If you need an RFC4180 compliant CSV format, use TCSVDataSet instead. Depending on the flavour of CSV, this format may be close enough to what a reading application expects to function. Note: FPC 2.6.x and earlier store sdfdataset data in a format that is not completely CSV or completely SDF compatible.Īs indicated, SDF differs from CSV. tab characters are removed when writing out data using StrictDelimiter:=false SDF formatįree Pascal offers the TSdfDataSet, which stores data in SDF format. When writing out CSV data, set StrictDelimiter to false and output the DelimitedText property. Tips: when reading CSV data, set the StrictDelimiter property to true. Note, however, that DelimitedText is supposed to be in SDF, a Delphi-specific format that is very much like CSV, but does not conform with RFC4180 completely. This parses a line of text out into separate fields. TStringList offers the DelimitedText property. It offers both line-based and document-based access. See SDF for more details.ĬsvDocument is a robust implementation of both the RFC 4180 CSV format and the alternative Creativyst/Excel CSV format.

using the FPSpreadsheet code).ĭelphi (and Free Pascal) have a very similar (but not identical) format, SDF. However, as Microsoft Excel may interpret some fields such as date fields differently depending on a user's OS locale, it may pay to find alternative ways of transferring data (e.g. Spreadsheet packages such as Microsoft Excel and OpenOffice/LibreOffice Calc are able to export to and import from this format. Jim,Weston,19560818,"Also known as ""The Butcher"""Īpparently a header line is used here, as is quoting using double quotes. RFC4180 tries to codify and standardize existing practice it makes sense to conform to this standard when writing CSV data (and accept all RFC4180 data when reading).Ī different, Creativyst/Excel, CSV pseudo-format specification can be found here.

line endings (#13 and/or #10) may or may not be allowed in field data.

field data containing delimiters may be prohibited or enclosed by quotes (most commonly the double quote character).there may or not be a header line that lists the field names.data fields separated by commas (or, in variants, other characters like tabs and semicolons).3.3.1 TSdfDataset and TFixedDataset sample filesĬSV means Comma-Separated Values, and is a popular file format that is unfortunately not completely standardized.

Pressing and releasing keys by software.

To include quotes in strings, put them in twice like this "1",""2" which produces items 1 and "2 It will take both 1,2,3,4 and "1","2","3","4"Īlthough "1","2,3","4" would give only three items as commas inside double quotes are ignored. You can do this in reverse as well, take a stringlist and create a single line of items all comma separated.Ĭommatext also handles strings and commas by accepting double quotes around items.

This example shows how to read in a CSV file and when you come to process the line of text, it has been separated in ts.count strings thus making it easy to process.

The Tstrings/TStringlist classes have the commatext property which allows you to assign a string full of comma separated items and have them automatically separated. The Tstrings/Tstringlist classes have a property that will do this for you. Question: Sometimes you dont need fancy parsing classes- reading a CSV file line by line is one such case.
