CSV Bridge 0.1.1 — Free Windows x64 Evaluation
PMC Labs Studio | https://pmclabs.studio

Inspect a CSV locally and export a new XLSX with every cell stored as text.
This helps preserve leading zeros and long identifiers that are still present
in the source CSV. It cannot recover values that were already lost.

GET STARTED
1. Extract the entire CSV-Bridge folder. Keep _internal beside CSV-Bridge.exe.
2. Open CSV-Bridge.exe. No Python installation is required.
3. Choose samples/catalogo-pt.csv. Choose UTF-8 and semicolon, then Analyse.
4. Optionally select only Preço in the decimal-column list.
5. Export text XLSX to a NEW filename. All cells, including prices, remain text.
   Use your spreadsheet application to convert selected values for calculations
   only after checking the result. Existing destination files are refused.

SUPPORTED INPUT
CSV/TSV with a header; UTF-8, Windows-1252 or UTF-16. Auto-detection or explicit
comma, semicolon, tab or pipe separator. Limits: 10 MiB, 100,000 data records,
256 columns. Preview: first 100 records; scroll horizontally for more columns.
The preview uses arrows for line breaks; exports retain the original content.

OPTIONAL PORTUGUESE DECIMAL CONVERSION
Select only columns whose values use Portuguese notation. For example,
1.234,50 becomes 1234.50. Invalid/ambiguous formats are refused. Unselected
columns remain unchanged. Selecting an identifier column may change its values.

OUTPUT AND DIAGNOSTICS
Text XLSX has no formulas. UTF-8 CSV includes a BOM; opening CSV directly in
Excel can still trigger automatic type conversion. Formula-like CSV values are
refused unless you explicitly enable apostrophe prefixes, which change values.
Diagnostic JSON contains issue coordinates and a checksum, without cell values.
Source files are not overwritten. No accounts, uploads or telemetry.

EVALUATION STATUS
Unsigned executable. Native GUI and Excel tests were performed on the
development Windows PC. A separate clean Windows machine and an external
customer workflow have not yet been tested. No claim of universal compatibility
or measured time savings is made. Read TESTING-STATUS.txt for coverage limits.
This is a free evaluation, not a Microsoft Store release. Do not disable
Windows protections to run it. If your device blocks it, keep it blocked and
contact us; Python users can inspect and run the included source separately.

FEEDBACK
pmclabs.studio@gmail.com — subject: CSV Bridge feedback
Tell us your Windows version, chosen encoding/separator, the error message and
whether text XLSX solved your task. Do not email confidential CSV files; use a
small fictitious example if needed. We do not promise a support response time.
