers, repeated labels, grouping, and subtotals may produce a worksheet that looks correct but is difficult to edit. Calculated or grouped report values may not include the underlying source records.

Online conversion options

Do not expect a general online converter to extract a FileMaker FP3 database reliably. Services such as Zamzar or CloudConvert may support XLS conversion from common intermediary formats, but their current format lists should be checked; support for proprietary FileMaker or FastReport FP3 files is not equivalent to support for XLS. For sensitive records, avoid uploading the file and use FileMaker Pro, FastReport, Excel, or LibreOffice locally.

An online service is reasonable only for non-confidential data after the source application has exported the content to a supported format such as CSV or XLSX. Verify that the service explicitly accepts that input and produces XLS, then inspect the downloaded workbook.

Quality and compatibility checks

Compare source and output record counts, inspect dates and decimal separators, verify non-ASCII characters, and check multiline fields. Treat identifiers such as 00127, telephone numbers, and long numeric strings as text so spreadsheet software does not remove leading zeroes or convert them to scientific notation.

Check formulas, totals, column widths, worksheet count, images, and records near the XLS row limit. XLS may truncate or alter data when the source exceeds its row, column, cell, or formatting limits. Preserve the original FP3 and the intermediate converted database for archival use; the XLS file is an extracted spreadsheet, not a reversible replacement for the source database.
